    I’d also look for a kink in the fuel lines, a classic as it restrains flow.

    If you have a bulb on the tank fuel line, I gather that you moved away from the pressurized tank system in favour of either a vacuum or electric fuel pump, make sure each and every connection (vacuum, fuel and electrical) is tight.

    Also run a pressure check on the fuel lines looking for pin holes and make sure all lines are of an appropriate size.

    Regards

    There are no old outboards, just machines so well built, they have outlasted their owners !
