Thanks Bartamos...got it on the no steel, the fastener shop sells "Hardened Steel Ball Bearing Balls. E52100 Precision Alloy Steel. Grade 25. Chrome Plated.". I will stay away from them and just get the right aluminum ball, on that note...
Most kits I see do have 1 5/32 and 1 3/16 stainless steel check balls, but I have yet to find a kit that also provides the 5/32 aluminum check ball for the accelerator pump. Apparently it is not required for some Rochester B's out there so they don't include it? Go figure I have the bowl casting that requires it.
There is one old school carb rebuild shop about 30 miles from me...i'll take a trip over there tomorrow and see if they'll sell me the aluminum ball...My carb is only missing that ball. The other two check balls in different parts of the carb are there like they should be.
As far as the needle goes...with the terrible gas we have to run, especially here in California...wouldn't the new rubber tipped needles in the rebuild kits fail faster than a solid metal needle. I can see how a rubber needle would seat better, espcially if there was some crud in the fuel, but I gotta think that super dry gasl we run here would degrade that rubber over time where as the steel needle would be unaffected buy all the additives.
