I'm pretty new to small engines and I'm trying to get a Tecumseh powered lawn mower running that I got for free. Like the title says, the carb bowl isn't filling at all, and I don't know why. Here's what I know so far:
- The bowl doesn't fill at all. Even after leaving it overnight the bowl is empty in the morning.
- If I start with a full bowl, it runs fine for a minute or 2 before stalling.
- The needle valve seems to work. When I take the bowl off, fuel starts trickling out of it. When I disconnect the fuel line from the tank and spray carb cleaner into it, it comes out of the needle valve.
- The tank is vented well enough. With the tank disconnected and the fuel cap on I can pour fuel smoothly out of its outlet.
- When I move the float, the needle valve moves with it. If I lift the float, it stops the flow of fuel. If I let go of the float, it falls down with gravity and fuel starts trickling out again.
- The float doesn't have a spring. I don't know if it's supposed to have one or not.
- The float is made of plastic.
