Just feed it as fuel through the carbs. Dissolves stubborn dried out gas residue really fast. I break the fuel line under the drivers footwell area and feed the carbs from a quart can. Let the carbs sit and soak for twenty minutes and restart. The engine runs just fine on the laquer thinner.

I originally went with this years ago as the idle passages where not flowing..The ideal of removing soaking and kitting the carbs left something to be desired as well as disturbing the base gaskets.

Worked out fine. It may not cure your problem but it will clean up those internal carb passages. Any major difference in them running after cleaning was the residue removal.

Right now you have no real ideal of whats in or not in those carbs. When these carbs sit around unused the gas dries out and the reidue is not easily put into solution again with just gasoline.
