I have a used Quadra 35. I have several questions. What oil and oil to fuel ratio do you run? What should I expect full throttle RPM to be? What sparkplug seems to work best?

In setting the carb needles, I seem to get full power but the idle is rough and is showing 2200-2300 rpm on the tach. How can I smooth the idle out and shouldn’t it be closer to 2000 rpm?

If the idle is rough and the engine stumbles a bit in transitioning to full throttle, should lean the low end needle? Or what? About how many turns out should the low and high needles be?

Obviously I am struggling. Should I set the high end for max RPM or should I get max RPM and then richen a bit?

All help will be appreciated.

Richen it slightly from maximum lean

The sweet spot rpm for high speed is around 7400 rpm. Prop accordingly normally 8" pitch

The quadra35 was my first gas engine. Ran it on Stihl oil 1:80, and a 18x8 prop. Smaller props just did not seem to pull as well.
