I can't get ahold of this problem. Runs for 2-3 minutes then stalls, sounds like exhaust is coming throught the carb when it stalls. Cleaned the carb, new cdi, new coil. About 92 lbs of compression (after stalling). Removed the head (several times), both intake and exhaust valve seals are firmly attached, I even heated them with a propane torch to try to remove them and could not. I also cleaned the valveguides. Thought the head might be warped (a little) had it shaved. Could the intake valve seat be reseating itself after a breif cool down period??:-/:-/
