I have a Briggs verical shaft 6hp intec OHV Motor that will not start when hot. The motor runs great until I need to shut it off to refuel or move something. I have to wait about 2 hours for it to completely cool before it will start again. I have already replaced the Magnetron (gap set with bus. card), spark plug, checked the valve lash. What am I missing? This thing is about to drive me completely crazy!! The valve lash is on the top of the recommended scale, I believe it is .004 to .006. I thought maybe when it got hot the valve might be sticking open. I do not notice a difference in pull starting cold or hot. Can anyone give me some clues based on experience.
Thank you,
