Looking to replace an engine in a Toro personal pace mower. Present engine is B&S Model 128T02 Type 3256-B1
Code 10010858. Engine overheated and damaged valves. Drop in replacement is 128M02-0025, which requires replacing crankshaft & transfer flywheel assy.. Not a very viable option, in my opinion. Another option that may work is 126T07-0332. It has the same crankshaft as the original engine. Would that work or do you have any other suggestions for a replacement? Seems the biggest problem is the stepped crankshaft with external threads. What about going with an engine and changing the way the blade bolts on? This is for a customer and I am looking for the best possible options other than buying a new mower.
