Yesterday I tried to start her after a 2 week gap and had maybe 5 crank attempts before the battery gave up. I am wondering if I am doing sthg wrong as I have never been able to get the procedure quite right from cold with my new engine.
It has a red top facet fuel pump feeding a Malpassi filter king/regulator then into twin DCOE 40s. I switch ignition on for maybe 10 secs with the pump whirring, then give 1-2 pumps of the throttle, then try starting. The first I try with no throttle, the 2nd I try gradually putting in some right foot, the 3rd pushing throttle to the floor. It is very lethargic and starts to catch only after about the 4th attempt by which time I may also get some blow back (potentially lethal after reading Baz's post).
With a battery booster it jumps instantly into life, but without I do not know if I am under or over feeding the carbs with fuel.
Any ideas on a foolproof procedure?
