    To remove rust, would you recommend removing the cylinder block cover and polishing (with pistons still in and protected) or would I be completely disassembling?

    Also, can I replace the top and bottom oil seals without complete disassembly of crankcase?  Seems like yes if I read the service manual and replace the oil seals carefully.

    Also I see that the points on the bottom cylinder open only to 0.012 in… not 0.018 in as recommended… need adjustment (and cleaning). That could cause weak spark. I do not see pitting or wear on the points, I think they are OK.
