I just purchased a new 500 Cfm Holley 2 Bbl for my 200 six popper....
Right now I'm playin with the jetting. It came with #73 jets and I automatically rejetted it to #70's thinking it would be too rich.
I cleaned the plugs and then drove it around and hammered on it a bit then when I pulled a couple of the plugs out I made the discovery that it was to lean. Plugs were basically white after driving it 15 miles.
I'm going to jump up a couple of sizes and drive it around again then recheck the plugs to see what color they are.
Am I doing this right (rejetting then driving around a few miles then checking color of plugs)??
I bought a Holley jet assortment so I have all the jets to play with.
Also I noticed that when I leaned it out (jet size) Performance dropped off a bit.
Here's a pic of it,
Hopefully it worked...
It's mounted directly on the intake (no adapter plate) and the engine is not stock in any sense of the word
It runs VER QUICK!!
