RE: What is this engine...........
Ive checked the internals and the Carb. bearing and liner/piston look ok, carb is working ok en sucking fuel. With the plug removed I can hear the engine sucking in fuel/air mixture. Too bad the plug adapter broke. Ill have to make a new one, no problem though--> lathe available.
After the "hit" last night and reading the operating manual for this engine, i kinda have some more respect for these engines.... these props are big !
