Chuck, as a long time acquaintance of gas engines I presume you have a lot of experience with hit-n-miss.

When I was a young lad we used to shear hundreds of sheep a day using a 'Coopers Little Wonder' sheep shearing plant which was powered by a hit-n-miss which if I am not mistaken was made by 'Glover'.  It was a very conventional engine of about 3HP.

With two people working the engine was at its limits and hardly 'missed' at all and it could boil the hopper in an hour or less.  My father, who owned the machine, claimed that the length of the exhaust pipe was critical and I am sure he was right as at some locations we needed a longer pipe to go out through the wall and there it really struggled.

chuck foster:
my engine needed a muffler so this is how i made it.

i started off with these pieces


i welded short pieces of round stock to the plates that make the front and back of the muffler, this was done so i could machine them to size


after the plates were machined to size i had to cut the pieces off that i had welded on to the plate. it took a while to figure out how to hold the plates in the saw.
what i did was clamp the plates in another smaller vise and then clamp the smaller vise in the vice on the saw.




i then took the round piece of pipe that makes the body of the muffler and cut notches around the edge to let the exhaust gases out


the next step was to weld a short piece of pipe into one of the end plates, it is 1" water pipe (this will screw into the exhaust port on the engine)


this next picture is just a side shot of the whole bag of scrap iron


i hope to have it finished tomorrow night and then it is on to the timing advance lever.
