Make fast, break, repeat.
Yeah. Id say its in that area. And yes, vac is off the carb.
For the most part yes, that's ported vacuum and you don't get any until the throttle plates open. Although i've had a few engines over the years that ran better with straight vacuum to the dizzy, i don't believe that's your problem.Just for fun. I checked timing with the dist hooked up to the carb and plugged. No change.........IS that right?

As i've thought a little more, you may try straight vacuum just to see how it would effect it. Your vac. line should now be hooked to a port about 3/4 up on the metering block. There should be a port, that should be capped on the base plate and that would be straight vacuum. You could try switching them and see if you get a positive result?
You should be able to pick up a relatively cheap one at a regulation parts store and it's always good to have. Thank you for the back & forth. I'm no genius, just would like to help if i can.Ok. Vac gauge first thing tomorrow. And thanks, I love the nice clean look too. It may be for sale soon. Lol
Ok. Compression test is as follows. Going from front to back.
Cyl 1-100 psi
Cyl 2-110 psi
Cyl 3-110 psi
Cyl 4-100 psi
Cyl 5-110 psi
Cyl 6-90 psi, This is the cylinder where I was getting a lot of the popping from before I advanced the timing.
Onto the vac test next. Not really sure where I need to test it from though.
Oh boy. #6 looks like it's sick..
Ok. Off to do the vac test.Low on #6 yes, but not catastrophic. As far as the vac test, use the port on the baseplate that we talked about yesterday, if possible. If not the hose to the valve cover which is your PCV would be ok also.
Please explain? Not sure what you mean..its not ideal but 90 compared to 110 and 100 is not bad for a stock motor with unknown miles on it...
that also tells you its a stock low compression motor... so its gonna like timing...
you need to have the curve redone and go from there...
also turn that carb 90* so the primaries are one the drivers fender...
71valiant, sorry i didn't mean to abandon you. Got back to back phone calls from a few of my kids. I'll go back and get caught up
