Jerry Woods dizzy install!

[ClickClickBoom]

Hey all,
As some on here know I have been chronicling some of my Pcar adventures/exploits.
Well as the title states I had Jerry Woods rebuild and recurve my spare distributor. There has been plenty of other folks who have done the same, but I wanted to throw my experience on the table, so to speak. I bought the car a 1975 911S Calif. Spec. Model. The woman and her husband dutifully "tuned up" the car every year, but did little else. The dizzy had some play in the shaft, so I bought a spare so I could have Jerry rebuild it. He did a fantastic job, in a timely fashion and added a couple of his own longevity mods to boot.
Well I decided to replace the dizzy today. The swap was quick and painless, the Pertronix slid right in without any drama. Static timing was close enuff to get it running. Got out the old timing light and timed it to 35deg. at 6000RPMs. Too easy!
Took it out for a drive and it ran ok, I was expecting something like a top fuel engine, but to no avail. Well crap that was a 500.00 waste. I had also gotten a Gunsons CO meter to do the F/I stuff around the same time. Well I had the mess out and making noise so what the heck, right? Got the meter warmed up and jammed it home, like a proctologist late for his tee time. Whaaaat? 7.2% CO? That can't be right, recalibrated the meter samesame.
Well here is where the story takes a twist, awhile ago I replaced all the intake rubber components and gaskets, because the previous owner never did more than the minimum tune up stuff. Well when I replaced all the gaskets, the adjustments her mechanic did to compensate for the air leaks caused the car to run so rich it almost wouldn't run.
Fast forward, because my dizzy was so worn out that at 5500-6000RPMs it ran ok except it sounded like preignition ever so faintly and at let up the noises just didn't
foster using that part of the rev range. So it was essentially a 5500 RPMs limited car.
The only way I could stop the preignition noise was to enrich the CIS mixture to the above found setting, that's where it ran best at high RPMs, I didn't have the gas tester
yet to check it.
I dialed the CO down to the FSM recommended 1.7-2.0 CO setting. Ran tons better, but had a slight part throttle rough spot at 2000RPMs. Huh WTF? Went back to basics, the car ran fine at 7.0CO, so I will do what I always do, try to give it what it wants, gave the CIS. Tweak and test drive, mucho better, little is good another is better right, well in this case yup. Sucker pulls hard as a freight train to 6200RPMs, every throttle position RPM combo runs like a sewing machine and at 6200RPMs it sounds like a wounded water buffalo on a mission, wow, the power is awesome, linear, and very nice.
I have spent the last few years fixing and upgrading the neglected mid year Pcar that no one wanted.
Thanks and mega kudos to Jerry Woods, he is a master, he spent quite a while with me quizzing me on the configuration of my car so he could recurve the advance to my situation.
Side note, go out to your cars and pull on the distributor shaft, like you are taking the rotor off, if you have any play, you need a rebuild too!

the purpose of a recurve is to get all in by 3k rpms. setting it at 6k rpms doesnt make any sense. if thats the case, id ask for my money back...

Brad,
I time at 6000RPMs out of habit. timing is all in well prior to 6K. My point to the write up is to point out the interrelationship between components/systems and how easy it is to allow creep to completely change the cars.

Hey,
Forgot to mention my final CO setting is aprox. 2.3%CO. I am running a stock 2.7CIS, w/SSIs and. Leist. 2 in 1 out(3"). What is everyone elses idle CO measurements?

Jerry wood is the man as well as other tuner men are. He knows what he is doing as well as Barry Hershon does as well as all the other Porsche specific hot rodder dudes do. hard to say who is better than who but if the car runs better thats all well, no matter who tunes it. And i'm sure, as Brad states, "It's all in at 3k".

Eric, are you talking about vertical play? as in up and down?

[Augustus]

cost of the rebuild please.

[brads911sc]

Barry Hershon (Distributor god) is $550 and that includes the recurve. Call Barry may be less if you just do the rebuild.

Jerry Woods was $450 when I checked.

Steve Weiner also does this if I recall...
