Ok my question is, Are there an y GASOLINE engine tuning and trouble shooting guides?
Like what syptoms occur wuth what problems and such?

My twist 150 and 26cc spe from cremarks is great but having alil odd running problem that I am not sure of.
I m breaking in, with 3 flights/ or 1 tank of fuel(20oz) running some good conventional oil from Husquavarna XLS for the first gallon at about 25-30:1 hen plan on going to my good ole KLOTZ red synthetic afterwards at 40:1

ANYWAY, my engine seems to idle great and transition good untill i get in the air and it warms up, then it seems to not want to transition as fast, not gargly or anything, actually smooth sounding just kinda boggy, then it wont quite rev out for a little bit, but still smooth sounding, eventually it does, and every seldomly it wanted to bog out when it ran wide open for a few seconds, but only once or twice out of about 15-20 min.
I know its breaking in but I dont want to touch needles till i know which way they need to go and whichone needs it. I have a lot of tuning ability with glow but gas just acts different. I know car engines well to, just these little engines are alot more finicky it seems like, and dont tell you as much whats wrong/

I think its lean, but theres alot of nice black specs of oil coming out, and the engine was very cool after flying, although, It wa 35-40 degrees out, it was still very cool, so this to me screams rich, so hais is why i dont want to touch needles yet.

but 80% of the time it responded well and has WAY more power than the 150 twist really needs, and the thing still likes to just FLOAT in.
lol after my first flight and trimming, It harrieres well, but i landed and moved cg back, and ended up likng the hariers and it was so slow, my second landing with the plane was a tailwheel first harrier landing(5-6mph head wind but still, this planes wicked stable and fun) unlike my litle twists though, it is VERY stable, locked in into hovers. almost hands off.
