I have a completely rebuilt 406 ford fe It has 3 carbs on it I would like to break it in w/ 1 carb do u think it will run too lean its an orig ford 3 carb set up w/ holly carbs.
Thanks Ray:)
 
The 406 3x2 engine is set up with progressive linkage so as long as you keep your foot out of it, it will run on just the center carb. Make all your idle mixture & idle speed adjustments on the center carb.
 
pull all spark plugs and turn engine over with the starter till you have oil pressure, or if you have the tool to prime it manually with a electric drill use it till you have oil pressure reading
 
Add a full bottle of Lucas ZDDP to the oil for breakin or you risk wiping a cam lobe or lifter. Use a good brand of oil also. Not that crappy s**t those morons on Gas Monkey used to ruin a fresh motor.
 
Make sure the carbs are fresh and in good condition. Just one carb flooding will wash the cylinders and inhibit what could normally be an easy break-in for the rings and pistons. The factory Holley 3X2 carbs are jetted correctly from the factory so having the proper fuel mixture available is not a problem assuming all three carbs are properly set in regards to idle speed and fuel mixture screws.
