I hear ya about the temp gauge, I bought it after I could not figure out why this thing would run great on the ground, but then slow down and lose power after 3-4 min in the air.

Any richer on the needle, and the plane will not takeoff!

I tightened the head bolts

I run 15% nitro 20% 100%syn oil

I bought it used, and it has a swept bact after market pipe on it

thanks
