What is the deal? My 32cc engine is acting up. It will run good for about 25 minutes, then shut down. Start it back up and it will run maybe 5 minutes. Start again and maybe 2 minutes before dying. Has a new spark plug, good 25:1 fuel mixture, both batteries, rec and trans good.Good fuel flow. So, any ideas?

Carb? Maybe air leak as you start to get hot things are expanding. When it cools down will it run again for 25min?

Tank vent?
