Default 1979 inline 6 mercury 115 hp

I have a 1979 mercury inline 6 115 hp. It won't start unless I spray carb cleaner into the three carbs. Then it fires right up. I checked gas lines no cracks or leaks. I pulled the gas line off on the carb side of the fuel pump and turned over the motor. Very little gas came out. Shouldn't there be a full stream of gas coming out.

Just rebuild the complete fuel system. If has good compression,no crumbling engine wiring and no exhaust cover leaks it should run like a champ.

I owned one of these old Merc inline 6's from the 60's and that thing ran like a bat outta hell.
Rebuild the fuel system and have fun.

1. there is no oil in carb spray so don't do that too much.

b. replace the fuel line, bulb and fuel filter

3. take apart the fuel pump and clean it out.

Try again,
