As I believe I told you before, it does not matter where the rotor is pointing, so long as when the motor is at TDC on #1 that the rotor is pointing at the #1 plug wire.

I KNOW IT SHOULD BE BUT IT IS NOT,WHEN #1 IS AT TDC THE ROTOR IS POINTING AT THE #6 CYLINDER RIGHT NOW AS I TYPE THIS.I THINK THE GUY THAT BUILT THE MOTOR PUT THE DIST.IN AND MADE WHAT EVER CYLINDER THE ROTOR WAS POINTING AT #1 IS THIS POSSIBLE?

Again, as I said before, twice now. Are you reading what I'm typing?

It DOES NOT matter where the rotor points, so long as when the motor is on #1 TDC that the rotor is pointing at #1 in the cap.

If the motor is on #1 TDC and the rotor is pointing at the #6 plug wire in the cap, then yes, it's wrong.

Jeff when he says #1 on the cap that is wherever the #1 plug wire is on the cap. Doesn't matter which place on the cap you put the #1 wire as long as the rotor is pointing at it at TDC.

You might have someone give you a call and talk you through it on the phone, could be easier than reading it.

NOW,WHEN I GET THE MOTOR TO TDC ON #1 I SHOULD ROTATE THE BALANCER TO THE TIMING I WANT WHICH AT FIRST WILL BE 34*BTDC.AND THEN INSTALL THE DIST.SINCE IT IS LOCKED OUT.

NOW THAT I HAVE CALMED DOWN I CAN SAY THE THE ROTOR IS POINTING AT THE #1 PLUG WIRE ON THE CAP,NOW THEN WHEN I ADD TIMING THE MOTOR RUNS ROUGH WHEN REVING IT WITH NO LOAD ON IT,36*TIMING.COULD THIS BE IGNITION RELATED OR SOMETHING ELSE?SBC MSD 6AL 2,85551 DIST.BLASTER SS COIL.

No, you're not under carbed.

Can you make a video and upload it? What you call rough and what I call rough may be two different things.

Some carbs run rough at part throttle. I know you said it was a gas motor, so it's not the typical alky roughness at part throttle. You didn't say, however, whether the motor has power valves in it, or if the power valves are plugged off. If there are no power valves, it will run rough at part throttle.

If, however, you can back off the motor 2 degrees, and the 'roughness' goes away, then you may want to try closing up plug gaps to like .018 (just to try it), then up the timing.

If the roughness still occurs, it's time to start changing out electronic parts until you find the culprit.

It could be:

1. cap, rotor, or both.
2. Old plug wires? Have you checked the resistance in each plug wire with an ohm meter?
3. Coil going bad
4. Points in the dist? If points, have you checked the point gap?
5. 6AL box going bad.
6. Excessive plug gap
7. Bad ground... The coil should be grounded to the battery and heads (both heads) via dedicated leads.

Those are all things off the top of my head that can cause 'roughness' due to ignition issues. This is assuming that there's nothing wrong with the carb.

A simpler thing to try would be changing the carb out...

IT IDLES FINE IT MISSES FROM ABOUT 3000 RPM ON UP NO I HAVE NO WAY OF UPLOADING A VIDEO.NEW CAP&ROTOR,NEWPLUGS,NEW PLUG WIRES,NEW MSD 6AL2,BLASTER SS COIL IS A YEAR OLD,GAP IS AT 35.COIL SHOULD BE GROUNDED THE BLASTER SS NEEDS TO BE GROUNED?I JUST HAVE THE BLACK AND ORANGE WIRE FROM THE IGN.BOX HOOKED TO IT.I PUT MY OLD 750 ON IT AND IT STILL HAD THE MISS.
ALSO I WANT TO THANK EVERYONE FOR THEIR TIME AND HELP.MY CAPS LOCK BUTTON IS BROKE ON MY KEYBOARD THAT IS WHY IM TYPING IN CAP'S.

just a thought, is the coil mounted close to anything where spark jump, could be an issue?
