Re: New Member *Round Rock, Texas*
Kingkay, welcome to the forum. We're glad you've come to us for help. Let's see if we can't get you going.
My first question will be, did the engine ever run correctly? Are the problems you're having new or have you always had them?
A fast, high idle speed is a classic symptom of an air (vaccum) leak somewhere in the intake circuit. The most common places are the carburetor where it attaches to the intake manifold and the intake manifold gasket at the cylinder. There are other areas but let's start at the most obvious places first.
You also said the kill switch doesn't work. How is it wired? It should jump between the blue and black wire from the CDI to the magneto. Cap and isolate the white wire if you're using it.
What "upgrade parts" did you install? You said "throttle and CDI". Are you using one of the aftermarket CDIs? If so, try the one that came with the engine. As for a throttle, what do you mean? The twist grip? If so, it is possible the throttle isn't returning to the idle position and the cable needs to be adjusted. Why did you replace the throttle?
