Hi Popper, I just read the below and am wondering if theres any confusion as to what is meant by the sediment bowl??? The Sediment Bowl is the glass bowl underneath the tank, most of which, have a screw in shut off valve. Where the fuel line from the sediment bowl goes horizintal into the side of the carb, thats the carbs fuel strainer, which has a horizintal drain plug there on its side (1/8" pipe thread I think, take it out and drain and blow and clean that area out, and if you have to remove its top, you will likely need a new gasket). Fuel enters that strainer and then gets into the bowl via the needle valve seat which is open until the float level rises high enough to shut it off. Sooooo, if the carbs bowl isnt gettign a good size stream of gas continually flowing out of it, theres a restriction in either the sediment bowl area, or that side strainer needle seat/valve area, or the line. Often, the restriction is where fuel enters the sediment bowl out of the tank bottom and then turns 90 and out those 2 little horizintal side holes that fill the glass bowl. Remove the fuel line at the side of the carb where it enters the strainer, open the sed bolw valve, and there should be a good flow of gas there. If not, its the line or probably the sediment bowl intake pipe area where it goes up inside the tank or those 2 little side holes I mentioned above. Remove the glass and see what kind of flow is running into the glass area (out the lil holes) and sometinmes with mig welding wire or an air gun you can clean that out. If you do have good flow out the sed bowl and into the carb strainer but NOT out the bottom of carb bowl, the restriction is either in the needle/seat or that side strainer area. A little clean out of the sediment bowl intake pipe area will probably get you going againa and DONT ovwetighten tighten the bottom bowl nut. Ol John T Nordhoff
