Working with a 1991 Mastercraft Prostar 190 with an Indmar Ford 351, Holley 4160 4bbl carb. There seems to be two problems, one of which I have solved. First problem (unsolved) is a starting problem. After sitting for a few minutes after having been run up to operating temperature for several minutes, the engine won't start without a little gas introduced down the carb barrel. Same problem when cold. The second problem was hesitation during quick acceleration of the throttle, which I have determined to be caused by zero action out of the accelerator pump. Any ideas on the first problem or are the two problems related somehow? This all comes after cleaning and rebuilding carb. Any help is much appreciated, I'm missing out on the last few weeks of waterskiing summer around here. Thanks, Pat
