I got ahold of a pair of early Zenith-Stromberg carbs; in overhauling them, I've tried to remove the float bowls--puled all six bolts, and the bowls will not come off. I've tapped, used WD-40 spray carb cleaner, to "rehydrate" gaskets, but, nothing. The bowls won't come off. Is there any mild liquid that might seep into the float bowl to carb body joint/gasket that might get the bowls to release.
I don't want to use heat for fer of hurting the float bowls and internals.
Ideas? Thanks.
