This style of gas cap has been used for years and vents through the threads. Just like caps with a hole in the top they do go bad or get plugged. I question whether the choke rod has been bent unless you have been playing with it. Finally, why are you secretive about supplying us with the model and serial numbers. Makes me think you may be in over your head and need us to bail you out. Either way it would have been a lot easier if you would help the technicians with those numbers. Wait, I’ll stop my rant about DIY guys who know more than I do.
