I have a 2 bbl on my 289 that is running rich. I want to try dropping down the jet size. I've been skunked at all the local parts stores. Any suggestions?

Years back I bought some for my Motorcraft at my local all-pro shop, if you guys dont have all-pro's up there, then try a NAPA or a Car Quest.

Tried both, they didn't have a clue. Napa said they were the same as Holly, not true in my case.
