Sadler, They're all different but heres what I do! Mixture full and rich, prime for 5 secs, leave full and rich and crank. If hot, mixture full and rich, prime 2-3 secs, mixture pulled out. Crank until it fires and immeadiately shove mixture in. IT will take a few cranks to fire especially when hot. Some people will say to pull mixture out even when cold but I find the above works for me. A total pain in the a**e when hot. Any other probs PM me.
