I have an 86 TRX350, The problem I am having is the valve either sticks open or shut. This is after riding for a while then I can take apart and get working again. When the problem first started I found a small nick in the carb body causing it to stick open. I smoothed it back out and then it stuck shut, I have sanded both the carb body and the slide it self with a 600 grit sand paper, it will run fine for a while then it is like it gets to hot and sticks(either open or shut). Really dont want to give up on it but this has happened way to many times including trail riding, making it a pain. So what are other options(except for the obvious replacing it) if any other. If not what is a good place to order a new/rebuilt carb for it.
