Lapping valves

New valve guides in place, but no grinding tool in the workshop. It took me the whole night to adjust the valve seats with coarse paste. After six hours two fine, red, full circles appeared. Time to go home and rest the palms. To morrow it is time to do the final lapping with fine paste. When I decided to replace the valves and adjust the valve seats I did not know if it was necessary. Didn´t have any idea if they were worn or not. But when I push the new parts into possition I can see the difference, and the guides are much tighter - no need to measure. The old valves were broken in all possible ways. Happy to find the reason for the lack of compression.
