My 1976 7.5 only starts in the wide open position only. It screams, then when you idle it down it runs rough and will stall out if you don't keep putting back to fast. I took the carb off, everything seems ok. Was a bit of dirt in the bowl. Needle valve seems to work when float pushes up. Float will float in my bench container. Bought new tank and lines. The guy I got it from said the gas probably bad. I did soak it overnight.
Any ideas anyone.
