When throttling for takeoff I've been getting a stumble around 1700 RPM.
When the throttle is pushed forward normally (smooth / slow) the engine 'stumbles' for a couple seconds and then revs up normally. The engine smooths out around 1800 RPM.
If the throttle is pushed forward quickly I can almost stall the engine.
I've heard of this behaviour on the Strombergs but not Marvel Scheblers.
Is it possible the accelerator pump is injecting too much fuel? Any ideas?
thanks
