2150 won't run after setting please help

[kansasboy001]

I rebuilt my 2150 and it ran great for a couple days after rebuild but now the car won't run if has been sitting for a couple hours. It will run for a few seconds then die and not run again. It seems that the float is sticking in the closed position not allowing fuel into the bowel. If I beat on the carb with a screw driver or remove the airhorn it works fine.

There is also a high pitched sound comming from the carb that is only present sometimes and only on idle this has been there before the rebuild
I'm at my wits end. Please help

Mechanical pump and I do have a return line, however I have a check valve between the carb and the filter

recently fill up? had some bad gas that did that once. exact same
scenario, fresh gas "fixed it".
otherwise just grab another carb kit and replace needle. keep the other stuff for spare parts you'll need it eventually anyway.

that could be the problem its hold fuel in the line fuel gets hot and over pressurising the line and causing it to push past and flood the carb on shutdown try removing it and seeing if that helps
