Hi folks, pick yer collective brains if I may....
Picture the scene...Homebuilt aircraft coming up for annual renewal.
Bit of a mag drop on groundrun...
RPM 1200 1400 1600 1800
Carb -30 -40 -40 -45
L Mag -80 -70 -80 -80
R Mag -90 -150 -160 -130
Cleaned the plugs - no change
changed the plugs - no change
checked ignition harness - seems correctly rigged iaw Continental O-200 manual
the next steps involve stripping hoses, baffles, exhausts etc to get at the mags at the back of the engine in order to...
1) remove and test the ignition harness, then
2) remove and bench test the mags
Long shot I know but can anybody think of anything else we can check before going down this route? It looks like it's going to be expensive so I'm clutching at straws here....
