thanks guys... one more question, how are the secondary metering plates sized? say in this case, the 134-39 metering plate would be equivalent to what size jet if a proper secondary metering block was used?

first off, a good rebuild kit would solve most of your problems, probably has a blown power valve also (part of a rebuild kit). next, a new vacuum secondary diaphram and spring kit would probably cure the boggs/stumbles.
