When it idles, it keeps on missing every few seconds. I'm gonna replace the plug and check to make sure no vent lines are plugged or anything, but if that doesn't work what then? When I rev it the throttle sticks some and there is a slight hesitation and then it either settles down to the proper rpm for idle and starts the missing or stays at a higher rev than it should be for the idle setting. Probably need to clean where the throttle cable meets the motor as well as replacing the plug I guess?
