As the title says; What spark plug and the gap are you running on Zenoah engines.

Same as above... Although I've not operated the engine yet. :-P

Never changed the gap, also with its stock gap.

I've done a few searches and have never found what gap I should be running run so I stick with the stock gap also. I believe it's .022. Let me know if that's not correct.

My engine came with a NGK CMR7H gapped at 0.65mm / .025" I have since tried the Champion RZ7C at the same gap.
Finally the NGK CR8HIX gaped at 0.78mm /030" This plug seems to perform better,Fast starts 2 plulls,and runs smoother than all the rest.
