The SkyTec light weight starters are permanent magnet starters with a high current draw during initial cranking. I have the LASAR electronic ignition system on my RV-8 and the SkyTec light weight starter would draw down the voltage below what was needed for it to operate, making it more difficult to start. The workaround I came up with was to pull the LASAR electronic ignition system circuit breaker for the first few blades when starting, the voltage would come back up, and then I'd push in the CB for the LASAR system, allowing it to come on line for the start.
I got tired of that routine and replaced the starter with a new Hartzell starter (X-Drive). This starter was billed to have a lower current draw during initial engagement. Apparently, Hartzell bought the Kelly line of starters last year. I'm quite pleased with the new starter. I have high compression pistons (10:1) and it spins the engine quite easily, and the LASAR system stays operating during the start. I'm quite pleased with the Hartzell starter and it fits with the snorkel.

I still have the SkyTec light weight starter (it has the newer thicker flange), if someone wants to make me an offer. It has 1000 hours on it, and was working fine when it was removed.
