Jim, Ive seen different types of bowl assemblies used, some have the lil pipe with a mesh screen that goes up into the tank and other dont or they have rusted off. Heres how I check gas flow: Open the carb bowls lower drain cock plug and with the gas on a steady stream 1/16 inch or a lil larger MUST drain steady out the bottom. If not, the problem may be the needle valve n seat or the carbs side inlet strainer or upstream in the sediment bowl or tank outlet. To check that, remove the fuel inlet line to the carb and insure a strong steady stream the size of the lines ID flows, if so but NOT out the bottom bowl drain as noted above, the problems in the needle n seat or the carbs side inlet strainer. BUTTTTT if the flows weak getting to the carb, then I suspect the sediment bowl or the tank outlet. To check flow out of the tank and into the bowl, remove the sediment bowls glass bowl and turn the gas on n see if a good stream runs out to enter n fill the glass bowl, if not, then I suspect the lil tube that runs up into the tank or its mesh screen is clogged and often the lil tube n side holes out of the assembly where it turns n goes up vertically into the tank is full of gunk or rust. If flow tooooo the carb (sediment bowl n tank outlet pipe etc) is good but it fails the carb bowls bottom drain cock plug flow rest per above, the problems the needle n seat or the side inlet strainer. I suggest you remove the side inlet strainers top nut n cap (may need new gasket) and use gumout ect to clean out the side inlet strainer and its top screen and the neelde n seat is avaialble for gumout clean out in the ceter of that middle threaded tube (where top nut screws in) Nowwwww www if she passes all the flow tests above n the needle n seat is clean n not the problem, have you tried adjusting the carbs top load n idle needles and what affect do they have??? Other problem may be the carbs float level is way too low????? Does she seem to be running out of gas (flow problem or float problem see above) or is she flooding out with black smoke out the stack??? You FIRST gotta get her to pass the carb bowl bottom drain cock plug test (means tank outlet n sediment bowl n needle n seat n side strainer okay) and then look into float level problems or needle adjustemts. Theres more carb troubleshooting we could get into, but no need to do that until you first insure good gas flow to the carb (tank outlet n sediment bowl okay) and then good flow through the side inlet strainer n needle n seat so she passes the bottom drain plug cock test. MAKE SURE THE AIR CLEANER BOWL IS CLEAN AND NOT FULL OF WATER and you have fresh clean water free gas !!!!! !!!!! John T
