| Post subject: | My ignition timing is all over the place... |
I tried setting the timing today to 2.5 deg BTDC as per factory but the mark was running all over I.e. Very unstable. I set the thing the best I can and took a long drive, after about 50 miles of driving the engine start pinking badly at anything above 1/3 throttle. I suspect the timing went crazy and advanced by itself. What could cause this? The spring inside the distributor? Is it hard to take the distributor out? Thanks Syed |

Timing chain/gears need replaced. Worn out. Dennis |

I've got brand new chain and new harmonic damper. So I don't think its the chain.

Your points need sharpening (replacing). Its easy to get the distributor out..... Some people have problems putting it back. |

While the distributor is out, clean and lubricate the mechanical advance mechanism. The 40 year old grease on the advance weights and guide plate can harden and get sticky and can make the mechanical advance mechanism stick and not operate smoothly. |

Do yourself a favor, get rid of the points, get Pertronix. Easy to install, looks stock, don't gotta jack with it. I might have one around here from my brothers car if you are interested. |

I had the same problem. I checked the distributor shaft for play and found the bushings were sloppy. |
