I could use a little help here fellas. I'm rebuilding a 4hp Briggs model 100252....type 0170-01. The crankshaft has a splined end and not usable for installing a clutch. I have another 4hp Briggs model 100232....type 0254-02 with a keyed crankshaft sitting on the shelf. Can I interchange the two cranks without getting into trouble? I'll appreciate any help you can give me. Ogy
