Settings

"My feeling is..the settings are relatively unimportant." Well I tend to disagree you need a starting point for any carb and considering the AVS is a rather rare carb for Chris Craft you don't want to just start picking stuff out of thin air.

"Float level..because the cabureretor sits at a steep angle and changes with the angle of the boat, this must be adjusted to compensate for your specific mounting conditions."
This Carb was only used on the Q motor as far as I know and it has a wedge built into the intake manifold to compensate for the angle. So the stock float setting works just fine.

"Choke stuff..again, affected by individual application."
Tim Toth would argue this one he is meticulous about setting his chokes to the exact specifications down to it being the right temperature when he does it and his motors start better than any others I have seen or heard. (ask Paul)

"Enrichment circuits..most open at 6-9" of vacuum. This means the typical marine carb is usually running kinda rich, which protects the engine and hurts the wallet. Only Holleys are easy to correct."
The metering rods used on the Carters I agree are absolutely useless on a marine motor you are always running under load. That's why I dont have them Carter got rid of them on some versions of the marine AVS.

"Accelerator pump..I always go for maximum, especially with alcohol laced fuel."
Don't like that idea at all too much fuel on the acelerator pump washes the oil off the rings and pistons meaining premature wear of moving parts and increased fuel consumption.

"Secondary opening..usually too early for marine engines. The secondaries should NOT be open at cruise."
Thats the best thing about the AVS carb extremely easy to control the openning of the secondaries a simple screw and spring system I can go to 3500 rpm and not get into the secondaries
and mine are set to the settings on the sheet.
