Change out ALL rubber fuel lines! The alcohol in gasoline will decompose the rubber and tiny little chunks will come loose and get into the fuel system. Many sticking floats are from tiny pieces of decomposed fuel line


Replace with a line that's alcohol & gasoline compatible.

I thought it was just me having trouble getting the starter off.
Cure is some anti-sieze when you put it back together.

Varnished carb:
Strip carb and put it in a slow cooker with pure Antifreeze ( not premix )
Simmer all day and all night stir as required...
On a serious note some of these allow carbs are sensitive to cleaners and there are rubber parts you might be worried about in others.
Ethylene Glycol has some interesting solvent properties and so do the additives they put in antifreeze to protect the inside of your engine and keep the passages clean.

This mix does a good job of gently loosening up most crude.
When you done wash in soap and water rinse and repeat as required.
I never wrecked a carb like this....

Forgot to say it , after I cleaned up corrosion with a dremal wire wheel, I put a little antisieze on the mating surfaces

As far as cleaning carbs, I just take them apart and physically clean them. Rag or steel wool the main jet needle valve and bowl if needed. Wood toothpick or copper wire to ram out the 8 tiny cross holes in the 2 jet tubes.

I find it's mostly the small jets that clog , not so much the passageways which are large cross section by comparison.

I have a NOS BGE carb part number 146-0455. This is not the same numbers you posted and I an not sure of the differances. If you can use it I will let it go cheap to a fellow stacker.
