A friend gave me his Goped to repair. I have had good luck with 4stroke motorcycle engines. This has a RC230 engine Wellbro carb. It was very hard to start. Only would run about 20 sec. at high RPM. So far I rebuilt the carb, All new bearings, seals, gaskets, Piston ring, Head gasket, Lots of nice blue spark at the plug. But will not fire at all. New gas lines and filter. Tried spraying carb cleaner in the carb, No fire. I'm out of ideas. Can anyone help Thanks Mike

We use that same engine in our 1/4 radio control cars.

this thing must be small.

the carb can be rebuilt BUT almost NEVER will work, correctly.

a new carb is $40.00.

coil air gap is very easy to miss adjust.

any air leak, crank seal, cylinder base gasket, carb gasket, will cause it NOT to start.
