Our engines on this page have the following similarities. Choose the engine HP and the displacement (cc) accordingly to fit your needs:
Bolt pattern - The mounting hole pattern are the same.
The dimmension.
Muffler configuration is the same (you can reuse your old muffler)
Although spent a lot of time to carefully study about your engine, prepare, review, and compose this page to believe that your engine crankshaft size is 1" diameter x 3 5/32" length, it is still your responsibility to measure your engine crankshaft to double check if it is the same.
Other minor things that you may have to do when you buy the long block to replace your engine including but not limited to: transfer your wire harness from your old engine to the new one if it is not the same (most of these have similar wire harness though), tap/thread the mounting holes (as most of brand new engines did not have the mounting holes threaded/tapped by the manufacturer) etc..
