Lars told me no, I had to put on the black springs and it's still coming in at right about 2250, I am going to have to shorten some springs to get it to come all in later, may play with that this weekend....

Should I rotate the plate since it has different settings or pull it off? Where is the ideal spot for all in?

The vac. can was plugged off and as I raised RPMs the mech. advance was all in at 1600....so that shouldn't have anything to do with the vacuum advance set up...RIGHT or WRONG?

Let me regroup here....after setting timeing and sitting a few days, I started up car (cold start) and it barely started running real rough with more smoke than usual (white/blueish) till it warmed up...I reset initial to 16* and mech. to 34*(thought I would try it -2*)...dropped back to idle and watch the advance as I raised RPMs and it stopped @ 34*/1600 RPMS. Is this wrong, if so what do I do next.....thanks for ya'lls patience w/me...

thanks, they came on the new dist. I'll check my old dist. to see if they are stiffer ones. should be total in at about 2800..is that about right?also the stop plate has settings of 5*-17*...what would be a good setting. I set it @ 14*...???

2500-2800 is good. The stop plate is to limit your vac advance travel. Depending on your engines vacuum and canister you may not need the plate. (you may not be getting full advance now). I would get your mechanical advance set up correctly then check how much your vac can is adding. Good luck. Dave

To slow down the advance curve, sometimes you need to make the weights a bit lighter by grinding the large ends off a bit at a time.
You have to get the advance to start a few hundred RPM faster than idle, as well. Heavier springs will help.

Kcat-fan, sorry I've been out working on mine (finishing up putting in the carpet), anyway like the others have said all in should be between 2500 - 2800. Mine is coming all in at 2250, Lars suggested to shorten one of my old springs a little and put that on to get it where I need it. I did buy a Mr. Gasket spring kit from summit (may have been Jegs), and I have the stiffest springs on (black springs), but that's still not enough. Mine runs fine as is but I'd like to get it better if I can and see if I can't get a little more performance out of it.
If I'm understanding you right you are first timing it at idle then for total, if you read Lars paper it just describes total and would make sense since you'd be changing it anyway so don't bother with initial timing just get the springs right for it coming all in between the 2500 - 2800 mark and then set total at 36

I hope the new carpet is going good, that's next on my list if I quit finding other things.

Timing is good now just when I turn up the rpms and watch it with the light, it stops advancing around 1600. I hope the ones in my old Dist. are stiffer, but if not maybe I'll try shortening the ones I have before I buy some black ones. I think mine are the medium ones (chrome looking w/ 4 1/2 loops)

The hard part, besides figuring out how it went since I didn't have carpet in it when I bought it, was taking the plunge when it came time to cut or burn a hole in it for seat belt bolts and what not, knew if I made a mistake I was screwed

GOT IT!!!
It was all in @ 1600 RPMs. I first removed the stop plate, bought advance kit by Mr. Gasket and put the stiffest spring in...it then was comming in at 1800, so I changed the weights and it's now 16*@ 800...all in 34*@ 2600....I think that's a done deal!
Ok, what's next
Thanks to all the guys that walked me through this.... I've learned alot.

I bought a vacuum advance kit from O'Rielly's for about $9. Had three sets of springs, weights, and bushings. Great deal. Apparently the Streetfire dist. came with heavy wieghts and medium springs. I learned alot though. It should help with yours too.

when I went 36* my intial was around 18* or so and spec. calls for 12* and Lars said 16*....so I put it @ 16* and when I ran up to all in it was @ 34*, so I felt that was good.
