Just got a power block and 720 plenum installed on my MK2. Went smooth no leaks after but my power is way down.
Seems to be making more power at 110 bar than it did at 160. This is the first impact I've played with that doesn't have the return spring in the plenum. I've even tried it with no return spring at all only pressure keeping the valve shut. Seems very timid.
New spring, 6 gram hammer weight, new hammer. Even tried an 8 gram hammer weight I have it's no better.
C1 is bottomed out around 5mm of reveal, I'm stumped. Seems to be an insanely short dwell.
