Hey everyone! I wanted to see if anyone else has experienced this issue before. It's minor but it's driving me nuts, because I can't figure out what's happening. I have a ton of small engines, mostly Briggs powered, and this season I noticed that several of my L-Head Briggs with the Float Style Carburetors (190CC usually) have been making a strange cough/backfire when running unloaded. It isn't loud enough to be backfire/afterfire, but it comes from the muffler and I have no idea what it is. You can physically feel it when holding the equipment. The carburetors are in good shape for each of the engines, I cleaned them to be sure, and the gas is new. The spark plugs should be fine. Timing is good on all of them. What gives? I recorded a few videos of different engines doing it. I just wondered if anybody else is experiencing this or knows why.
Gotta listen carefully, but it's especially noticeable on the second one
You also might notice the pressure washer has a slight rod knock. It was abused by its previous owner and I saved it just in time lol. I don't think that would affect this problem though.
