Idle/timing questions

I wanted to see what yall are running as far as idle speed and timing. Ill have the carb rebuilt tonight and plan to set the timing this weekend.

I have a 75cj5 with a 258, offenhouser intake, 600 cfm holly 4bbl. pretty close to sea level.

Also which do I set first idle or timing? I'm supposed to plug up the vacuum line into the distributor for setting the timing right? Sorry for the stupid questions but this will be my first experience with timing.

 

My idle is set at 700 rpm at 8* advanced timing.

Pull the distributer vacuum line and plug it. Set the timing then adjust your idle.

Don't forget to put the vacuum line back on.

 

also be sure you have ported vacuum to your advance and that it is advancing off idle(sometimes the advance might leak vacuum and not pull the advance mechanism or it is froze.)!j.m.o
a timing light is a good way to check advance,

 

found my best idle at 700 rpm and 10* btc
