Mornin Terry, That brass slotted adjustment in the bootm center of the carbs bowl is the main load fuel adjustment, and screwing it in LESSESNS or leans the fuel/air mixture, OUT would give her more fuel. However, you say you arent gettign fuel to the carb?? You have to first supply sufficient gas flow into the carbs lower bowl to fill it and its float level be properly maintained (by the float and needle valve and seat operation) before that metering screw is gonna make any difference. AFTER connecting to the carb, gas has to flow UNRESTRICTED through the inlet strainer, then the needle valve and seat, to fill the bowl until the float rises and shuts it off. 1) If you can open or remove the carb bowls lower fuel drain and have the gas on as described below (depending on if you have the safety shut off or regular sediment bowl), the needle valve and seat (if working and NOT restricted or the inlet strainer restricted) should allow a continuous (2 to 3 mins to be sure) gas flow out the carbs bottom approx 1/16 inch diameter. The fuel inlet strainer, right where the gas line connects to the carb, can be restricted not allowing good flow into the needle valve and seat. IF NOT, check the fuel delivery gettign to the carb as described below: 2) Remove the fuel line from the carb and see if its running a good solid stream of gas the size of the lines ID first. If it has the fuel sediment bowl assembly with the diaphragms and small oil lines to it, you have the safety low oil pressure gas shut off which turns the gas off if theres low or no oil pressure. If it has that, unscrew the lil knurled nut on its top and depress it then see if the gas flow to the carb is as described above. Regardless if its a regular sediment bowl or a safety shut off type, with the gas on (valve on regular bowl, or button down on safety type) remove the glass bowl and see if theres a good gas stream running out the lil pipe to fill the glass bowl. If NOT, there may be a restriction up inside the tanks inlet pipe or mesh screen if it has one. 3) You have to get ample gas out the sediment bowl and through the line, then through the carbs inlet strainer, then through the needle valve and seat float assembly to keep the lower bowl full before shes gonna run right. Good Luck, Ol John T Nordhoff
