Yeah, it's just too bad scrappydog doesn't carry manual choke conversion kits/parts.


I toyed around with the auto-enricher. It works fine - extends and contracts just like it's supposed to. With it removed completely, the scoot is still hard to start - does the exact same things listed in my previous post. Anyone have any ideas? I've been unable to ride the thing for weeks now.

Ok, did a lot more tweaking last night.

High idle was caused by a mis-adjusted throttle cable. My own dumb fault. That's what i get for working on the scooter while not drinking.

Took it out for a spin after getting the cable sorted and it ran pretty well, up until it died at a stop sign. Wouldn't start back up. Poke around and find that the A/F screw fell out. I guess 8 turns is too much. Fortunately, it landed on the CVT case. Put it back in, adjusted it out to 3 turns out and the scoot just ran like crap. It's way too lean with the 75 main and the UNI filter. Swapped in the 90 main, set the needle shim to the middle position, set the A/F screw to 2.5 turns.

Scoot ran pretty well. About where it was before when i was hitting 45mph on it. Idle at 2k rpm. Didn't speed test it to confirm top speed, and it would still run up to about 5500rpm, then back down to 3500 before slowly working it's way back up and to 8k.

Installed the new performance variator, 5g rollers, and a new belt. On a full throttle launch, the scoot bogs hard for a second, then spins up to 6500 rpm, and stays there. it was getting late, and i had some errands i had to take care of, so i didn't take it outside of my neighborhood - don't know how it'll run above 30mph.

So I figure the bog is probably a combination of roller weight and tuning. I haven't checked the plug since the 90 main went in. Any advice here would be great.

New problem... this morning, it was really hard to start. It would start to catch and then die. Had to give it throttle to get it to finally catch and run, and then it idled at 600rpm. At this point, if i gave it any gas, it would die again. Let it run at idle for a bit, and the rpm slowly came up to 1200. Then I could give it a little gas, and get it going okay. When I hit the stop sign at the end of the street - it died, and i gave up.

So, it started and ran great last night when it was fully warmed up. this morning, cold, it was a PITA. The fuel enricher worked fine when i tested it last week. Is this a choke or tuning problem? I'm seriously considering ordering the parts to convert this to a manual choke.

I tested the enricher before i pulled the carb - it works - but i'm going to end up replacing it with a manual choke and handlebar mount lever.
It's possible all manner of things were clogged in the carb. When i pulled it apart, everything was coated in a yellow gummy film. If you're from the south - imagine a car parked outside for several days with no rain in the spring - a nice thick pollen coat. now, pollen shouldn't have been in the gas, and the scooter has never sat more than a couple of days since i bought it, but... i think i'm going to blame the ethanol in the gas combined with the sealant coating in the tank plus the fact that i only just now swapped out the stock fuel line.

I'm going to see if i can find a local source for the pilot jet. I''d already ordered a new 90 main from monstergy6, along with a new manifold and variator setup. i guess i'll try a true 35 pilot, and go from there.

Yeah - it's baffling me, too. The scooter was purchased new - no one has been into it but me, and this is the first time I've cracked open the carb.

My camera battery is dead at home, and i didn't bring the parts in to work - which i may end up having to do to measure them with real calibrated equipment.

Eyeballing it - the hole in the pilot jet is noticably larger than the hole in the main. The pilot looks to be almost 1mm in diameter, and the main is closer to half that. But those are eyeball guesses.

The carb I have is almost identical to the one in the big guy carb cleaning video - the fuel enricher mount is cast into the carb (not removable and able to be blocked off with a plate), the jets, float assembly all look the same. The only difference I see is that my cap for the diaphragm and slide is brass instead of black plastic.

I know I'm going to have to fix the manifold issue first - I'm hoping someone can identify and/or explain the jetting to me so i can order all the parts i need at once (the scoot needs a new belt, and i want to upgrade the variator and rollers/sliders as well).
