(IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) I just got my fuel pump TODAY and I will be starting the SIX up ASAP. I would like to here some tip/thoughts on;
- How long should I run it
- What RPM

I installed new rings, had some top end work done, rebuilt the webers..etc

I am hoping it will fire right up but who knows? The carbs are more then likely not dialed in but should be close, timing will be close (I set it at TDC).

Once it is started should I immediately start tuning it? Timing and then the carbs? (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif)

Should I stop it to check the plug color to make sure I am not running too lean/rich?

Cheers (IMG:http://www.914world.com/bbs2/html/emoticons/driving.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/driving.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/driving.gif)

Just my $.02 so don't take this as gospel.

This is what I did:
-have an oil temp guage.
-start it and run for 20 minutes or until aroune 200F (which ever comes first)
-we then changed the oil
-then let it fully cool overnight.
-start a 2nd time for 1hour
-change the oil, do the valves, and let if fully cool/cure again.
-Then drive it 500 miles and oil/valves one last time

You will have to set the rough timing right away, but when its tight and cold you can't do the carbs much anyways.

we were told to follow this for a new motor.
you may not have to go to such extremes on a top end job, although I was surprised at how much debris was in the oil filter at the very first change.

Even if you didn't do the valves and the oil as often, I would do the valves once at a minimum and go ahead and change the filter for safety sake at least once.

I was told that the 20minute/1hour steps with full cool down inbetween allowed for thermal heat cycle of the motor and was an important step.

I think also remember to heat cycle it every time you start it for the first few times you run it if nothing else. (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif)

That chopstick thing was classic. (IMG:http://www.914world.com/bbs2/html/emoticons/clap.gif)

Good thing I wasn't eating or drinking.

This is exciting to hear that you are ready to start the SIX. Good going.

Are they new cams?

If so you need to run it at 2000 rpm for about 20 mins, to break in the cams/rockers.

If they are the old cams being reused, just start it let it warm up and tune away

Thanks... I am using the old cams that still ooked okay.

The hard part is stopping myself from running out there and firing that bad boy up...

I need to run through my check list and make sure the wiring is okay..

Maybe tomorrow night. (IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif)

I should have my back-yard test run station wired tonight

Are the cloth braided vacuum hoses the same hoses used for fuel?

I have some new cloth braided hoses and would like to use it for the fuel lines from the fire wall connections to the carbs, if possible (IMG:http://www.914world.com/bbs2/html/emoticons/unsure.gif)

Okay the crane stuff doesn't seem to be working too well for me (IMG:http://www.914world.com/bbs2/html/emoticons/headbang.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/headbang.gif)

I had to give up last night after I had enough crap come up.(IMG:http://www.914world.com/bbs2/html/emoticons/headbang.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/headbang.gif).

I am running a Crane ignition system (Hi-6, PS-91, and a XR 700). I printed out the instructions today and will double check, for the 5th time) the connections.

The engine does crank over but as soon as I turn the ACC on...magic smoke appeared from the Hi-6. I saw the smoke very quickly and turned the ACC off. I have no idea if things are toast right now. I'll find out tonight...It's going to be a long day at work waiting.

ALSO, the cam oil feed lines are leaking at the connection to the cam tower. Are two washers used or one? I have the banjo fitting sandwiched with two washers

cheers

The HI-6 is toast.
I took it apart and part of the board is fired. Looks to be related to the (-) from the coil.

I am 100% sure the system was connected correctly Black is (-) and orange (+). I am using a crane PS-91 coil, well I was.

I guess that's what I get for buying USED electronics. It could have been the coil or the Hi-6. I bought all pieces from the same guy?

$200 down the drain and now I need to buy a new one....These conversions fun (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif).

Can I just plug in a OEM CD unit, just to get this engine fired up? I would like to keep the XR-700.

Cheers

The xr700 can be used to fire the stock CD box, getting a good tach signal is a toughy, I had the crane nee Allison xr700 box in my 911 in 1985 or so so its been a longgggg time since I wired it up.. that car is long gone (IMG:http://www.914world.com/bbs2/html/emoticons/laugh.gif)


I also had Hi6 PS91 and xr700 firing my 911 about 4 years ago.. I rmember it was a pretty straight install.. but I needed the crane tach adapter


again I dont recall the wiring sequence..

sorry to many lost neurons.

The wiring wasn't too bad. That is why I am unsure why the ground connectoin/wire would have heated up some much.

I will call Crane on Monday to see if there is a way I can test the PS-91 coil?

I almost feel like (IMG:http://www.914world.com/bbs2/html/emoticons/icon8.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/barf.gif)

hey man dont sweat it! I had the same problem, crank crank, leak, no fire etc...now im smiling every time i start it!!!

xr700- make sure you got the optic set up all the way, set to TDC, see if the light on the box is lit. set towards the early side of the slot....like, if it turns ccw, set it as far clockwise as possible till light goes off, then back ccw till it lights again. Just a tip that i didnt quite get from the instructions.

Thanks..

I tested the XR 700 signal and it is there (Connected a test light to the yellow wire and it flashes my test light).

The power light on the Hi-6 lights but it doesn't blink. It should blink when the signal from the XR 700 is received....Mine doesn't blink and I get no spark. Seems like the HI-6 isn't making use of the signal

I don't think the XR 700 has a light on it??? I'll need to take a look.



Thanks again :beer1
