I've got 87 3.o mercruiser and it's running real rich. I've set the timing but the carb. loads up bad. My question is...the local marine dealer said it would be about 130.00 to get the dfferent carb. kits and I"M wondering if I could start with the basic gasket kit before I invested that much... I've already spent too much on this boat. It looks a 2 barrel with 1 adjustment screw.
