Just rebuilt my 1987 mercruiser quadrajet. It was a 17080565. My question is that my mixture screws (the adjusting screws on the bottom of the carb 2 of them) were at different turns out. My rebuild kit said both should be 3-4 turns out. On my old one, it ran great at idle before sitting all winter, so I wanted to use the old settings. The screw on the left (needle?) near the choke assembly was 6 turns out... The other was 3 turns out... should I reset to this setting or go with what the manual said? any help is much appreciated... also, if I get it back on the boat is it easy to monkey with? how would I adjust on the water? the screws have to be turned with needle nose as they do not have a flat head slot they are just nubs stickin out. thanks for your advice!
