Heading to the garage now to start the install and my main, unresolved-in-my-brain question is if i need to hook up the vacuum line that is on my current stock distributor, on the 123. |

@iankarr - Thanks for this but your original post of this text was my guide for the install. I actually called my sync profile "Ian Raby start timing" so...it's kinda your fault! (I kid...I kid...)
I've done the install, green light, load the/a curve - and that's where it goes wrong. Idle so low it barely stays running and a HUGE flat spot to the point where I can't rev it with any consistently to get a light on it. I've had zero fun with this. Something I was hoping would take 3-4 hours to do has stretched into 4 days. I'm on a plane today and will give it another swing in a couple of months when I'm back. Right now, I declare defeat. |

So, I think I recall that you changed things non-dizzy related early in this thread. I THINK I recall on of them being your throttle bypass screw. Have you tried turning the screw and seeing what that does to your idle. Its possible that one of your backfires bent or somehow altered your throttle butterfly and you are no longer getting the right amount of air bypass for idle. Are you firing on all cylinders? Does the idle pick up as the engine warms up? Have you checked all the hoses and lines? Made sure you have not blown one of them up or off during a kickback event? I used to have my car too advanced cranking and would occasionally get a kickback violent enough to open up the rubber hoses that connected the runners to the plenum. Which resulted in a runaway engine if I did not shut it down immediately. Take a step back. Look over the engine. Backfires can be damaging, see if something got knocked out of place. Zach |
