Got Spark, Got Fuel.  Hmmm

When cranking it is there any backfire thru the carb?  As others have 
said it could be 180 out.  I'm sure you've probably checked and re-checked.

Another thing to consider if you are sure rotor wasnt 180 out.  Given 
you have spark and fuel, it could be one of the oddball reasons for 
something like this.  For instance, I've seen it happen before where the 
harmonic balancer dried out enough that the outer metal ring slips on 
the rubber and the timing mark ends up being off.  Not sure whether it 
was prevalant on Poly's, but last week, I saw it on a buddies /6 car.  
He could acutally reach down and twist the harmonic balancer (outer 
ring) without turning the engine over.  He said it was the second one 
that he had go bad.  I hadnt seen a bad one for years, but, they can 
eventually slip.

After re-installing the timing chain, if the mark was off on the 
balancer, no mater what you do you dont get it timed.

To Check, you need to use a TDC stop on the number 1 spark plug hole.  
Verify TDC for the piston is also at the 0 mark on the balancer.  (Just 
a suggestion if you havent gotten it running yet)

Sprayed ether in the carb, hit the key and, guess what: no start, no run – EXACTLY the same as before I put the new timing set on. Ack! I pulled the coil wire out of the distributor and spun the motor and have spark. So it appears I have fuel, spark and timing and the same dead boat anchor vehicle. I did look at the timing mark on the crank's harmonic balance and the rotor is pointed to #1 spark plug wire when the mark is 0. Weird.
