You can get the static timing close enough by eyeball when you install the dizzy. I don't remember the year of your engine but I assume an SC. Make sure you are at number 1 TDC on the firing stroke (intake valve closed fully on number 1 at TDC). Install the dizzy so the rotor is pointing at number 1 plug wire. Rotate dizzy until the magnetic wheel is exactly lined up with the magnetic pickup. The spark fires when the spoke on the wheel makes it's closest approach to the sensor. This will have your timing at TDC and will be good for a starting point. You will see that you are within a couple of degrees of TDC when you finally get it started and look with a timing light.

On my 79 the toe of the rotor (the metal end) is pointed at a line on the edge of the dizzy. The heel (the fat part of the rotor) is pointed toward #1 Cyl. Keep pulling it out and putting it back until you get close. The adjuster nut should be mid point in the slot. That should be close enough. The TDC is the double line on the pulley with the #1 cyl at the top and both valves closed.
If it spits you have fire. Be careful not to pump too much gas into the cylinders or you could get a hydraulic loc and bend one of those pretty rods.

Okay, I had the dizzy 180 off. I turned it and and she fired. I need to fine tune now. I did not get a chance to adjust the timing with the light yet. She idles roughly but does not go beyond 2000 rpm for now.
Old Tee, hydraulic lock could basically happen to any motor that gets gas and does not fire, correct? Or is it something specific to a newly rebuilt motor? Regards, Aurel |

 .This is getting better and better, she now starts every time and keeps idling. Now that it is getting dark, I can see with the timing light a lot better. My advance was still far off. After dinner, she`ll be purring  .Aurel |

Congrats!!!
I cannot put into words how much I look forward to that stage..! Would you please take a video recording of the engine, and share it with us? Again -well done! I think the timing is best left for the pro's... I'm gonna let a pro get my timiing right, just to be sure...! |

Hi Otto,
I will certainly shoot a video of the engine running. I still have an issue with the tightness of the fan belt, I am missing one shim. Tonight, I thought the neighbors were gone, but they are here, and my garage is facing their bedroom, so I`ll finish up tomorrow... Ignition timing is really easy with a timing light, and cam timing is not that bad either. Aurel |

Aurel, way to go! Well done!
Post a Picture of your new motor, I'd love to see it!

I did not get a chance to finish the ignition timing this week-end, took daughter to a circus... And I am leaving on a business trip till friday. Gotta wait till next week-end now. All I can say is I liked the way it sounded: louder and franker than before. Not too much smoke too, but I am still keeping my fingers crossed on that one.
Sabeo, there are pics above in the thread. Aurel |

Yeah sorry, I didn't catch them while I was scrolling through the thread until now. That's what I get for using a Commodore 64...
  I think I should buy a new PC when I'm done with my rebuild, if there is money left of course.. LOL!

Sabeo: That brings back memories! I tried my hand a programming one of those using their samples, and decided to stick with the first version of Microsoft Flight Sim, which is what I thought the computers would actually be best suited for. That was when I lived in the heart of Silicon Valley in the 70's. My how things have changed....

Wow ! I did not know it was possible to go online with a C64, I am impressed. Hey, I still have an 86 Apple II Europlus, if you want to upgrade

As promised, here is a video of engine startup:
But, I still have to troubleshoot a few issues. First, I had a giant oil leak that thankfully was just a cam oil line not tight enough. Second, the motor sounds loud, like the muffler is not tight, but it is. Is that the new cams? Third, I have a warm startup issue. That one is bad, because I could not take it for a ride yet. Maybe I need to add a check valve to the Walbro pump. Aurel |

Hard to tell from a video, but it sounds like you've got an exhaust leak. Maybe shoot another with the camera at the back of the car....middle, toward the LH side and then toward the RH side?

Sounds like a leak. I would check the heat exchanger connections to the heads.
Good luck! |

Well, there you go, two diagnosis....one from Norway, one from S. California, both thinking you have an exhaust leak.

I agree about an exhaust leak. But for now, my problem#1 is the warm start. I cannot believe such bad luck, but it looks like my fuel accumulator is kaput too. I unscrewed the bottom, and fuel started dripping, indicating a leaking diaphragm. I hope Walbro makes a good one too...

Actually, the Bosch FA for my year is not that bad: $134.25 at our host. It is a lot more expensive for the 80-83 models. Funny thing is, a competitor lists two models for the 80 year: one at $210, and one at $105, both Bosch. Hummm, I wonder what the difference is...And they are all 3 fitting ones that can go on my car. Which one should I pick?

So, the cheapest fuel accumulator is for the turbo models (Bosch 0438170005 = 93011014000, $105). I wonder if that would be an upgrade for me or not. I assume that turbos have higher fuel pressure, and the fuel accumulator must be larger. Might work well with my Walbro high pressure pump (I just found out I have a 255 lph pump)...I feel on uncharted territory now.
