Hi Dave !
Went to try the mods.
Turned in pump screw quarter turn didn't like that, then went to half turn still no good then a full turn no good.
Went the other way,out a quarter turn it seemed to like that,had five runs no dead sticks,went great from idle to full throttle all day not a problem ,
Still smokes, but like it has a smoke system,using 22% red cool power oil.
Top end needle at 1 1/4 turns out from closed. 8,600 RPM on the ground using APC 16=12 prop
Is it still to rich,?not to keen to lean it out any more,don't want to bust the engine.

Regards RCPATTY.
