There. A little punctuation prevents mistakes.

 

Why do you think the cam is out??? Was the motor taken apart also??? If no or unknown lets leave it for now. Because the carb was rebuilt it is highly suspect that it was done incorrectly.

 

If you have fuel and spark you can get it running....

 

FUEL

Look at the front of the carb. There is a small round glass with a dot in the center. Fuel should be up level with or close to the dot.

Look down the carb and work the throttle. You should see a strong squirt of fuel.

When starting the choke plate should be closed.

 

SPARK

Stick an old plug in any of the wires and lay on the valve cover or any grounded surface. Crank motor... you should see sparking.

Set motor to TDC #1and take the cap off. Confirm that the #1 wire is directly above where the rotor is pointing.

Confirm that the wires are 1342 in this order.

abjusting the came timing is not the same as abjusting ignition timing.

:lol: Unless he confirms the engine was apart, I'm going to assume the came timing is probably fine for now.
