So I have some bad news. Was out testing it this weekend. Changed the mains to 220 and it seemed to run much better. Unfortunately, a bit of the porcelain part of the spark plug broke off and seized the motor up. Full pinned in 5th. Locked up. Just stopped running. Got it to free up after kicking it for a bit. (Shouldn’t have done that in hindsight) piston and dome are like very rough sandpaper. And the cylinder doesn’t look too hot either. Any ideas. Sorry about the poor quality. They won’t let me upload anything over 53k

No sorry, what I meant is, my timing plate is advanced +5. I also have the dynatech which advances timing based on rpm

I just meant my actual timing plate is at +5. I also have dynatech curve adjuster I guess is what you would call it. timing advances based on RPM. On curve 3 anything above 6k it’ll add an additional 3 degrees of timing. At least this is what I understand it does.

I’m having some problems with my spark plugs backing out. 10mil 465 cheetah cub on vp110 with 23cc domes 150comp, in both cylinders. Timing is advanced +5 with a dynatech timing adjuster thing. Shearer pipes. Jetting is 195 mains in 39mm carbs. Weird thing is that they only back out at the dunes at sea level. 1500ft above sea level where i live they’re fine. So idk what’s up. Any advice would help
