It should be easy to see if the full crank side pull originally had the small module standard as the small module has one hole but the
earlier module has 2 holes so if the full crank has 2 holes in the alloy it originally had the old big module.
I know all the 1983 Super Starts were still using the old big module.

Hi maxwestern, here's a pic I took of the mower and of underneath showing there are two holes, one holding a small module on top. The large one must have been replaced in the past with a small one underneath riveted in using one of the holes before that failed also. Maybe that's why the mower fit put into prolonged storage before I saved it from going to land fill and replacing it myself, getting the mower operational again.
