On my RV7 with an O-360 I have been noticing low fuel pressures on climb out.
With the electric fuel pump on I see 4 to 5 lbs which is fine but if I were to turn off the pump then I would see around 1 to 2 lbs until I leveled off then the mechanical pump will show 4 to 5.
For what it is worth I have been also noticing a slight roughness in the engine between 2300 and 2450 rpms with intermittent misses when I have leaned the mixture.
I get good idle and good climb power and it runs smooth at any setting above 2450rpm and under 2300rpm.
One last note. I have also noticed that there is a slight hesitation in engine acceleration when I push the throttle when the engine is running at 1200-1400rpm.
I might have two distinct problems here. Fuel pressure and carb problems.
Any ideas?
