I recently bought a used motorized bike.
The previous owner said it was a 49cc, although I don't see the displacement stamped on the cylinder anywhere.
It has a CNS Performance Carb like this one:
I have a few problems.
1.) The carb doesn't fit tight on the intake manifold
2.) It seems to be running RIDICULOUSLY rich.
I moved the clip on the throttle slide needle to the top groove and the mix screw is all the way in. When it runs, any throttle immediately kills it, and is accompanied by gobs of smoke out of the muffler and even fuel dripping from the muffler. Even left to idle it eventually gets very smoky and dies. When this happens and I take the plug out, it's wet.
Any ideas on how to fix the carb fit and the mixture problem?
Anyone have a stock carb they want to trade for a CNS?
(One more thing) The bike originally had an AutoBike 5 speed automatic shift system, but the derailleur is pretty much trashed (bent beyond repiar). I was just going to shorten the chain and add a masterlink and make it a 1-speed. Does that sound like a resonable (cheap) solution.
