did you cut the end of the spring on that arm?

I did not. The only thing I did was remove the idle set screw/spring.

Looks like mine needs to go to Kole. Muffler will not stay attached to the engine. Beyond frustrated right now.
It came loose on the second flight of the day yesterday, and then [MENTION=271]Enterprise[/MENTION] spent a ton of time putting the high temp RTV gasket maker on redoing everything. Let it sit for 24 hours, then first flight of the day after 2 minutes, rattle rattle rattle.

Heads up [MENTION=2452]Limitless Aero[/MENTION], you got an engine on the way

That sounds like a huge pita.

Get some nord locks

Get some nord locks

Tried to use some, but they were too large in diameter to fit into the muffler by less than 1/2mm.

I was wrenching up the muffler after every 4th flight...Almost to the point where I was going to put some holes in the cowl to make it easy. Then go some Nord locks....Never had a problem since.

This is the part number I ordered.

I wonder if the same size would work for my 123? I've been putting off purchasing some nordlocks because I'm not sure which size OD I need and my digital caliper battery died.

Thanks Charlie, I'll give those a try after Kole and I figure out the stripped threads on the jug (courtesy of the vibrating bolt)
