Hey guys,

I blew the 8.5hp Briggs engine on my troybilt walkbehind mower. I found a replacement Briggs L-head engine (taken off a snapper riding mower) with the same exact output shaft, but I don't know what the HP is (owner lost the starter cover). It's set up with the downdraft carb that's commonly found on these engines, and a muffler that would be pointed right at me.

Is it okay if I swap the old carb and muffler off my dead engine? Or is there a chance it won't work?

Give the model/type of both engines. more then likely the muffler will be compatible with your new one but probably not the carb.

Do you know the model number of the Snapper rider it came off of. They usually have the horse power and deck size built into the model number.

unfortuantely, no. the mower was so old it had been painted at least two times that I could tell, I couldn't find a serial number plate anywhere on it.
