I'm working on an Oliver 1850 with the Marvel Schebler USX 37 carburetor. It runs fine at idle and will take full throttle slowly while sitting in nuetral. If you try to crack the throttle open while in sixth gear it wants to breakup and stumble. I replaced the rubber diaphragm and cleaned everything to the best of my abilities. In my second photo, I have removed the back of the carb and am pointing to a passage with a screw driver. Is this a removable jet or a threaded plug? It appeared to have a straight slot with a screwdriver but it did not seem real interested in being removed. I filled the passage with brake clean and it doesn't seem to drain out of the passage. I applied shop compressed air with a rubber tipped blow nozzle but it didn't seem to take air. Is this passage #20 in the diagram below?
Any input would be appreciated.
