How was your 34 degrees of dwell determined? KRW or sun machine?

Also Check the spring tension on the terminal stud on the distributor (should be stiff). be sure the tip of it and the brass contact on the breaker plate are clean. When it dies are the plugs wet? If not, does any starting fluid down the carb make it start? Are you running Dennis Carpenter brand points? if so replace them. Is your fuel cap or sending unit depending on your tank set up venting properly? (This one kicked my butt one time)
