Randy;
I dug around the motor parts, ect. I have here at the house and found a couple tongue mufflers that I was able to adapt (going with a radiator strap)
for the 46. I also had a new unused tube type muffler for a K&B 61 that I also adapted for the ST 61 Chrome engine.
Both mufflers work nicely and do not come lose and stay right where I got them.
Thanks for the tip on the straps.
Carl
