CVT Issues, it feels like it starts on 4th Gear

Hi,

I took apart this old CH80, 1987, replaced the tranny bearings and cleaned the carb. After I finished I noticed the rear wheel makes a grinding noise, it is not smooth and loose, but it rotates freely, so I don't care too much about that noise.

Anyway, it starts with one touch but it has no power. The carb seems fine and the idle appears good. But the start has a very sloooooooooow acceleration. Actually, I can stop the scooter with my feet.

This should be the Pulleys CVT or the belt. I bought a new belt online and I am waiting until it gets here, but I am wondering if there is anything I should check on the CVT shoe pads. The scooter took some water and it generated rust on the CVT.

I used pb blaster and loosen up the pads, then I used electric engine degreaser, carb cleaner and brake pad cleaner to get rid off all the oil.

The thing has a little better acceleration, but still no prize.

Any help is greatly appreciated it,

F

the roller weights in the variator may have flat spots worn on them, take the driven face off and check, might as well leave teh plate off of the back of the variator when you put it back together, it only restricts the movement :D

If it's not one thing, it's the other.
I'll check the roller weights, I just want to ride this thing!

The speed you have is how fast you run your mouth and lie. You sure your name isn't obozo and you live in DC?
