Title: Piston clerance
Post by: Kalle on 18 Mar 2016 at 18:06
Hello Douglas friends
Has started up my S6 1930 but the smoke is very blue. Piston rings and excessive wear of the cylinder is the cause. Should drilling the cylinders to + 060 with original pistons and I wonder if there is anyone who has experience of clearance, which they should have. Is it so that the rear cylinder must have bigger clerance.
Best Regards
Kalle
