i have an os 91 fx 4 stroke to go into a spitfire
gday all.
i have an os 91 fx 4 stroke to go into a spitfire
the fuel tank is well above the center line of the carb
can anyone tell me will i need a pump to regulate fuel flow or
will exahust preasure be sufficent to maintain constant fuel flow?
i think in level flight it will run rich and inverted will be lean due to gravity
