You can have a dual feed in either of those models. The only difference is the presence of a secondary metering block. One has the block, one has a metering plate. The bowls can be either style. In the begining here, you told me(and everyone else here) that what I suggested wasn't likely, now you're backing off that ? :16suspect I never said leaky throttle shafts weren't likely, I only pointed out other possibilities, based on my own 35+ years of experience with Holleys. I think I know my way around them by now.
Yes, I thought you were saying a leaky throttle shaft was not likely. Common sense says you check EVERYthing to find the source of the leak. It's hard to believe that in 35 years, you never experienced a leaky throttle shaft, but stranger things have happened.
