My petrol converted OS fs120 has run fine for 10 flights or more but suddenly stopped and dead stick landed heavily and was damaged bad.
I repaired it and the motor that previously ran perfectly will not run. I can get it to fire and run by choking the carb with my finger but it stops with the choke off.
I have changed the diaphram and pump membrane and checked every thing. It seems to be starving for fuel so I was thinking of raising the arm on the fuel regulator to allow more fuel.
The arm is at the correct height using a gauge but the arm has some slop in the needle and lost movement.
Any suggestions or thoughts on how to fix this .
