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.
submerse in carb dip overnight if it's compatible w/ carb
Rarity of some internals make me leary of the carb overnight soak--unless there's a version that isn't as caustic?
I was thinking more of something that could be applied to the mating surfaces and dissolve the crud/thin gasket.
Wonder if you could tap a shim between the mounting surface to break the corrosion. When I did the thermostat on my car I found I was the only person to attempt it and gave up the first time as the housing was stuck. On the next attempt I was able to take a spatula and tap it between the mounting surface and use a bigger and bigger one until it broke loose.
I'm hoping a razor blade isn't too thick. I did as you suggest to get the top of one carb off. Tap, shim; shim all around, get a slightly wider gap, and so forth...that worked. The bottom fuel bowls, aren't "open" to that--yet.

try it submersing in gas for a cpl days then, make sure fuel gets inside bowl, tap, tap, tap
More enthusiastic tapping with the hammer.
Well corroded together aluminum bowls can really fuse in place. It can take some substantial blows from a hammer to fracture the joint.

I just did the overnight soak in Kleen Flow dunk carb cleaner with a much rarer carb than a Zenith-Stromberg and it came out fine.
The soak carb cleaners aren't hard on the metal parts, it's other chemicals that people have been soaking carbs in that do that. Like Simple Green.

Soak in "Pine-SOL" no i'm not kidding. google it.
What stromberg model. The 97/98/48's leak so bad that a few people back in the day used to acually seal the darn things together with a epoxy.

There's Stromberg carbs, Zenith carbs and Zenith-Stromberg carbs.
All very different and all made at different times in both companies timelines.
The EE-1 family (97/98/48 carbs) are Stromberg carbs.
