Help! - How do you remove a carb?

Tim in New York · Dec 5, 2011

Apparently the carb on my 2424 needs to be rebuilt. I can't get it off the intake manifold. The nut on one side backed right off, but the nut on the other side seems to be turning the stud with it.

I've never removed a carb before. Any advice on what to do? I've tried twisting it to try to bind the stud with no luck. I assume the bolt I see sticking out of the nut is really a stud? There is no head on the bottom of the flange.

I can probably cut it with a tiny hacksaw - it did back off a bit so there is a little room around the gasket. But would that be a mistake?

Thanks!

Go ahead and let the stud come out with the nut. It is NOT a problem. Please do not twist and pry on that carburetor, unless you want to buy a new one.

It may be threaded into the flange on the carburetor. Look for a screwdriver slot at the top of the stud. Hal

Not likely you will find a screwdriver slot in a carburetor mounting stud.

If you have the electric fuel shut off needle (or what ever it's called) that screws into the carb, don't over tighten it. I rebuilt my carb and the plunger would not operate after I put it back in. Wasted hours trying to find an electrical problem when it ended up just being too tight.

Thanks, everyone for the replies. I'll give it another go tomorrow night.

Look real carefully and see what is going on.

If the stud is turning, it should be threading out of the intake manifold.

The nut may be stripped and is spinning on the stud. If that is the case you need to split the nut somehow.

before doing anything - soak the nut with penetrating oil for as much time as you can wait.

Since you said there's a small gap you could fit a hacksaw blade into, under the nut...

then what I would do is force a flat screwdriver into that gap, wedging it in hard, and try to pry up against the nut as you turn the nut with a wrench.

Sometimes that upward force can help many problems. If the stud is stripped under the nut, it will help the nut catch on the next available thread up.
If the stud is just spinning, it might help lodge it against the side and hold well enough to turn the nut.

Or, if there's enough of the stud protruding past the nut, you can hold that open end of the stud with vice-grips as you turn the nut - just be careful not to damage the threads too badly since you need to get the nut all the way off.

Thanks for the advice, everyone.

After soaking the nut and stud overnight in Blaster, I was able to wedge a screwdriver in between the flanges and put enough pressure on the nut to turn it off the stud. Turned out the stud was very badly stripped. Hopefully the carb rebuild kit contains new studs!
