Starting without using primer

[hazzer]

Hi all, 

Not posting in the bug section as I'm not 100% on this one. 

So if I shutdown the mosquito in flight I can airstart it by getting the prop to windmill and it fires up. If I keep it feathered and try start it, I get no start. 

On the ground after a flight, I have tried restarting at an airfield which doesn't have ground crew, unable to start. I tried pumping the throttle, as the engine has carbs I assumed it would pump some fuel in. Again nothing. 

Just wondering if this should be expected, or if as I am suggesting we should be able to start up by forcing some fuel in with the throttle?

On the ground, the primer pumps are manually operated in the nacelles by ground crew.  No ground crew, no primer pumping.
In the air, the spinning prop shaft operates the normal fuel pump.

So I think what you describe is expected behaviour.

I'm fairly sure carbs on Merlin engines didn't feature accelerator pumps connected directly to throttle like old automotive carbs have. Mixture regulation was done separately in them. So pumping the throttle shouldn't do anything.

Thanks for claifiying. Did wonder as the old carbed aircraft I have flown have had accelerator pumps on.
