Plugs good? Wires good? Dizzy installed properly?
Think gas, fix spark. Vice-versa.

Probably the carb. Sediment stirred up removing or mounting it.
Firing order is 1342.
Set timing to 12 degrees BTDC
Check valve lash just in case.
Set engine to TDC turning the crank up to the zero timing mark in a clockwise direction only. If you over shoot back well up and re-do as many times as necessary. Must be clockwise and stop to remove all traces of chain slack and get a good reading. Now take the valve cover off and look through the top hole in the cam sprocket. You should see the V notch in the back of the sprocket just below and slightly to the left of the small horizontal line etched into the cam thrust plate above it. Like this...
If you have this..... the cam is properly timed
1/ Are you sure you have exactly TDC as described????? Has to have timing mark set to zero on the pulley notch. Cars with big overlap cams have terribly low intake vacuum so this would suggest your cam is off.
2/ Make sure secondary is fully closed at idle.
3/ Check carb gasket and/or adapter are not leaking or cracked from over tightening.
4/ make sure intake gasket is sealing or manifold properly tightened.
