Come on guys!
Doesn't anybody know anything about these RB motors.
This engine is really getting to me.
Its going to end up an expensive paper weight very soon.

Its just won't run any longer than 1/4 of a tank.
Lean it, richen it high speed, low speed nothing seems to work. It does the opposite to everything i would thing, richen it and it gets hotter, leaning it doesn't help, still cuts out, and there is plenty of smoke.

Again, only ever had a problem with this motor and a collari. Have several Nova Rossi's and OS motors and they never miss a beat
