I have been using the search thread on this, but not finding what I want. My 47 tonner starves for fuel on hills. I have an inline electric 'primer' pump and depressing it's momentary switch brings the engine back to full power cresting the hill with ease. I use the same pump on two other flatheads with great success, so I know they flow through. Tank is red-coated, all new lines and clean clear filter. Gravity flow through filter is a solid stream. Fuel pump pressure is 3.4 psi at cranking and it fills a jelly jar/juice glass to 3/4" depth in ten seconds at cranking. Are these numbers good? Also I have tried two different rebuilt carbs with no change. Can it be the stock pump or push rod with these numbers? Thanks very much in advance.
