When you replace a point set and reset the gap, this automatically changes the timing. So you may have to reset the timing. Then;
If it still won't take throttle, the first test is cam timing. Well, actually a close second would be a plugged muffler, but checking cam timing is easier, and faster. If the cam timing is good, then reset the valve lash while the valve cover is off. After that,check for a plugged muffler.
If the engine runs, the condenser is doing it's job. When the condenser quits, so does the running. If the capacitance is wrong it usually just burns the points up prematurely. In the old days, I ran the same condenser for many years.
