Mine won't Idle

Ok.. Since I bought this one pre-built, and did not do it myself, I got no directions and I am just learning it.

The engine will not idle.. It runs fine when I work the throttle, even after warming up.

How do we adjust the idle speed on these little chinese engines.

Also, can we shorten the throttle cable at the carb any? I have both adjusters spun all the way out, and there is still a little play in the cable and I could get it tighter, maybe a little more throttle.

THANKS.. I am working on motoring my other OCC chopper in Feb. I am going to start ordering parts soon!

Sorry, It is a 2-stroke.. so oil/gas mixture.

It is kinda a crappy install, but does work, nonetheless.

Maybe after I shorten the cable, I can pull it just right to keep it idleing. It kinda runs out a little too, then goes down, then promptly dies, if I don't flutter the gas.

on adjusting the little screw on the side, somebody clue me in as to what this screw is.. Is it the mixture screw, to lean it out, air/fuel, etc? I have seen about adjusting some kinda clips too.. what is that? I don't want to mess with jets. I got my wireless bike computer on it, set it for the front wheel (OCC chopper, 24inch), and it goes 25-26 max speed with my big butt on it and the engine not workin to hard so I will leave that alone.

My next build, I am considering a jackshaft, gear cluster, tuned pipe, etc. That build will take a little bit of money. I got a perfect condition OCC to put that on.

Thanks for the input.
