I can no longer exceed 5000 rpm.
I measured the pressures in the rails:

Double-check those air and fuel pressures. They should be 80/90 (and if they are not, you'll need to address that).

tested by official mercury mechanic with original double pressure gauge. advised me to try a new compressor. Don what do you say?
Did he pinch off the air dump line to see if the compressor was capable of PRODUCING pressure?

I tried another compressor this morning. Always low pressure.
pressures remain stable after shutdown.
could it be the fuel pumps?
No. Need to get someone that has the correct tool for Air Regulator to pull it down and inspect for either a Broken Spring, OR the set-screw perforating the spring CUP.
