Got it thank you so much. Sorry for using wrong terms to explain this. Like I said I can see it in my head but putting it to paper as it were is a bit harder for me.

So I can open my can all the way to the 15* it allows, as my rpms dont go high enough for the timing to be all in. My O/D and L/U make sure of that. My timing comes all in at 2200 rpm. But my cruising rpms are at 1600. I dont race this truck so I really never see 2200 rpms unless passing when I...

No I'm not talking about the mechanical advance springs, my timing is set at 22* initial and 36* all in. I'm talking about the can setting. The screw and spring inside. I was wondering if by changing that spring I could slow the rate at which the can comes in... but I dont think I can access it...

Got it, that's what I was asking.

My timing itself is set. I'm working on how much timing I can pull from my can, but was wondering if because its ported, does that mean that the vacuum signal the can receives is variable... does vacuum movement control how much advance is added. The more the blades open the more pull the can...

So I'm gonna slowly turn up my can, test and adjust until it pings at cruise. Then I will back off 2* and test... if it still sounds a little pingy I'll back off another 2* on the can and test. That should give me my full timing range. And I'll put in the medium spring (running 1 light 1 medium...

Yeah I see that.

So, hypothetically I could hit 45* maybe even 50* at cruise because of this curve and this isnt something to be to concerned about as the spark should hit sooner so that combustion burns at the right time.

This is what I thought, so a stiffer spring should act as the curve creator forcing the timing to not advance all at once. Allowing a person to set initial timing, then once accelerating more timing comes on as the motor advances in rpms and the throttle blades open up more, allowing more vacuum...

My initial and total timing are set. What I'm asking is when ported does the carb act like a computer, basically only allowing as much timing needed at on time. Since the vacuum only comes in after acceleration, does this change affect how much timing is pulled? So if you open the can wide open...

I know I can control when the timing comes completely in by putting a slightly heavier spring in. I wondering if by doing this I can slow the timing from just coming in all at once so the timing hits more of a curve... if that makes sense.

Okay, so first off I want to start this by saying I'm not asking to start an argument about which is better "ported" or "manifold". So let's not do that seen to many. My question: when ported does the motor only use the amount of advance needed? As in when the motor is pulling say 1800 rpm...

Yes

I see, I will do some more research, thank for the heads up on that.

Yes I understand that it is adjustable, I believe the one I have runs from 6* to 15*, but even at 6* and putting the distributor back to 16* I'm still back at 22* with the can. Anything higher than 22* and my vacuum signal gets super erratic. So I have to ask, can the vacuum stay consistent with...
