I’ve been noticing about 50% when I start my plane it starts when I give up cranking and release the key. It’s as if the act of releasing the key from start to “both” is what gets it to finally catch.
I was not sure what the issue was but was due for magneto overhaul, so I switched to dual pmags. I was expecting this to make my engine starting issues go away, but it has gotten significantly worse. I can still get it stated but almost always happens at key release after I give up. After startup everything works as expected.
Troubleshooting steps I have taken:
-Verified during cranking voltage is not dipping too low. I still see 10V on the main bus while cranking
-Started the engine with a different battery on the EI, no difference.
-probed the ignition switch (thinking maybe somehow p-leads were getting grounded in the “start” position). Everything checked out normal.
Any other ideas? It an RV-10 with IO-540-C, fuel injected.
