Have a Slick mag on one side of an O-320. EI on the other side. Mag has about
600 hours since new and never removed for inspection yet. Plugs were new a
couple hundred hours ago. They were cleaned and gapped under 100 hours ago.
RPM drop at 1800 RPM runup is only about 60 RPM.
Problem: Lately the engine almost won't run on the mag alone at low RPM and if
low enough will just die. Of course it runs fine on the EI at low RPM. And
runs fine with the mag at high RPM.
Any suggestions? Pulling the mag is my next step but grounds me for as long as
it takes to have it sent off and repaired if necessary. Just wondering about
any other ideas. Wish I had the tools to do it myself. The Service Pro, Joe Logie, from
Champion went over a spare I have (no impulse for it) in about 15 minutes at
Timing has not been checked yet.
