Filled with fresh gas. Car started relatively easily after gas worked its way up to the carb. Checked again and timing is at 6 BTDC. Car is running rough. Hooked up tach and set RPM to 450. Car still shaking. Played with the carb screws and got the idle a little smoother, but not like a Packard should be. Still hesitates when I give it gas. A couple of revs and a rather loud backfire later and I was done for the day. A couple of inches of snow indicate I will not be working on the car very much longer this season.

So I have:

Rebuilt the carb
Installed a rebuilt fuel pump
Rebuilt the distributor with new points and condenser
Rewired the car (at least the front half)
Installed a good ignition switch

The result is a car that still hesitates pretty bad when given gas and a rough idle.

I guess I am not very good at tuning engines!

I also still have the tapping noise. Maybe that is causing all of the issues?

I want to hook up a vacuum gauge to tune the carb, but if you are not supposed to use the port that goes to the distributor, where do you hook it up?

I'm wondering if I have a manifold leak.
