I have a Saito 91 and I can't keep a muffler on it. I have screwed the muffler on with teflon tape and lastly with locktight 262 - the red stuff which is supposed to hold anything. Still the muffler works loose and I am at my wits end to know what to do next. There are some special circumstances which might contribute to the problem: the pipe is 90 rather than the usual 45 degrees and I try to use a neoprene extension about 3" long. This extension won't stay on either. It seems that this engine is determined to dump its muffler and anything that's attached to it. Any ideas as to how to fix this problem?
