Hi there. Welcome to our site!

I’m a retired master technician and tech instructor with over 30 years experience. I also have access to a pretty good database on automotive service and repair. However, if you’re thinking on working on the vehicle yourself, all my knowledge and resources won’t help you if you…

… don’t have tools or the skills to use them

… don’t know there will probably be some special tools and equipment needed for a proper diagnosis

… don’t realize it may take a few back and forth replies to solve the issue

… don’t understand that I will need you to provide specific information

So, it starts and runs OK when cold but not when warm? What's missing when it's warm spark or fuel? Will it start and idle when warm if you keep spraying carb or choke cleaner down the throttle?
