Make sure your spark plugs are gapped properly.

Remove the valve cover and confirm the mechanical timing is right and cam gears line up at TDC

Grab a timing gun and check if the ignition timing is correct

All these are very easy to do and a timing gun cost less than $20 at Harbor freight.

^^^^^^ All very good advice. Also, while you're in there, you should probably check your valve lash too.
