I am currently restoring a little J.A.P. Model 2A and have a question about end float.
I started this project a couple of years ago, and life got in the way and I have only now got a chance to get back to it.
So it was disassembled and cleaned back in 2015, then stored until now. I have got it back together and got the little fella running, but when it runs I can actually see the crank moving in and out of the crank, and not just a little bit, probably around 6-7 mm or 1/4 of an inch. I don't remember this being present before I disassembled it.
I'm worried I've lost/forgotten to replace some shims, or washers onto the crankshaft, and this might be causing the looseness.
Question is: What is causing this end float? And how do I get rid of it?
Any ideas?
Thanks
