Default Left mag stuttering ... Replace with electronic or rebuild?

So with all my cold start issues someone mentioned that maybe I have a left mag issue...
This morning getting ready to go to Taylor for their fly-in and mag check... Left mag is running very rough with the engine sputtering and unable to keep a smooth rpm. Arg!
So.. Should I just rebuild or replace with an electronic unit?
Any recommendations?

When I get to that point I think I will make the switch to electronic.

You don?t know much yet, you could have a fouled plug or just need to set you point gap in the mag.

The fastest and cheapest way to get back in the air is, of course, re-build the mag. I've had two LSE systems with an aggregate 2,600 hours on them and will use one if I build the 14. If you go LSE, I recommend either the direct crank trigger or better yet, the mini sensor.
I've easily saved the cost of the LSE's in fuel saved; it's almost 1 gallon/hour at 17.5

That is your impulse mag. You want to keep that one, and replace the right one when it is time to go electronic ign.

arg.. so I take the cowling off and what do I find? Plug lead completely off on #2 and number 4 loose by 2/3rds turn.
re-attached and put everything back together and she starts up like a champ!
Cant believe it was something sooo stupid and thankful it was cheap!

But.. I like the idea of going with one LSE on the right mag.

What is the simplest and easiest kit to install?

Default Not to derail topic

I don't mean to derail the topic but I live in Austin and didn't hear about the Taylor fly-in. Where was it posted? Thanks.

right here in VAF.

I recommend using socialflight. there is an app and you can set fly-in notifications.

Look into Robert Paisley's EFII electronic ignition before you make your decision. I'm extremely pleased with mine. His ad is on the forums here.

I have his dual setup on my -8 and I easily save over a gallon per hr. at 7,500ft
