Timing
'66 coupe with 327. Crane electronic ignition. Accel coil and wires. Will only start with timing way advanced (25 deg) Will run ok set there but hesitates on acceleration. If I back the timing off to 10 deg it will idle rough and wont restart. Has a Holley 4160 non adjustable carb. Any ideas??

even if you may be a tooth off, the fact that you can get it set at 25 or 10 means the dizzy is in phase...
check the weights and advance mech.....

Disconnect the vacuum hose from the carburetor, plug the carburetor. Disconnect the hose to the vacuum can. Put the timing light on number 1 plug wire (driver side front of engine). Read timing. Should be close to 8*. Rev motor up to about 2500-3000 and watch the timing tape. It will come up and settle at about 34-36*. If so, timing is close. If not, you are off with the distributor. These are just close numbers as they vary. But are ball park.

Personally, I don't think the OP has given enough information for anybody to make an educated guess at what is wrong. Maybe he set fire to it and walked off!

I've sat at the table? Maybe so. Wasn't me with the pointy hat sitting in the corner though.
Without stepping on toes, the side discussion was clarifying that the oft quoted 'being a tooth off or indexing the gear' idea is only applicable in cases where the distributor housing cannot be rotated sufficiently to achieve correct timing without causing mechanical interference.
That does not appear to be the case here.

Like I said, there isn't enough information to operate on here.

You're right that there's not enough information here, but that's compounded by giving incorrect troubleshooting advice.
