If you get the Promax, like I did, be SURE to flush the lines before you install them.
I don't know if it was the lower or upper line or both (I suspect lower) that had tiny steel braid clippings in it, but they wound up in the metering block.
It's bad because I thought to flush them, because I worry about, well, everything, but I had so much to do. Should someone
have to flush new fuel lines? I wouldn't think so, but yes, I did, and should have.
I went the whole week of Cruisin the Coast with the freshly rebuilt and modified Holley 2bbl carbs running poorly, and it wasn't until after I took all 3 apart and found the braid clippings in the vertical fuel fittings (I can never remember what they're called) of the center carb metering block. Once I flushed all that out, it ran fine. Look at the vertical brass fittings, some are solid, some have a tiny hole, and the braid clippings were stuck in some of those. (I'm sure someone knows what they are called)
