In that tuneup, did you rebuild and setup the carberator properly? Add new gas since it's been sitting for years?

In addition to what Tom said check your ignition timing. Check that the vacuum advance for the distributor is working correctly as well as the centrifugal advance mechanism on the distributor. Be sure your new spark plugs are gapped correctly and the correct type. You should be using standard resistor type spark plugs. No platinum, double platinum, or iridium type. Your engine wasn't designed to run on them. HTH. -Jim

My first bet is the accelerator pump is not working properly. Also, with the I-6, it will not be a power house no matter what you do to or with it.
