OK, I misread your initial post…. I was thinking .001-.002, not .010-.020, a big difference for sure. Yes, you will need to remove the pistons to make sure there is no slop between the wrist pins and piston bores. I only mention this because on the 10hp models, where this is a big issue, there is always slop in both areas. So, when Mumbles has replaced the wrist pin bushing/bearings on those 10hp rods, I am assuming he has replaced the pistons as well…
We will have to do some investigating to see if updating the rods/wrist pin bearings to the 57 style is even a possibility, it was just a thought. I’m sure Frank will have a better idea/thoughts about this. .
