Just to enter another suggestion, exhaust valve. If the gap it small when cold that gap will get smaller as the valve expands when hot, the valves can glow 'red' hot.
Remove the valve chest cover and check gap. Personaly I would remove the valve, regrind or if necessary recut valve seat and regap. Good compression is essential for easy starting.
Good luck, Phil :smile:
