CARB: Mystery solved. Ron at Daytona Parts inspected the returned carb.
"Joe! Yes, we found several things with your Stromberg carb. First, NEVER, NEVER EVER use any kind of sealant around a carburetor. We found silicone or Indian Head shellac? or sealant of some sort, around the fuel inlet. There was also a piece of silicone or debris partially blocking the main jet and small brass shavings inside the fuel bowl. Photos attached."
So, yes, John used No.2 Permatex non-hardening form-a-gasket sealant, though none of it appears to have gotten inside the carb. Ron is very emphatic about not using sealant around the carb, so I pass that on.
The silicone stuck in the jet must have been in there for a very long time. Silicone is a very big no-no.
John customized the fitting to the carb so we could attach the glass bowl fuel filter directly in front of the carb. He had to drill it on the bench, but we were busted because a couple of shavings made their way to the bowl.
None of these faulty practices caused the loss of power under load, however. Ron continues:
"All that said , we also found the float drop was not set correctly preventing enough fuel getting to the bowl. That was our fault, and we offer our sincere apologies. Your carb was fully tested and is on its way back to you via UPS. Tracking info attached also. Let me know if you have any questions, and also when you receive the package.
Thank You!"
I sent a pic from the Prom and Ron write:
"PRETTY PACKARD Joe!! You will never find any recommendation using any type of sealant or lubricants around a carburetor. If you are lucky it will not cause problems; however over the years far more problems have been created by folks using sealants around carburetors. The factory's knew this and NEVER used anything involving sealant. Also, Brass fittings were only made to be used once, then discarded. Re-using brass fittings leads to leakage from stretched threads over time. In any event the carb is on its way. Let me know how it goes.
Thank You!
RON"
This advice from a top carburetor refurbishing company will be added to our best practices, despite good ole boy gasoline alley techniques.
