I have a 1971 Mercury 500 50hp I have been working on for 2 months.
I cant get this to keep trolling speed. It runs great atanything above trolling speed. But at trolling speed I cant go more than 60 yards without pumping bulb up.
I have put kits in both carbs with floats.
I have put new fuel pump kit in twice valves and diaphram.
I have reveresed valves and inlet hoses/carb lines
New pumper. and lines and tank.
Replaced vacume lines on engine.
I even went as far as putting a different power head on with all my parts.
It has 135 psi all cylinders.
What in the heck could make it keep running out of gas at trolling speed.
This is driving me crazy.
I am running premium and 50-1 oil.
One thing ive been wondering if i pump bulb to hard gas will come out of carbs , is that right?
Any help would be much appreciated.
