123 Dizy
Forgot to mention that I have fitted a 123 electronic dizy in place of the old one. Made a huge difference. Much smoother at low speeds and no pinking under load. Better pick up all round. Having the electric power steering conversion fitted next week. Will let you know how that gets on. Now, if I could only get rid of the timeing gear clatter!

Thanks for that info.
I have wondered whether these are worth the money as it is an expensive experiment however I do have a pinking issue with the 164 (twin carbs). My other thought is to have my distributor reconditioned for which I have been quoted approx £100, but again I dont know if this would help. I have bought a new timing light and at the moment retarding the ignition one degree at a time and now at 6 BTDC with both vacuum pipes off and plugged. Better, but still pinking on load, maybe one more degree will do it! I did yesterday forget to refit the pipe from the manifold and drove with it still capped off. It seemed to pink a little less than when connected to the distributor. Can anyone tell me if this is telling me that there is something wrong inside the distributor? Is it ok to drive with it disconnected and plugged off? Jonathan |

Can't answer your question but I think that the 123 is well worth the money. They program the timing curve for regular unleaded and the specific engine.

You could be experiencing one of a number of problems there. A couple intial checks would be as follows:
If you could let me know the Bosch number, I can find out if it is possible to repair it. However, it's possible that it is too far gone. Seeing as you're having to retard the timing to stop pinking, my guess is that your springs are sprung.... This thread I did in the Amazon section might be interesting for you: http://www.volvoforums.org.uk/showthread.php?t=136261 @ Arcturus - What have you done with your old distributor? What are the last 3 numbers on the Bosch number and do you no longer have any use for it? Please?!

Thanks swedishandgerman for your response.
Just went out and had a quick look but if there are numbers on the side they are not in a position to see without taking out the distibutor but yes it does have two two pipes going to the vacuum unit. I did try to turn the rotor arm but it would only move a very small amount so I think you are correct it is jammed. I did put oil in the little capsule on the side and down the middle with the rotor arm off some weeks ago. I aasume it will have to be stripped down to unjam it? Dont know if I can do it myself but a company called H&H quoted £105 to recondition it if I cant. |

That's interesting - are you saying that you have 1 vacuum canister that has 2 pipes going into it?
You might be lucky and be able to free that in situ by putting in a load of nice thin oil into the shaft, via the felt pad underneath the rotor arm, followed by wiggling the shaft

Another way to check is to use your timing light.
You said that you set it at idle. Whilst pointing your timing light at the marks and vac unit disconnected, increase the engine speed. You should notice the timing should advance I'm not certain about the specific timing figures for your car, but maximum advance should be reached by about 2,500 - 3,000rpm where it should be at something like 30 to 35 degrees If it doesn't advance, then your advance mechanism is jammed up However, I am extremely interested in your vac unit with 2 ports. My thoughts are that you could have a unit that adjusts both advance AND retard by means of vacuum. If that's the case, then it's important that both pipes are connected to the correct port, because if you have the retard pipe connected to the advance port, then it'll pink like mad under load You sure you're unable to get me that there number? You could try using a torch and a mirror or something. It shouldn't be too obscure
