Hi,I recently purchased a 2000 Whizzer (eBAY)I was told it ran great.Come to find it did not run at all.The carb was dumping gas out the air horn, found the flywheel bolt was broken off. I took off the flywheel cleand the magents,and the mag. Exstacted the broken bolt,replaced it, and put a new 22 mm carb.on it.I also flushed the gas tank and replaced the spark plug. It ran very well at first, but now it's running very speratic. At times it runs well, and then it goes to being hard to just keep running. If i leave the throtle in just the right spot it will stay running, but if I move it at all it stalls.then for no apparent reason somthing changes and it runs great again.I've ordered a coil for it and should be receiving it soon, But I don't think that's the problem.Any thoughts what I shold be looking at?
