Anybody know the answer to this. 3 yr old 20 hp Honda, runs great, starts well cold, but after a few minutes running... ie partly warmed... it takes maybe 8 + pulls to start. Tried varoius comb.s of choke cannot seem to solve it. Buddy with 9.9 Honda has similar prob.Must be some trick to it I guess. Cold it seems to do best with a couple of throttle pumps then full choke and goes 1 or 2 pulls. Help.....

With the limited info given, I 'dd be willing to bet you are lugging this unit.What is your geography?Do you have access to a shop tach to make sure your idle is correctly set or that that dealer you bought this unit from set it properly?Sounds to me like your idle is set WAY too slow.
