Bwahaha! I can always count on you Steve-o!
Now, not wanting to throw the towel in just yet, I slapped that harness back in to see what’s what here. Miraculously, the electrical gremlins I had have disappeared! Which leads me to believe that still something is goofy in it, but between Darrel’s key buzzer thingy and taking the harness back out and strangling it like Homer does to Bart, resulted in the weird gremlins going away. However.... It still won’t start and now I am getting 12V during cranking, around 7 at the run position. So that’s normal, but it still doesn’t start. That leads me into the next trouble shooting phase and that’s spark. Gas simply isn’t the issue. Pulling the plugs, they’re all soaked and black. So they’re all fouled up. So that’s step one....why no spark? I put the engine back at 10 BTDC and pulled the cap off and here’s what I found doing that; the rotor was nowhere near pointing to #1, it was more toward #8. But I had set this exactly at #1 several times since I thought the timing was the initial problem. So tomorrow I’ll try to start again and see what happens. What I’m seeing is I position it at 10 BTDC, wire it up, it fires right up. Then after a few minutes, it coughs sputters, laughs at me and then dies. If I go through this again and it repeats itself, and I find that the rotor is no longer pointing to that #1 cap position after it get the engine back to 10BTDC, what could it be? It’ll run and then the timing gets goofey after a few minutes. Keep in mind this engine was built by a guy that has built many, never had any issues, and it’s all good parts in there. I think I’m getting close.... Cheers Dave Last edited by A12pilot; 03-24-2020 at 01:46 AM. |

Mismatched distributor driven gear to cam drive gear?
Or a missing roll pin/woodruff key in the camshaft and the timing chain sprocket is rotating on the cam even though the bolt is tight? |

What I’m leaning on, Steve, may be the pressed on gear/shaft connection on the oil pump intermediate shaft. I’m going to fire it up this morning with new plugs, timing reset, and see if it eventually does the stumble and fumble thing again. If it does, I’ll reposition the engine to 10 BTDC and check the position of the rotor to the #1 cap position. If it’s off, I’ll pull the shaft and see if the gear is slipping resulting in the timing wandering. Stay tuned.....
Cheers Dave |

I have seen the woodruff keys sheer off on a cam/crank. Could have been a soft one and the cam sprocket is no longer fixed in time to the camshaft. The typical 50 cent part sabotaging a big dollar project.

Keep us posted, I wish I could contribute, but you guys are way above my pay grade.

Just to throw in, pull your valve covers, keep eye on your valve timing: IE closed when supposed to?
Coughing fuel out the carb? I'd roll it by hand first, eyeball whats going on mechanically, check reference marks. Dont want valves starting to slap pistons. |

Woohoo! Success!.....well, success in the fact that I knew anything I could come up with wouldn't be the right answer, so....woo....hoo...
It's all back together and here it'll sit. It's a real shame... such a pretty car with such an evil streak in her. Like a future ex-wife! I'm out of ideas, patience, and interest. So time to just let it sit and move on to the other projects. Thanks for all the suggestions and well wishes to get this poor girl running, but it ain't happening anytime soon. Cheers Dave |

Yea, was beginning to obsess alittle on this one, no closure.
Chased(and caught) a couple of my own gremlins today. |
