So as most of you are well aware by now I had to take the Tecumseh 6 horsepower engine out of my honey's 657 because I am a crankshaft busting brute with a hammer.
Until I can locate another crankshaft I have installed a late 70s Briggs & Stratton 8 horse engine.
I was able to remove the drive pulleys from both engines and swap the Tecumseh pulley on to the Briggs & Stratton.
The Centerline of the crankshaft of the Briggs & Stratton is a little over an inch higher than on the Tecumseh. I thought I had accounted for that by moving the engine backwards towards the transmission about an eighth of an inch.
I believe that was not quite enough but it was the best I could do because of the locations of several different components.
When she puts her foot down on the brake it holds perfectly fine but the belt still spins with the engine. I may not have the belt guides in the correct position but the reason I think the belt is too short is because there's near-zero difference between brake off and clutch on.
I'll take pictures of the belt guides and try to figure out if maybe I need to move the position of them slightly.
Still, the ultimate question is -
Should I get a belt that is one or two inches or... What length...?? Longer?
