Thanks Dallas. Is there meant to be spring with this check valve? Does anyone have a full exploded diagram of this carb? None of the carb manuals for WDO that I have seen actually show this pump check valve, they just mention it as part of disassembly/assembly routine. Other versions of WDO seem to use a check ball.
