6hp. evinrude 1973 fisherman. just not getting out of it what i think i should. after going over it I decided to rebuild carb. with that done its better but not what it should be. during rebuild I realized that the carb I was rebuilding matched that of the 2hp. colt junior and 4hp.<br />except no high speed needle jet! theorfice in bowl is plugged with washer and bolt. and my housing cover does have a hole for high speed jet.is this the right carb for my motor? should it have high speed jet? is it sufficient for my motor? many thanks.
