Well, I just tried it on my install. However I must admit that I have Accusim, but for these tests selected accusim OFF. I selected "cold start" and then put the fuel selector to main tank (there's no need to turn on the emergency boost pump as there is a boost pump working in the main tank whenever it is selected), battery on, generator on, mixture full rich, magnetos both, cracked the throttle a bit open and activated the starter which means exactly:
"grab" the switch with your mouse, pull it left and then - without letting go - pull it right and hold it there. I did it five times and it worked all the time.
As for your question about AccuSim: Yes, it's worth every penny
