SOURCE: I have a Kymco People

have you checked the spark plug? take it out and lay it on the engine touching a metal part and kick the bike you should see it sparking if not then replace the spark plug
if thats not the problem then give the carb a clean and check the air filter that its not blocked

2 stroke bikes need three things to work air spark and fuel as long as you have these it will work

hope this helps

John

I have an '87 Olds Calais 3 liter engine that idles rough, hesitates on acceleration, and just recently stalls and won't start.

Karl, have you confirmed good fuel pressure? It sounds like a weak fuel pump to me. Is your Check Engine light on? If so what are the codes in the computer?

Just purchased a 1994 Firebird, took it in for a smog test, and it failed at 15MPH, measuring 522 while the max allowed is 483. Car had been in storage for two years with the battery disconnected. Also low...

522 what? Get it registered. Yes it needs to be driven, Yes do an oil change. Add some injector cleaner, I recommend Chevron TECHRON fuel system cleaner. The shop that is checking it most likely knows what it needs to be repaired. If you dont trust them to properly repair it, find a different shop.
