Default RE: pitts muffler coming loose.
ORIGINAL: thunderchicken

Hi,

I have a Bisson pitts muffler that I'm using with my Evolution 46. I'm using the same screws that I used with the Evolution muffler and they tighten just fine, but they keep coming loose. Any hints? High temperature Loctite maybe?

Thanks
Thunderchicken, I would think the threads on your Evolution .46 are metric. The threads on the Bisson are SAE unless I'm mistaken. I have several Bissons in service and I think I remember use SAE screws. If you are using a smaller metric screw in place of the SAE threaded hole in the muffler, no wonder it's coming loose.
I just checked and Bisson does drill and tap their mufflers for the screw used with the stock muffler. I must have been thinking of Slimline.
