New a little help...
Picked up a Briggs (model # 80202), 3hp.
It has a 5/8” shaft. Need to know screw size for output shaft / clutch bolt. I can’t seem to find anything online. Any help would be greatly appreciated.
I have a feeling it’s a 1/4-28 but want to be sure. Otherwise, I’m hauling the engine to the hardware store to find out. Thanks in advance.

Check the hole with the shank of a twist drill. That should get you in the ballpark.

The minor diameter of 1/4-28 is 0.2052” and a # 76 drill is 0.200”.
I bought the cheapest drill index years ago. It has fractional, numbered, letter, and metric drill bits all in one box. Not for drilling! Use the shanks for a poor man’s pin gauge set.
Hope this helps.
