I'm trying to resurrect two motors with similar fuel problems. I think they are conspiring against me. One is 1950 Fiirestone 5.0 (two cylinder) and the other is a 1961 Scotty 3.6 (one cylinder). Both have fuel tanks on top. Both tanks have been cleaned, in-line fuel filters added and the flow of fuel is fine. Both also have Tillotson carbs; the Firestone with a metal float (hinge type) and the Scotty with a cork float (no hinge) with a visible pin (out the top of the carburetor bowl cover). When the pin is extended out the top approx 1/4 inch it tells you the bowl is full. Both have had the carburetors cleaned and both motors run great but only for a minute or less. Both are not getting a continuous and adequate supply of fuel. Let them sit or tilt the motors or even squeeze the fuel lines and fuel is restored; they start, run and then run out of fuel. I've even applied pressure to the fuel tank at the fill hole. I need help from someone who's been there with these motors. Why are they starving for fuel? Do they hate me that much?
