Ugly. Rebuilding Carter / BB ETW1 carburetor with stuck pump plunger piston

[qualityhardware]

Rebuilding my ETW1 carburetor in the dis-assembly phase, and the pump plunger piston is just plain stuck in the upper housing of the carburetor.

I am at a loss for getting it out. Tried putting the whole assembly in the oven for a while and then using ice on the piston shaft to cool it to see if heat/cold would help. Nothing. Been soaking it in Kroil overnight. Nothing.

Anybody got any ideas? I am at a complete loss.

Well, I solved my own problem with judicious drilling and very light taps with a hammer. Turns out there was some rust in the cylinder wall.

Learn something new everyday. I probably would have let soak for like a month in Kroil before I got that brave.

Thanks DeuceDriver.

Got the carburetor and fuel pump rebuilt and she's running like a dream now.

Here's the rig:

Very nice rig. How come no markings on that bad boy?

Pure, unadultered laziness compounded with indecisiveness. Toying with giving it a VN guntruck paint job or making it a civilian high-angle rescue truck painted up like the old Squad 51 truck from EMERGENCY!

Did you do the rebuild or have it done and what kit did you use? I need to do mine

Thanks
