Need Help in Atlanta

[PCHunt]

I'm having an unusual mag problem. Plane currently at KFTY (Charlie Brown) in the Atlanta area. I am on a long trip out of San Diego!!

The mag runs great when cold, and when airborne, but just after landing the engine runs rough, and when I do a mag check, the right mag runs extremely rough, and the engine dies. Two hours later, (After cooling off?) running good again.

I'm having my spare mag shipped overnight to arrive this afternoon, Wed 4 Nov. I have a few tools, but could use a mag timer box, etc.

The mag is a Slick 4370, non-impulse. My spare is a 4371, with impulse, so not sure it will fit.

I could fly to another airport in the area, if that would help. If anyone has a 4370 that I could borrow until getting home to San Diego, that would work, also. Or maybe there is a good mag shop in the area?

If anyone can help, please call my cell: 858-395-7383.

Thanks...

I am up at Cartersville (VPC) and have tools and a timing box. I don't have a mag but I'll keep looking.

No it won't fit, just like that... IC mags need a different gear, a spacer, and longer studs... so I think, unfortunately, you ordered a wrong thing..

Aircraft Spruce isn't that far away.. you could probably drive down and have a correct mag in hand today..

[Sid Lambert]

OK VAF gurus.

I'm thinking he can take the gear and spacer of his 4370 and put them on the 4371, thus removing the impulse coupling and that will work fine. Is my logic flawed?

Or he could just order a P-mag and be done with that antique mag thing.

Pete, it sounds like your old mag has a crack that expands when it gets hot, impacting your timing.

Good luck with the repair.

You are very close to Aircraft Spruce at KFFC. They are on field and have parts right there.

No, mags with an impulse coupler have a longer shaft.

You could fly there and I believe there are some RV builders on the field there also. There is at least one RV-10 builder there.
