I recently bought a 1998 Wolverine 350 4x4, the previous owner told me that he rebuilt the top end, bored it out .030 over, put in a hot cams stage one camshaft, and complete DG exhaust system. He did not rejet the carb. The problem I am having is that when the engine is cold it starts up fine, idles fine, and runs like hell, however, once the engine gets HOT it will not run when I hit the throttle, it bogs really bad and will stall, I can sometimes get it to run if I feather the throttle, it idles fine though until I give it gas. Once it cools down it is fine until it gets hot again. I have cleaned the carb, checked the float level and put new gas in. I was told that it needs rejetted. I took out the main jet and it is a 140 main jet, stock from my manual says 135. Oh and I also check to make sure the parking brake switch wasn't engaged. What size main should I start with. Am I missing anything else that would cause this condition. One more thing, it seems to run extremely hot just after 3-4 minutes, so hot that if I drop water on the carb intake boot (the metal side)connected to the head water will evaporate immediately. The plug color is sooty dry and black..
