JordB110 0 Posted April 12, 2001 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?

MPH 12 Posted April 12, 2001 Jord, you may burn your valves, How are attaching the straight pipe? Can you do a muffler the same? MPH Share this post Link to post Share on other sites
JordB110 0 Posted April 12, 2001 There are a few threads left, enough to hold a straight pipe but you can't get it tight enough to hold a muffler. Jordan Share this post Link to post Share on other sites
MPH 12 Posted April 12, 2001 Jord, my B112 has a lock on the muffler pipe, looks like a condute nut for electrical work, might look for a helly coil kit at NAPA. MPH Share this post Link to post Share on other sites
Al 6 Posted April 12, 2001 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 Share this post Link to post Share on other sites
ka9bxg 3 Posted April 12, 2001 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 Share this post Link to post Share on other sites
SimpleMan 8 Posted April 15, 2001 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 Share this post Link to post Share on other sites
