I have a 76 searay SRV 220 with a Ford 302 and mercruiser 888, with a two barrell carb made by Rodchester. My boat runs great except wheh i slow the boat down and try to put in neteraul or under 5mph the engine stalls. The boat stars up after a couple rotations of the motor and will idle ok after that. I adjusted the choke but because of the change in temp when the motor gets warm, the choke is either too lose, or too tight when cold. Do i need to adjust the fuel mixture, or did my fuel pump take a crap. Thank you very much for your help.
