I am trying to find a carb rebuild kit for my 1993 Larson 170. It has a 4.3 V6 Mercruiser with engine s/n 0F074116. The engine is stamped GM 14097289. If there is a number on the carb itself, I have been unable to find it but it is a 2 bbl. I am hoping the engine s/n is enough. The boat runs pretty good but hesitates upon full throttle which makes it tough to pull up an adult on one ski. I have replaced plugs, wires, cap, rotor, and fuel filters. Any help is appreciated. Thanks in advance. Jeff
