Sure !!!!! Remove the original engine and measure from the bottom edge of the mounting bolts to the bottom of the crankshaft, and measure the shaft diameter. If both engines have the same dimensions (purty likely) they will interchange. Keep in mind, no 30+year old (pre 1982) mowers had a OPC (you know--let go of the handle, it stops) so you'll have to figure out how to stop it. And never forget---EVERYTHING FITS ANYTHING IF YOU THROUGH ENOUGH MONEY AT IT!!!! Have fun.
