timing / tuning question

Got my '66 started this past weekend after 3 years in hibernation.

Runs OK, but I am having trouble getting the idle down. What RPM should it be ideling at? I know need to time the ignition and tune the carb. What order should I work in? What should my inital advance be (At idle) and what total advance should I be shooting for? I assume with the new cam etc. I will not be at factory specs. Should I disconnect the vacuum kickdown on the trans. before I set the carb?

I also have an intermittant miss on one side that I only notice at idle. I am going to check the plugs and wires. Anything else that could be causing this?

Thanks in advance.

Engine was rebuilt a little over 3 years ago. Didn't drive it much because I had some reliability/driveability problems that I thought at the time may be caused by an old fuel system and the A/C. Had to put it away and now I am trying again. I broke the cam in as was directed at the time. (forget what that was now) Engine probably has less than 1-2000 miles on it.

New Gas. New Tank. New fuel line to pump. Cleaned a relatively new Carter HP fuel pump. New line from the pump to carb w/ new filter. Cleaned relatively new Edelbrock Carb and replaced gaskets. Car starts easily, but it just seems to want to idle around 1000 rpm so that it doesn't stall when I put it into gear. Seems a bit fast to me seems like it is hard on the tranny to pop it into gear that fast. I bought an idle compensator solenoid to help with the A/C this time around, but I haven't got that far yet.

Cam specs? Edelbrock performer cam
Carb? Edelbrock Performer 600CFM 4V
Heads? Stock - Had them re-built with the engine, but nothing drastic.
Don't believe there was much done to the engine beyond stock replacements to effect compression.
Headers? Yes - Hedman or Hooker, I believe. They have been on the car long before the rebuild.
Mechanical advance distributor. (Mallory Unilight)

As far as the miss goes I can just hear it out of the exhaust when standing in the back. Random intervals and only on one side. Probably need to check my wires again and clean and regap my plugs. this is minor and may work itself out after it has a chance to see the road. EDIT: I had the valves adjusted once I got it running the first time. Maybe I should do it again? How often should they need to be adjusted right after a rebuild? Maybe something slipped in one cyl. causing a miss?

On my Edelbrock carb I have three vacuum ports on the front of the carb. Two small on either side of a larger one. The larger one is connected to the PCV valve. Are both of the smaller ones manifold vacuum? I checked it on the drivers side and am pulling close to 15"

I did time and adjust it last night. Runs much better and idles around 800-850 and no longer dies when I put it in gear. Thanks.

Next problem.... the miss I thought was just one one side is really just the engine bogging at idle. with the timing light it looks like it jumps the advance 10+ deg. and then returns. Could this be a vacuum leak in the intake? I have a mech. advance distributor.
