I have an O-360 parallel valve with dual P-mags and I've been chasing a CHT issue.
One thing I did was re-time the the PMags pet the people at emagair. After re-timing, I did a pull-through test to make sure the mags were timed together. All was well.
I also on the suggestion of a friend, did a pull through test in the REVERSE to see the results. And that's where I saw my left Pmag was firing first before the right.
Understanding that our engines only run in one direction, what could be the cause for this lag on only the right mag when doing a pull-through test in reverse?
I'm thinking of swapping the Pmags and see if the lag is still on the right side (doing the reverse pull-through test), which to me would suggest an issue (if it is an issue) in the accessory case. If the issue moves to the left, then that is inside the pmag.
Thoughts?
