This page is dedicated to engine issues. If you want to know how a P200 two stroke engine works, read my primer listed below. I have a tutorial on dropping the engine and cracking the cases to get at the cruciform. Scooterhelp.com offers a method of getting at the cruciform without dropping the engine out of the frame. Evaluate both methods and choose the one that is best for you. Before attempting these articles, read them over carefully to get a sense of how to plan them. Engines should only be cracked on a clean surface free of rocks and debris. Avoid bad weather if you are going to work outside as it will make most people rush through the job. There will be more posts as I burn more two stroke :)).
