Hi Ya Gents

Put your thinking caps on and help me out. I have a G26EI that until recently was running great on an RCXL ignition. Suddenly it wouldn't even start. It would and still does, hit and run a dozen revolutions or so then quits. I can continue to flip the prop and it'll pop a few times then hit and run a dozen more revs.

I decided to try the old Zenoah ignition just to see if I get the same results. I just laid the Zenoah ignition on the ground below the bird. The RCXL ignition is mounted on the firewall. I used the same 4 cell battery on both with no switches ect in the circuit. I did the following:

1. Disconnect battery to the RCXL.

2. Disconnect the RCXL's hall lead, connect the Zenoah hall lead.

3. Disconnect the RCXL's plug wire, connect the Zenoah plug wire.

4. Connect battery to Zenoah.

Flip it and it starts and runs great. Low to high RPM. Do the steps above in reverse and it spits and sputters on the RCXL. I went through this 4 times. When it was running on the Zenoah, I wiggled connections to battery and sensor but it didn't miss a beat. I bought a new RCXL ignition and have the same results.

I don't know what the hell is going on. How can it run on the inefficient Zenoah and not the efficient new one which until recently, the RCXL ran fine?
