Got a petcock yesterday for my 77 motobecane 50v, and after some minor carb work got it to fire off. Now, mind you, it doesn't run all that well, it's missing the air cleaner assembly (still not sure exactly what I'm going to do about this) and will idle decently if I restrict the air flow with a piece of cardboard.
Once i got it to run without stalling out I took it out into the alley to see if it would go. And it will. Slightly slower than I can pedal. Giving it gas seems to have no effect whatsoever, it just bogs down more. I can get it to rev up on the center stand, but with rider weight it doesn't seem to want to do anything. The belt is aligned properly and does not appear to be slipping. The engine pulls back as it should and the variator appears to function properly.
Where should I start? I have a decent idea of where to go, but I want to know of any specifics I should look for so I'm not taking shots in the dark. Thanks!
