Runnning without muffler

Recommended Posts

JordB110
The threads on my B-112 are pretty much shot where the muffler screws in so I'll probably just run a straight pipe out the side of the engine. Will this hurt anything(besides the neighbors ears), I have earmuffs. :o) The reason that I am asking is because there will be a lack of back-pressure. Will I need to make any carb adjustments? Thanks,Jordan

Hi, Years ago they used to say this was a problem with no pipe, but with a little pipe any air that gets to the valves right after shut off is warm anyway. It is no longer considered damaging. My only caution is your hearing, I ran a 16 2 days with about a 14 inch vertical straight pipe. It sounded mean and I liked the bark. Two days, I damaged my hearing a lot and it has never come back. That was in the late 60s. Good luck, Al

simply turn a short pipe into the block with a small can muffler on it and make a simple bracket to the grill and weld it to the pipe you should have some threads in there and if not try running a tap in the hole The noise comming out of that engine is way to loud for me even a small muffler will help some.Bob

I would never run a straight pipe, the loss of hearing the occurs is too great, I have found out the hard way,..., I ran a International 100 hydro tractor that had a turbo with no cab, pulled a wagon with it a few days a week for a month for harvest time, I did this for 2 years, in school we have hearing tests and I have lost a considerable amount of hearing already, I also ran a straight pipe on my B-112 when I had to mow the grass, the muffler fell off and even with earplugs, I still couldn't take the noise, I am 15 and one of my teachers who is 60 years old has more hearing left than I do, not a good thing, PLEASE do your self a favor, DO NOT RUN A STRIGHT PIPE! Hearing is a good sense to have, and I would like to have mine whn I am old. Thank you, and have a nice day,-BradW
