I just posted this question at a Q&A site, but then thought about all the experts here ...
My old 8hp Briggs engine (170702-1017-01) on my old JD mower recently lost most of its compression over a period of a few weeks (due to bad valves, I believe, since it did not use any oil or smoke), and I wonder whether I might have caused the problem. I had recently added an elbow, a 3" nipple and a second elbow to get the muffler away from a tire and underneath my mower.
Question: Does anyone here know whether 2 ells and a 3" nipple (all 3/4" pipe) between the exhaust port and the muffler on an 8hp Briggs could cause valve trouble?
I have just replaced that engine with another one (195702-4020-01), and I will leave the muffler in the exhaust port if my "extension" could cause engine trouble.
