One thing to check is valve clearance. Many of these smaller engines wear valves and when they heat up valves do not totally close so you loose compression. Do not recall exact clearances but guessing 0.015 intake and 0.022 exhaust
Good engines have adjusters. Cheap engines adjust be removing valves and grinding valve stems to shorten them a little.

Good luck
