Nothing to keep fuel from getting from carb to engine unless an intake valve is stuck open, or exhaust is blocked keeping it from drawing air through intake. Pull the drain plug form the bottom of the carb and see if you are actually getting fuel into carb bowl. Could have a stuck float valve, or the screen behind the fuel line fitting in the carb plugged. Might also be dirt blocking metering jets in the carb. These old gas tanks have had a lot of years to accumulate dirt and rust.

You said the fuel is getting TO the carburetor. Have you checked that it is getting FROM the carburetor? There are a number of reasons why a carburetor won't deliver fuel.

For starters:

1. clogged inlet screen.
2. stuck float/needle.
3. vacuum leak.
4. stuck intake valve.
5. clogged jets.

THE CARB GETS FULL OF FUEL

BUT THE PLUG IS NOT WET
I AM VERY STUMPED

YOU GUYS ARE A HUGE HELP THOUGH WITH ALL OF YOUR KNOWLEDGE

Compression check - even finger in plug hole to see if there is pressure/compression on all four cylinders . Ignition - see if the Cub is firing at the plugs. Carb kit or disassemble and clean to solve the flooding problem.

Is this a sudden problem or has the Cub's performance slowly been going down hill for a while?

will the engine fire with a sniff of starting fluid? divide and conquer

Remove the air intake hose from the carb and spray some starting fluid through the intake as you are cranking. If it starts and runs while spraying fluid, you have a carb problem.

cfrost5: Please keep us posted concerning progess in solving your problem. I am experiencing the same problem with my Cub. Plenty of gas in the carb with the cylinders receiving little, or more likely, none. Thanks, Dan

You might also check the manifold gaskets between it and the block, and the manifold itself for vacuum leaks. Be sure the gasket between the manifold and carb is air tight and not letting ambient air draw though there.

Good luck!

Chris

It may be better than a comedy show but clogged carb is the most likely problem since it happened all of a sudden. Yes many electrical problems could have the same look but the most common is plugged carb.
