Lean idle. Rich cruise.

I was wrong! Digging in again today I realize I mis spoke. Their are FIVE emulsion bleeds on each side of my blocks. 2nd from the top is a blank, all others are .028.

Idles are on top and .035.

FYI: you cannot use standard brass set screws in these blocks. They will screw all the way into the well. The damn factory bleeds have a little head on them. Picture a tiny miniature main jet. Stuck buying them from Holley. No clue which ones to block off now. What the hell were they thinking?

Use the brass that’s there. Solder the hole closed and drill it to whatever size you want.
