I have a 1994 Bayou 220, It has no power at all, I have rebuilt the carb, there was alot of junk in the bowl so I thought that might be the problem but it wasn't. Then I adjusted the valves and that did nothing. I am thinking it might be the timing but I don't know. I was told the brain box might be bad. Has anyone had that problem before and what did you do to fix it. Thanks for you time
