Yup, sounds like weak spark. It idles, but when the engine speeds up a bit, the higher cylinder pressures snuff out the spark.
Sounds like a coil breaking down.
Here's a freebie to confirm this. Close the spark plug gaps down to about .015". This will make it easier on the coil as jumping a smaller gap requires less secondary coil voltage. Also close the points gap a bit to provide more dwell time for better coil core saturation.
If it runs better, replace that old coil, condenser and points. Don't forget to re gap the plugs. The wires are probably crappy also. Mine runs ok on 30 year old wires though. Until it rains.....
