I believe that my float is stuck. What is the best way to remove this updraft carb? Jerry Wagner

After standing unused, the float needle sometimes stick.
Before you dismantle intakes and carb, unscrew the junction in the gas line  between the vacuum pump and the carburetor and, cautiously, blow some compressed air into the pipe to the carb.
This usually unsticks the neddle and gas flows freely, again.
Hilmar.

Hilmar, Thank you for your note. I have the opposite problem - flooding. Gas seems to pour thru the carb to the ground. I have a new float, needle, and kit. Can the carb be removed without monkeying with the intake manifold? I see in the parts list that two 7/16" bolts hold the carb to the manifolds. Is there a trick to access them? Regards, Jerry Wagner

We used to just tap them with a wrench when that happened ;D

You can remove the carb without removing the manifold. You have to use the braille method though.     Harry

When your carburetor is flooding, either the float or needle are stuck, or the float still is one of the old ones made of cork which in spite of the sealing laquer has become soaked and too heavy to float, anymore.
Use a new metal one. Check needle and seat, too.
What Harry Scott describes as the Braille method goes like this:
Take the silencer off the carburetor
Disconnect all the rods for choke etc.
Disconnect gas line
Get on a step ladder and lean far into the engine room
Feel your way to the two bolts that hold the carb to the manifold
Unscrew the bolts and take out the carb.
It really isn't too difficult to unscrew the carb and take it off.
Good luck.

I forgot to add that you have to take off the "swan neck" that holds the silencer.
The bolts are accessible from the top. If not you have to take off the distributor tower. One of the two has to come out. Too little room, else, as far as I remember.
