hi ya the most common cause of a stuck float in my opinion is wen the carb has had crapy fuel in it {a tank with rust in it} which then has passed into the carb and around the throttle float and as we all know like with the piston in the head when its got crap in for some bizzare reason it will score the bore and pit it well this is the same thing the fine rust that does manage to get through the filter on top of the fuel tap it goes behind the float and scores the inside of the carb where the float sits and slides up and down which iturn makes it stick my suggestion would be eiter buy a new slide and get a fine bit of sand paper an lightly sand the inside where the slide sits and you can also lightly rub down the float but carefully bit by bit and keep puting it in the top of carb where it sits to makesure you dont over do it if your too tight to spend few quid on a new slide lol
Usually a stuck float mechanism.
A bad, stuck or dirty float needle inside the carburetor.
The float could be stuck because of stuck needle valve, or rust. The float could also be leaking and be full of fuel.
More than likely, the fuel bowl float is stuck in the open position.
your float is stuck in the carburetor. Clean it with carb cleaner.
Bad sensor, stuck float, bad connection somewhere between the sensor and the ECM.
There is a magnetic float inside the washer fluid tank that causes a magnetic sensor on the outside of the tank to activate when the fluid is low. Either the sensor is bad or the float is stuck.
The carburretor float valve is stuck open or the float is punctured/stuck down.
Float stuck open
the float is stuck open or needs adjusted down.
The float is stuck. Try a fuel cleaner or additive.
You probably have a stuck float or the carb is out of adjustment or choke is stuck on. hope this helps
