The manual chokes are pretty straight forward. The cable isn't spring loaded so there's really no adjustment to make.

Put the carb on and run the choke cable from the cab to the carb. Push the choke cable all the way in (in the cab) and make sure the flap on the carb is all the way open. Attach the cable to the flap and you're done. Just make sure that when the **** in the cab is all the way in the flap is all the way open.

You'll have to use trial and error in using the choke. Sometimes it takes a lot and sometines it takes very little. I have a Holley 750DP on my 460 and never use the choke. But that could be because I don't have it adjusted right.

As for adjusting the idle mixtures, see my post in the BIG BLOCK forum about "tuning my 460/Holey 750". I got a lot of good advice there from guys who know what they're doing.

Good luck.
