uploading photos, found bolt on muffler!
I found this for $4 at a small hardware shop (try true-valu or something)
MaxPower (sold at lawn mower repair shops too)
Note, you will have to buy replacement screws/allthread to make longer studs, and you may have an interference with the fins on the motor.
Edit: REMOVING ANY FIN surface on an air cooled engine is a very bad idea, and is not necessary for this modification, see next few posts for success.
(Warning: do not do this. I did not. It is not necessary) I plan to hacksaw off a little bit of the 2 fins that it touches or see if i can press in the back of the muffler a little bit. It may even just fit up after I get the new studs, hard to tell how tight the back is sitting on the motor gasket till I put a little pressure on it.
Note, the raised area on the front where the bolts come through and the nuts go down, leaves room for a matching plate (a junction box cover will work but the galvanize will burn off p u) to deflect the heat out to the sides.
Note, this works with a beach frame, but might be too close for a standard frame with motor clamped on down tube (then you could just use the stock muffler)
This muffler should not clog up because its just a box with 2 baffle plates in it and a bunch of holes drilled in the front.
Its part 4135 Maxpower, and replaces Briggs 4-8HP muffler 297274
