Just started up new from overhaul O-320 with ported cylinders and 9.5:1 pistons. One P-Mag, one Slick. Getting 100 RPM drop on either. Seems rough. And never had a drop on the EI before....
Neighbor A&P says it will smooth out as the rings seat and compression comes up. What do you think Mel, Walt, Smoky, RocketBob?
Thanks!
Taking a dinner break then will pull plugs and check timing.
