ill try setting it much richer, one thing i ment to do was put another plug in, but before i could do that i crashed, minor crash, ripped off the landing gear and thanks to nylon bolts, nothing else. sanded my wing a little, and sanded down a control horn on my wing. other than that it all looks good.

im running 30% in it, same fule i used in it before when it was on my cub,
it ran great on my cub, the same guy helped me tune it before and it ran like a champ, he helped me again today because it was conking on me, he thought it was perfect, and it still did it.
so ill try going richer and another plug,

one other thing i did is i have the engine inverted, on my cap i had the holls drilled as planned for the latteral engine, i just turned the mount upside down and went with it like that, so if anything the carb is a quarter inch or so lower than it would be per plan, im hoping thats not my problem because i like it that way.

another thing, in the air, if i cut the throttle way back, it would run smooth just over idle in for a landing when i could bring it in without conking.
and ran nice just a few clicks over.

its also the same prop i was using before on my cub, 13X5.

should i try a colder plug because of the higher nitro ?
