power jet

It woukd be a ton of jet size difference. I have dual feeds on alky and can probably burn a half a gallon in a 300' pass if I have them wide open. They will suck a ton of fuel thru them wide open. Single feeds would probably be close to a jet size every 1/4 turn if I had to guess.

They may have 6 turns but the first 2 or 3 turns in don't close them off much. The last turn is real finicky. Some times the difference in being rich and burning a plug strap can be 1/2 turn (on a big motor; Cubs and smaller motors more forgiving.) When I start tuning with them, I turn them in all the way, then count the turns out instead of starting out and counting in, if that makes sense.
