you could use a scraper to get the high points or sand it with fine
paper until the wrist pin moves freely this is as I recall an air cooled
engine
I suggest you have them rebuilt and get the big end notched at the same
time to provide more oil to the pistons
when I rebuild the type 2 air cooled engines I hone the new cylinders to
give the pistons more room to grow. I eliminate the head gaskets and
shim the barrels
these changes come from voa as of 1990 for there rebuilt engines
also put new seats in the heads at a higher press fit so they stay in
