Last week i was cutting down my neighbors tree for a case of beer. i had the massey 1655 and my big trailer, taking the logs back down my hill. ( steep hill and the massey crawls down her ). To make a long story short, my last trip of wood, the engine just went bang and stopped and would not start. after an hour, it started up but only one cylinder. Thinking bad spark plug, changed them out still the same. I took the breather off and tried to start and had fire shooting out of the carb. Then i noticed i was missing a screw that holds the metal breather to the carb and the other two screws where loose to. It's my fault i never used lock washers or 545 lock tight, live and learn and i hope the engine is ok.
