He'll know.

Hi

 

 

This is an extract from an old copied manual I got a few years ago. looking at the bottom of page 38 though, that's a heck of a gap.

 

Hope it helps though.

Hi szymon

 

Just sent them. Still think that's a wide gap, so might be worth getting a second opinion.

thank's for the pics. no info about the piston ring gap. i think its +/- 0,2 mm but not sure. at my set is like a ONE mm!

3 to 4 thou per "1 of bore sorry .004"is about 0.1 mm think
