    Default Tuning Help

    So I drove the M715 about a week ago and it cut off on me while I was driving down the road. It would turn over it just wouldnt fire. I assumed it was the coil so I replaced it. Still no start. I then checked the point and made sure it had spark all the way to the plug and it did. The points looked like they were bent a little, unsure why. So then I tried adjusting the timing and I had to turn the distributor all the way clockwise and I finally got it to start. it still sounds as though the timing is off but its running ok now. What would cause the timing to go way off like that? Was wondering if maybe the timing chain may have skipped. Not sure. Any thoughts?

    The timing chain does not drive the distributor. If the cam timing jumped, engine would have low power. I would put a timing light on it and see what you got.

    If the cam timing did jump how involved is it to fix that?

    Haha same question a lot of Ford Triton engine owners ask. The chain has a tensioner which prevents jumping, it likely needs replacing, the front timing cover has to come off.

    Also I havent been able to get a timing light to work properly on this motor. I tried using a regular plug wire and it intermittantly gets the light to flash. I adjusted the timing with a vaccum tester.

    Use a plug wire with wire core. Need to have good diagnostics before opening the engine.

    Check to make sure the pin on the distributor gear didn't break and allow the gear to move. It can cause all kinds of timing issues if it did.

    Ok 67Beast gets the big gold star. Well almost. It looks like the metal tab snapped off the bottom and its not turning properly. Ill need to order a new shaft for the distributor.

    I know thats totally crazy. Does anyone have a replacement shaft or the bottom half of the distributor to sell? Or know where I can get one? Im going to try to get the metal tab out using a magnet Im not sure if its still down in there or not. It might be floating around down there in the oil. I wish I had a diagram of the entire shaft all the way down to the oil pump. Is there one on here somewhere?
