Don't see a forum for two cycle engines, so I will try here. I am not an expert on two cycle engines. Have a Lawn Boy string trimmer when you try to start it, it acts like it is locked up. Will snap the rope handle out of your hand or break the rope. Take the spark plug out and it rolls fast and furious like the breeze. So I thought maybe carbon build up in the combustion chamber making too much compression. Basically there was none. but cleaned it all up and put it all back together. Still had same old problem. WHAT AM I MISSING. It's not fuel build up. You can pull it over several times with the plug out take a propane torch at the spark plug hole, burn any fuel out, put the plug back in and it's still the same. Grasping at straws! Thank you for your thoughts.
