Scoot is Acting very Funky By luvmyscoot (Read 1,324 times)

GOOD ONE LUV(HAHA), I take digs very well and give them out once in awhile to. Gots to have some joking around and not take this stuff to seriously.

But let me ask this can you put up a picture of your carb and measure the inside of the front by the edge and that will tell us what size it is A 30mm or 32mm etc..

What was different in the parts that came from what is in your carb? DID you match them up what was different ??

Sorry about the little delay in responding, my job shift was changed yesterday (I'm trying to get acclimated.

Tomorrow (Saturday after I get off work, I'll snap a few photos).

everything in the kit looks fairly similar ( I did not open up the carb all the way). Guy on the phone from the shop said that the jets probably will not work. Needle looked close. It is adjustable with the clip.

diaphragm looks about the same except for the lower hard plastic end. the one in the kit is basically a circle. The one on my scoot has a half semi circle on one side and a flat squarish section. Ill photograph it to show what I mean.
thanks again for the help.

do you think there is a way to remove the soft diaphragm plastic and install it on the hard plastic section of my old one?

[Alleyoop]

They are supposed to come apart I have never tried it but I have a few laying around I will try and see if I can separate the Plastic Circles that hold the rubber Diaphragm.

I had a little time to work on the scoot today.

No camera this weekend (daughter took it).

I was able to find the plastic v-slides (online) that run up and down in the variator. The thing does not bind now (I cleaned and re greased it all with white grease and installed new ones). Now it is much more quiet and seems to move between gears better.

Raised the idle a little to 2K (back wheel spins but it is ok). Messed around a little with the A/F screw. Did not make much of a difference.

Tach will not get above 5K still. (but at least bike is running again).

going to try to take soft plastic diaphragm from new (and wrong) kit and put it on old hard plastic portion of diaphragm.

Alleyoop, did you by any chance try to take apart an old one and see how to do it?

thanks again

Yes I did try it, I got the rubber out but I could not get the bottom plastic off. It appears to lock onto the top plastic the rubber has the same diameter circle as the cylinder but to get the rubber part back on you have to get that bottom plastic off so you can then slide the rubber diaphragm and then the bottom plastic to lock it in nice and tight so it does not leak air.

OK I just broke the bottom plastic and found out how it is put together(HAHA).

The top of the cylinder where the plastic pieces fit is SMALLER in diameter than the rest of the cylinder. So how they are but together is either of one of two ways.
1. The plastics are hot and soft when put on so they will slip from the bottom of the cylinder up to the smaller diameter on top and then as they cool they contract around the smaller diameter of the cylinder.
2. Or if you notice the top of the cylinder is spread out, so in this case the the bottom plastic gets put on then the rubber diaphragm and then the top plastic and then they spread out the top end of the cylinder over the top plastic.

So I would say NO WAY you can change the rubber Diaphragm.
But it is interesting that they do SELL just the rubber Diaphragm

Thank you alleyoop. I guess it's back to the drawing board again

I got to go away for training for work this week to the Bay. I'll write this weekend when I get back.

Thanks for trying to take one apart for me. If I did it It would either cost me the 30 bux for the kit I have or the 200 for the new carb!!!!

Sorry you broke one of yours on my account.

No problem they were spares when they had a deal 3 carbs for the price of two they threw in 3 diaphragm and fuel filter for each of the three carbs. So they where just sitting there so it was a good science project really, now I know how they are put together.

Well, I returned the kit that I bought that was wrong today. I also broke down and bought the full new Japan made carb (after speaking to the mechanic or owner or whoever he was "Joe"). To be sure that it is absolutely the model I need. It is on it's way now.

Shameless plug:

Big and Little Scooter Parts on Ebay and physically out of the California Bay Area. Seem to be very nice people. They gave me no problems with the return and helped me with the price of the new carb because of the trouble we have had.

Wahoo I should be riding fast again in a few days!!!!!!!! ;D ;D ;D ;D

Hi Richard,
Thanks for the link and the help.
Unfortunately that is the one in my kit that I returned. if you look at the photo in the top right portion (the hard plastic portions shape is completely round.) On mine the rear (lower towards the needle) portion is round and the front is a cut out square shape. This one (photo) goes to the vertical engine. I have the horizontal version.

Thank you again for your help
Dave

Sorry, you have the same as mine, I'll keep looking.

Hi Guys,

Just a quick Note. She screeeeeeeeeeeams now!

All it took was a new kei-hin (probably spelled wrong) Japanese carb.

I had her up to 90 on the china-o-meter (probably about 80mph in real life) That is plenty fast on
a little scooter.
Thank you all again for your help and advice.
Dave

Wahooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo!!!!!!
