16.5hp Briggs and Stratton opposed

Does a Briggs opposed Always sound like it has a rod knock

My old snaper with the 12 horse apposed did not have rod kock it just ate a LOT of oil. I knwe the rings were going to go but it still had enough compression.

They have a lot of mechanical noise, but rod knock sounds like rod knock. If it's knocking then you'll know.

I have 3 briggs opposed. 15hp 16hp 17.5hp and none of them knock.

I'm no expert on oppy's, but I'd imagine the camshafts in them are steel unlike modern plastic small engine cams. The sound you hear could just be valve train clatter.

Most of my flat head Briggs's are 'clattery'. It sounds a little like a rod knock but less pronounced. Your engine could just be worn out internally.

Yes, my opposed I put together for my GTR mini tractor has a knocking type noise and I even plastigauged the rods when I was putting it together. Redlinemotorsports also had a knocking in his opposed on the MTD, took the cover off and wiggled the rods without issue. I think it must be valve noise in these. Unless it gets louder or is extremely heavy/loud sounding I wouldn't worry about it.

Thanks for the help I took the heads off of it and was devastated it always smoked a little when you rev well I did a oil change and it went to knocking and smoking so bad I thought I was gonna die of inhaling so much smoke but anyway I took the heads off and both the head gaskets were blown the valve guides are wore the cylinders were scared and the piston has tons of slop in it I found all this hard to believe with it only having 150 hours on it so I'm just gonna take it off and put a Kohler magnum on it for now

Well I guess in this case something was up lol

I'll problably rebuild it one day you wouldn't know which wire on a Kohler magnum would charge the battery would you
