Well, the new cdi came in today.  No clue who made it... but it looks like it was produced at a different time... maybe on a different factory line.... has FS300 ink stamped on it and I forget the name of the company.



I put in fresh pure gas... non-ethanol after I put in some Pri-G.  Scooter started right up...I could turn the throttle (at the carb because cables are only partially installed, and not hooked to carb, yet.  When I turned the throttle, I could do it slowly up- only to a certain extent before the engine would seem to be bogging, or not getting any more benefit from me attempting to go higher.

So, I idled for awhile and ran it up slightly off and on for about a half hour until the gas coming through the filter began to look alot more clearer like 'pure gas' vs the ethanol gas (probably water-logged) that was in the lines for 2+yrs.  I should say that also during that time I tried adjusting the Air/Fuel Mixture screw on the side of the carb... and I couldn't find a sweet spot..  The scooter HAD already warmed up and I believe the enricher cut out as it should... but turning the screw was not really giving me a definitive good spot...I could pretty much kill the engine by turning the screw all the way in.... and then coming out to 2 turns, 2.5 turns... well into 3 turns had not much effect.

So, once I reached the point where I believe the Pri-G (which is more than a Sta-bil type product, it renews old gas (as there was certainly still 'some' left in there even after I siphoned it off a few days ago)....that and the new gas must have been getting into the carb because it reached a point where it seemed anyway that I ended up at about 2-1/2 turns out....and I was able to "rev" the throttle to probably 90% (that's all I went, it is a little painful on the hand doing it right at the carb) and it responded quickly and did not seem to bog down at all...

After testing this up and down on the throttle for awhile....I was as satisfied as I could get at this point...feeling that I was pretty close on the A/F mixture.  Mind you this is with the OEM airbox, and a  massive air leak where the sealant was separated for most of the time prior to my move out here to albuquerque... So, for most of the 2yrs I rode it before I parked it. I did not know of the leak until well into my 2yrs of riding it. I need to seal up that leak where the rubber hose that is attached to the back of the carb, meets up with the airbox itself.  That might change the air mixture and so I understand I'll need to probably do the sequence I mentioned above, again.  I am at about 5200' or slightly higher, and above 4000' once I get it to the point of riding it regularly here in ABQ.  Not at the point of riding it at all, yet.

I'd like to go to a uni filter or something similar and I do have plenty of bookmarks in my bookmarks file for those.  I can take my harbor freight caliper and verify the size in mm where it would hook to the intake somewhere.


I think I am 'not' going to worry about the gas gauge (float has a slight stick since I got it originally, however when I filled up in the past, it goes end up at the correct level within a short time of riding, and today wen I put in 2 gal the gauge didn't move- until I realized I had its connector previously disconnected in anticipation of removing the gas tank to get at the sensor.  Hooked that up and read below half, but over 1/4...  I'm sure when I put another 1.2 gal in plus what little I burned off today, it will come up without much problem, even if I have to shake it on the center stand.

So, I think my next steps are see if it runs this good again tomorrow... then Monday (got stuff I have to do on the weekend) Work on my right rear turn signal, as the bulb is out (fast beep/blink when I turn on right signals.. and front right works... so, order bulbs/ or go to store...superglue the socket on the outside one I verify with a meter it does get 12 blinking... socket is not broken all the way through...order the filter because if I eliminate the OEM airbox (it's already leaking past it anyway...so it's ineffective...I'm thinking a uni filter won't be much different if it requires any mixture adjustment at all... (in my case since air is going 'around' the filter).

Then, I can start looking at putting the plastic parts going from the foot rest (whatever you call it, to the parts that go on before the seat... then put the battery in it's rightful place, and the start relay... then look at all the fasteners because many of them were 'in' the trunk part, which was outside for a long time and did get water back in Texas, so some fasteners while still good, will need derusted... anyway... on and one... but very encouraging that it ran decently today and I 'think' I was able to get the mixture adjusted reasonably well...   Yay me! LOL....

Great news, on the CDI !
I wouldn't draw any conclusions about how it's running until you have the air intake sealed up though. If you're not getting the correct air/vacuum, your carb will not give you a true reading. Make sure your hose connections are not leaking and that the manifold seal at the front is good. Once you have all the air in check, you may find that sweet spot.
It's time for a scoot for me, today!

Oka, gotcha cloudsifter .

I'd consider some silicone RTV rather than an epoxy or glue. One can even find it at the dollar stores nowadays. In case you're not aware (Its not immediateely visible) that air tube has a tongue and groove fit going onto the port, to sit correctly too. Yes, a length of open ended fuel hose to route any overflow away should do, I would say.
Rotso ruck!

Had some time this afternoon, so took off the airbox and scraped out the old rtv they had used in that tongue and groove area. Going to see if I have some RTV around, or a trip to the store will happen tonight or tomorrow.

So I am to gather that ultimately the CDI was the main culprit ? Of coarse beside the small little maint. and nip and tuck problems ? If so Good show in trouble shooting your problem , help or no help. When you have compounded problems plagued by an electrical problem also, Can't get much harder to diagnose my friend.

At this point it does appear that the original CDI was the culprit. It took two years back in Texas to go bad... I ordered another and some throttle cables (one of the OEM ones was frayed) and then had other things on my plate. The CDI I ordered 'could have' been exposed to the weather (rain included) in it's little cardboard box... and the bag it was in wasn't sealed. But being dried out here when I pulled it out of the bag- no way to know what condition internally it was in.

But, for the past few days, using the CDI I ordered earlier in the thread, recently- I have has started the scooter up and it has remained running for several minutes, and warmed up...and I turned it off. So, it does appear that a known brand new CDI has fixed the problem... I've yet to put it all back together and ride the scooter for the true test, as I am juggling my time.

I sealed up the air leak on the airbox with some black RTV, inside and out and it looks decent. Hopefully it will hold.

I'll add pics in this thread/post when I take a picture of that in a few min. The RTV was dry yesterday.

One of the mounting spots on the lower forward of the airbox broke before I moved so, now that the RTV is dry, I will use some epoxy to try and affix that piece back to the bottom of the airbox and see how that goes.



Lastly, a spot where my tire had worn through the airbox when one of the mounts failed. I rtv'd that too.

So far things are turning out pretty good. I have no worries.

Man ! That air box was taking a beating. I know why your scooter got all screwed up Dude. You were trying to compete in Moto Cross racing with it it looks like ! "Scooters aren't for that"

  4950cycle Ha ha, you would think, huh?  Nah... the airbox really was 'not' airtight from the factory.  I didn't know it because I didn't have a reason to look at it during the 2yrs (2012-2014) I was riding it..   I saw it, but thought it was normal for awhile... and my scooter ran ok. I did a valve adjustment on it, as it was time according to what I was reading, and boy did it improve things back then from good, to great. 

At some point the lower forward mount for the airbox just literally went to pieces, like 'crumbled'. I never crashed or anything... it literally just fell to pieces.  Since it still stayed in place, and was not dragging on anything. I didn't worry... but eventually it dragged, but I realized it and repositioned it slightly and it didn't drag. Now, in 2016 that I am in Albuquerque and want to get this thing back on the road (Pure, non-ethanol gas out here in a couple of places, too!) I am trying to do some things while I have most of the plastic off... Maybe actually use the wire I ran from the battery t the front, to put on this for example....Triple Function Dual USB Charger + Voltmeter + 12V Outlet Socket Panel Jack
or maybe this Atach Digital GPS Speedometer Gauge 3-3/8'' (85mm)  but it's pricey, so maybe not right away.

Right now I'm jugging things, and need to drive a family member to an appointment today...but so far with starting scooter for a few min daily- things are continuing to run GOOD (maybe 'GREAT' but not back together to ride it yet.


I MIGHT go purchase some 3/16" fuel line to replace the 1/4" inch that I replaced the OEM lines from China with.  I've found that with everything off so i can see thing- that the 1/4" even with the hose clamp cinched down really good, almost wants to come off, and actually did come off the outlet side of my mikuni fuel pump... so I'm thinking I'll go back down to 3/16" but the good stuff.

[4950cycle]

Got my fuel pump today. pretty sure that's what is wrong. But I hope I don't have CDI trouble too. Now ya got me skeared ! The trouble my scooter is having can act similar in some ways. Just started a week ago when it stranded me. PS I will have to do the same with my fuel lines also

Well, hopefully that fixes your problem.  If it doesn't, and you have the 8pin cdi... this is where I got mine from a few weeks ago. You can find them all over ebay and the net for various prices, some VERY high for the same thing... and some reasonably priced in the $20's.. plush shipping.


Ebay CDI
if that doesn't work, the ebay username for them is partsfox2009  . There are a bunch of places you an get the cdi...even direct from china (on a slow boat) on aliexpress... but, I figured I'd have the most recourse if something didn't work- with Ebay.

So, far for several days it has started up without failing.  Knock on wood.

I've been reading the forums since there was scootdawg, then Itstheride, and I'm here now... and I remember back when I got my 2008 Linhai Aeolus 300 it was in 2012...(brand new, in crate) and by then, there was 4 years of history and I remember the two issues where there 'might' be failures sooner or later was the fuel pump. Some stayed with a vacuum pump like Mikuni DF44, and there are rebuild kits available for it as well pretty easy. Some decided to go with an electric fuel pump and you can find their posts in the forums. Some also got regulators so they could dial down the pressure so as not to overflow the bowl. Others got whatever they got and didn't get regulators.

The other issue I remember was CDI's going bad... Some call them TCI's.... but whatever they are- the common name that has stuck is CDI and you can find them searching that term... Be sure you are getting one for any of the various names for the Aeolus or linhai 260 or 300 and other names you can see when you search on ebay....

So far it looks like it fixed the problem (Fuel pump). Then put my scooter up on the center stand and took it up to the rev limiter a couple times to find out where it topped out. The RPM went up to about 8400 without breaking up at all. Any higher and the RPM was unstable. But it would go up to about 8700 as indicated on the not so precise scooter tach. What that means is I might get my 5 mph on top if my variator isn't maxing out already. And 16.7 HP will haul my 260 lbs any faster than it already will go. While I've got the belly and side exposed I am gonna do a much needed valve adjustment. " Again " About the 4 th one I've done. Sorry, no thread high jacking intended. Glad your getting some place on your scooter project. Looks like you'll be riding sooner or later Cloudsifter.

4950cycle No biggie... I didn't take anything as thread hijacking.

Show me a pic of your scooter front end and I might be able to tell you which windshield. I at least know exactly just by looking at it which windshield fits the Honda Reflex looking Chinese 250 scoots.

Those are pictures from back when it was new. No trunk now, I added that, but it broke off.

From my bookmarks, these might be some possibilities if I ever do decide to go for a bigger windscreen/ windshield.
