I have a carburetted D2G O320 Lycoming in my RV4 and while it has never been really hard to start it always takes two attempts.
There is no primer for this engine and the throttle is connected to an accelerator pump.
Cold starts, by which I mean down to about 10 degrees C up to 25 deg. I give a few pumps of the throttle, 2 to 5, then with only L mag on I run the starter and no matter wether I pump more or not at all it will not start. Stop the starter, wait 10 seconds and it will then start within 2 or 3 revs. Throttle cracked about 6 to 12mm.
I have tried running the starter, then pumping. Same as before. Trying to start without priming doesn't work.
I am just wondering what I am doing wrong.
Hot starts are dead easy, fuel on, throttle cracked, left mag and away she goes.
