My qualcast 114cc engine starts fine but after 1 to 2 minutes of running the engine is boiling hot and the exhaust is hot enough to cook an egg on, please help.

I would look at you exhaust port and muffler for clogging. Remove muffler and inspect both.clean as needed.

Have you got oil in it, is it running too lean, run it without load (chains/belts off) set the carburetor up.

Thanks, I've retuned it, put new oil in it and removed all the carbon build up from the exhaust and exhaust port
