I know it's possible to drive the driven dog's pin pin out and rotate it 180 then reinsert the pin, but how you got 90 degrees off is a puzzle..at least to me..
One way out is to pull out that drive gear and reinsert it in the block so that your rotor is pointing to 7. A clockwise rotation of 90 degrees should do it.
Just a pain taking into account the natural rotation as the drive gears mesh with the gears on the cam..

Being off by 90 degrees suggests a mechanical problem in the dizzy to me. I'd want to verify that the roll pin that locates the drive dog to the shaft is in good condition; and then double-check the advance mechanism (which is what locates the rotor end to the main shaft). Also make sure the rotor is properly installed (and the little tab that locates it to the shaft isn't AWOL).
On a friend's TR6, it appeared that some previous DPO had dropped the nut for the points down inside the dizzy and left it there. It had done considerable damage to the advance mechanism, and the engine ran a whole lot better after we sourced a different unit with a working advance.

My dizzy is correct. I just rechecked it.
Don't you also have to rotate the oil pump too, to get it lined up with the cam gear?
Now I am wondering if I did have it at TDC.
Took the valve cover off to check it before the diz came out.
I wonder if I am 180Âş off???

Yes,another complication, the oil pump drive shaft.
Make darn sure it's lined up if you end up having to do that..
If it's not, when you seat the distributor you may shove the OP shaft down into the OP and never interlock with the drive gear..
BUT I believe Randall may be onto something about the problem being within the distributor.. Before you remove the drive gear see if it is in there right. Rotate the crank 90 degrees Counterclockwise then come back 90 Clockwise and see if you have compression in cylinder #1
Finding TDC should be easy enough to check Remove the spark plug and feel for the compression try to blow your finger off the top of the hole as the piston rises with both valves closed.
Watch your damper, it'll mark "0" on both TDC compression and again on TDC exhaust. Don't confuse the 2.
If you have compression and the slot is still at that angle pointing 1 to 7 o'clock, then it's right and the problem is with the dizzy for sure.

Thanks guys,appreciate all the help.
Just got it back from Jeff so all of that is good.
Got it Ken
Had Dave come over and we refit the cam drive. It was 180Âş out. And spun it so that the #1 was close to the 7:00 position. Tighten everything up and it's on to the next thing.

Something Dave wondered about.
The stud for the intake looks like it has interference with the #3 exhaust pipe.
Might have to go with a socket head bolt there.
Thanks Again Dave

Saw that. The pedestal won't fit down right if it is not in the oil drive.poolboy said:
