RE: Prop Nut Loosens
Bax:Another day and another frustrating attempt to start this engine. I switched to a wooden prop, put abrasive drywall grid washers on both sides of the prop, am not using a spinner so no backing plate, tightened the nut as tight as possible, AND even with just a small squirt of fuel into the carb and NO glow igniter, I flipped the prop over a few times and the nut loosened.
I then retightened the nut, finger over the carb and turned prop over to prime the fuel line, put a small amount of fuel into the carb, and then tried to flip backwards. Would get a small pop but no indication it wanted to run either direction.
I even cut small hatch marks on both sides of the prop hub to try and get more grip on the washer/nut. What is next???
