This one is probably one for Restorob. I have a Snapper 21 6-speed, model P217017BVE. I got to looking at the crank today and it's either 1" or 25 mm dia. at the stub shaft. I don't have an accurate caliper. It's a Briggs 7hp Intek 128602 0149 E1. The reason I'm interested in the dia. and length of the stub shaft is I want to replace it with a Kawi or a Honda. I like the mower but not the Briggs engine. I got the crank part no. as 691456 at the B&S site but couldn't find any dimensional drawings on it. Can you help Restorob?
