There are a few things you need to check. From the kill switch there are a couple of wires. Disconnect one of them just to prove the kill switch isn't the spark problem. Then like F_R says. Pull the flywheel and look at your points and coils. If coils are cracked, replace them. Points should be very clean and gaped to .020. Take your time and get them right on the money. Once your done make sure you torque the flywheel to 45 ft. lbs. You have more to do but that is a start towards getting your spark back. Best of luck. Rick.
