New Puch carb High idle

Kevin Carey /

Well...not really idling...Just put on a new 15mm bing and 15 mm intake. I'm using a red foam filter(not oiled yet) and when I start the engine it just wants to over rev . I have to turn it off for fear of a seize. Throttle cable is not over tight. Any ideas?? I'm going to check for air leaks first.......

Is your idle screw all the way in?

Re: New Puch carb High idle

you say "Throttle cable is not over tight"

but, make sure the throttle slide is going all the way to the bottom

Idle screw adjusted in and out...not much change. I will check the slide to see if its dropping all the way.

Piston port and really most mopeds idle high when cold then calm down when warmed up

But ya your prolly not jetted/tuned correctly yet
