Idle issues when in gear

I have worked on it some today. I adjusted the timing, something I failed to do after installing the Pertronix. The timing was way off, I now have it set at 8 degrees before tdc. The distributor will not any further to set in at 5 degrees. The throttle return spring would not pull the throttle closed all the time, so I replaced the spring and reset the idle and fuel mixture, using a vacuum gauge and I have 20 degrees of vacuum in drive at idle. The needle bounces just a touch, again I am assuming a valve adjustment will help that.

I just got back from a 30 minute stop and go cruise with a small stretch of highway at 60 mph. It seems to run pretty well now and idles in gear good. I still have a slight miss that could be do to the valves needing adjustment.

Thanks for all the help and advice.

thanks for the follow-up. Too often we don't get any feedback, so there's no real resolution.
