I'm about to pick back up a project I had to stop a few years back. I recently dropped in a rebuilt 200. We got it started and all was going well till we turned it off and turned it on again. The car wouldnt start. We had to turn the distributor around and it would fired up again. Tried a points, pertronix and duraspark 2 distributor. Similar issues Where should I start looking? I suspect the timing chain (dual timing chain if memory serves me). Any other places I should check? Hopefully I get her home this month Thanks again
1. Think you should find/check TDC. Reinstall distributor and check plug wire. 2. Could also be being a rebuilt motor your valve adjustment is out of whack. 3. You stated engine did start. How did it run? Did it backfire or anything unusual causing it to quit. Starting a new motor or after cam swap is alway nerve wrecking for me. CHECK and Recheck wires. Ohhh and check for fuel. Empty tank got me once!
It would start fine. Never drove it. Idle was smooth. Once it was shut off it was almost 180 degrees off and had a nice backfire. I will verify TDC again, but we did that with each different distributor. We checked fuel... Only cause it was on the floor from a cracked line we addressed quickly
I,ve never experienced a skipped timing chain before. Heard its caused from slack from chain being worn/stretched Your motor is rebuilt. Shouldn't chain be tight?
Yeah thats why we never took the chain off. Its a dual roller chain. I didn't do the rebuild, maybe I should verify its the right chain? Any way to check it without pulling it?
Its been so long, I honestly dont remember. Would I fire up if it wasn't on the compression stroke? It started multiple times, it just had to be re timed each time
No it doesn't, skip on timing chain skews valve timing, generally rendering engine a big lump. If timing chain slips more than a couple teeth, valve timing is off enough that engine won't run at all, reguardless of dist setting. It isn't likely ign timing was 180* out unless roll pin in dist gear is twisted off or the rotor is slipping.
I was reading about the roll pin. At the time, I had no idea that was even a thing. I found these last night.
Just a photo with the timing chain. I it doesnt appear to be loose. I know its just a photo, but it's been a while
Okay....let us help you. And recheck your fire order, Recheck plug wires. Load fuel bowl with fuel and go for it.
Chasing the timing chain is going to be as fruitful as.... If chain or timing gear slips, BOTH valve & ignition timing are skewed. Worse case is maybe the gear on cam has chipped or missing tooth. Possibly there is a mismatch in size of dist gear with cam or again, roll pin sheared. Verify rotor isn't slipping. As suggested verify TDC by compression. I'll bet that never changes.
