I got a Tower .75 on an Uproar 60 that I haven't flown.
Here is the problem: The muffler kept rotating around the screw that holds the three pieces together. Since I didn't have any locktite or a matching nut to double nut the thing I put a drop of solder on it to secure it from coming loose.......But the muffler STILL rotates.
Is There a means to permanently weld the pieces together.. I can Arc Weld And Solder , But I dont braise.
How about JB Weld?
1 more thing anybody got a fix to quiet this sucker down. I thought about a Bisson Muffler but I don't want to spend 40 bucks on it unless I have to and I know it will quiet it down. I have a Husqvarna chain saw with a 70 cc
engine and I swear it ( the tower .75) was louder, the muffler worked its way off once before I soldered it and and I almost couldn't tell the difference..
I don't mind loosing a few rpms for some for a few decibals. It needs to lose about 20.(guessing).
