Assuming the issue isn't old/ethanol gas, I'd first check the timing/points gap, then the advance mechanism in the distributor (I take it that 29's had an automatic centrifugal weight advance) which might not be advancing as it should be, then carburetor issues such as running too lean or improper fuel float level/excessive pressure in the line.
