Jon-
* No hesitation when pulling from a stop. I really haven't noticed any acceleration problems, either from a stop or when climbing a hill.
* I don't know if this has any relevance but I use super unleaded, ~ 92 octane gasoline. I'm not using any additives, just straight pump.
* Thanks for the cold-cranking suggestion. I'll try it tonight when I get home and see how it reacts. My prediction is that there will be no change in my problem. I've done a similar approach, cranking the 6 - 8 seconds, and then pumped the accelerator pedal about 20 times. Granted, I never thought to pump the choke, but upon re-cranking, still no start. The fuel filter bowl shows filled with fuel before cranking and after.
I'll report later on what my results are when I try your suggestion. Thanks.
Bill
