    Was it the Sun n' Fun airshow down in Lakeland, Flordia?

    Speaking of which, I wonder which date that airshow will be open this year?

    High lift / duration cams in those old engines. Also, at lower RPM, they're loading up with fuel hence the flames coming from a short, open exhaust.

    We used to lean the BE-18 I flew by looking at the flame coming out of the stacks. Pull it back til it turns grey, then fatten it up til it turns blue again.
