Hi everyone, first post on this forum, I have been following for 3 years when I bought a pair of the 60 r3 engines. Love the advice and expertise on here. I have put about 30 flights on each engine and finally mounted them on my Don Smith F7FTigercat, had them running great at
6100-6200 wide open but one engine was idling about 1000rpm faster than the other so I went about adjusting them and while I was doing this one engine slowly died and quit and is being a sob to get running again. Cylinders 1&2 are running good but #3 is not firing! Only seen 26degrees c on the exhaust.
Both engines have the Morris timing ring and intakes on them.
I have tried different plugs.
Checked the valves gap and at the factory recommend gap.
Running 32 to 1 redline oil, had removed intake, tons of oil in the crankcase.
Starting to wonder about ignition system now. Have a 7.4 lithium ion battery through a switch to ignition, both sides identical.Any thoughts.
Thanks,
Raptuck
