engine roughness

[Dale Campbell]

I had problem like yours. I have a normal asperated 337H that would run rough at low rpm and would just die out on some landings, that was 5 years ago. I took it to a old O2 mechanic
from Vietnam and he fixed my problem after having it to 3 other shops. He put a set of gauges on the fuel pump outputs and ran them back to the pilot seat to watch at differant RPM and adjusted the high and low pressure output at the pump. That solved my problem. I have flown my 337 for 5 years and all is now fine at all RPM. He worked out of Bloomsburg, Pa. the last I knew. Dale Campbell
