WD45 (Gas) Sputters

[gulag1]

Starts just fine, but once I start to drive her she struggles then sputters out. Battery seems to be fine. Could this be a bad connection that is causing a lack of power to the fuel pump? I was also going to check the manifold gaskets and dunk the carb.

A WD45 doesn't have a fuel pump it is a gravity flow fuel system. Does choking it hurt or help. If it hurts it is running to rich and you need to check your air cleaner and make sure it has good fresh oil and it isn't full of water and mud. If it helps you need to open up the main jet a bit

Sounds like the carb is not getting enough gas. Pull the drain plug on the bottom of the carb and give it a 5 count and see how the stream coming out looks like then. If it slows to a dribble you’ll have to find out where the flow is being restricted.

Sticking intake valve?

Have to ask did you do anything to the tractor before this started? Did it just start happening? That info will help.

Charged the battery last night and am going to clean the air filter today + some of the other suggestions. The only thing I did was remove the belly mower.???

I don’t know what exactly “sputters out”
means, I take it that means it dies. Usually one valve / cylinder falling out of the equation does not cause the engine to quit.

Sputters then dies. Fully charged battery, cleaned a bunch of dirt out of the air filter oil bowl, + fresh oil. Started right up and was running smoothly. Wan't able to take her for a ride as its about to storm. It sounds to me like she still doesn't have the umph that she had when I first got her, but we'll see when I'm able to drive her around. Thanks!

Once running the battery has little to nothing to do with running since the charging system should take care of all power needs. I'd pull the plugs one at a time and look them over. I fouled I'd replace them with NGK3112 plug

Thanks, old. I will try that next.

Sounds like a fuel restriction. Have the right toll ready to pull the carb drain plug and do the check used red MN suggests in post #3. You should get at least a pint in about two minutes, ideally less than that.

Cleaning out the air cleaner definitely helped, but there is still an issue. I noticed quite a bit of sediment in the bowl so I'm going to drain the tank, give it a good cleaning, clean the carb, then go from there. I'm also going to convert to 12V although I know that has nothing to do with the stalling out.

WD45 has no "fuel pump". Strictly a gravity fed system.

Gas cap vent plugged? Loosen cap and see if it runs better. Or I had a moth get in the tank of the 706. Went down into the sump of the tank and tractor died. After tractor died moth would float up and tractor would start again. Take fuel line off at carb, slip a rubber hose over line and blow backwards into tank. When I did that tractor might run fine for 10 minutes or 3 hrs. That's when I new something was in tank.
