I picked up a trailblazer that sparks, has good compression, and supposedly original tires (a little dry rotted), but for $200, I thought I wouldn’t be out much. The ATV set for a few years, and there was a LOT of varnish in the carb. We’re cleaning that, and then I wondered if I needed to clean the inside of the engine. I’ve not messed with a 2-stroke before, and I know I don’t want to pull the engine. Also, I was going to disable the oil pump and mix the oil directly with the gas, so should I just plug the hose from the oil pump? Finally, the clutch cover was not screwed on, and the clutch is a little rusted. It pushes in about 3/16". What exactly is the best way to clean this up?
