Hi All, well I am relatively new to the hobby, may have progressed faster then my experience. I have gravitated to the Saito 4 stroke glow engines, I think they are great and they provide great realism and joy in this hobby.I have a Saito 56, 100 and two 150s My 100 has been giving me fits with the muffler coming loose all the time. It has gotten to the point that the threads in the cylinder are all wallowed out and I need to get a new cylinder. Is there a way to keep the muffler well secured to the cylinder? I have not had any problems with the 150s, mostly because I am using the stock muffler. The 100 I used a Slimline Pitts. The Pitts came loose a few times and I was never able to get it to stay. I used high temp silicone gasket sealer, red lock tight, and anything ells that was recommended. So my question is, how do you insure that the muffler does not come loose from the engine.

Thanks
