Re: fuel and carb question

I don't know what we're working on, but I'll try. If it's a mechanical fuel pump test for 4-5 lbs of fuel pressure but also check for fuel volume it should pump 8 oz of fuel right now. enough to fill your carb bowls in a minute or 2 of cranking. Try drawing fuel at the pump inlet to check for sucking air or collapsed rubber fuel line. I would hold off on scraping the paint off for now.
