Snapper walk behind repower

Hello, I want to repower my old Snapper push mower. I replaced the original engine in '95 with a B&S 5hp Quantum.
My question is, what model of B&S 6.75hp engine will fit??
Thanks

Really, the only critical dimensions are those of the crank shaft. Disconnect your spark plug, drop the blade and adapter and break out a set of calipers. Then go to www.smallenginewarehouse.com and see if they have something on close out that will fit.

Snap : What the Heck did you do with the Quantum their Bullet Proof ?

Quantum still runs well but starting to smoke pretty bad. Also would like to add a bit more power as I mulch lots of leaves starting this time of year.

The Briggs powerportal has a list of repower projects that various shops have performed.

The quantum engine on a walk behind snapper was replaced with a Briggs OHV (12Q02-0025-F1). This engine has 12 cubic inches - same as the Quantum. The overhead valves increase the engine torque.

This engine has the cast iron sleeve, 25mm crankshaft and ready start. The muffler is located near the plastic chute that connects to the bag. There were no comments to indicate heat problems with the chute. The carburetor and fuel tank is located on the other side of the engine - away from the plastic chute. I don't know if this engine has an oil drain. The engine has been priced at $215.00 for repower projects.
