Well folks, this one has me stumped....

Problem: No fuel to carb. Can prime directly down carb barrel and it runs until fuel consumed. (used to run until shutoff with this procedure)

Steps taken so far:

rebuilt carb including pump diaphram.
replaced float
cleared fuel line and filter from tank to carb pump intake ok
checked hose from block to pump ok
checked venting on gas cap ok

What am I missing here? Direct prime= runs great for a minute or two.
Any suggestions would be greatly appreciated. Feel free to email me directly

sounds like the gasket on the top cover of the carburator might be the wrong one or else on there wrong be sure to line up the hole with the hole in the carburator that gives it fuel ,,,

doublechecked both ok, and hand injected fuel through input via a line and it flows into carb ok.

does it have a fuel shutoff solenoid on the bottom of the bowl?

FYI .. advised to check fuel hose around engine. Although seemed clear both ways a pressure check revealed a tiny leak which reduced the diaphram pump pressure enough to stop flow. Replace that section and bingo runs great now! Thanks for all the input though :)
