If the rpm is wandering on the tach, your distributor shaft/bushings may be worn and need rebuilding - changing points will not fix the problem if that is the case. Take the cap off and give the shaft a wiggle side to side. Ideally, there should be no play; if it's loose enough to visibly change the point gap, it's a problem. Assuming you've got good fuel floe to the carb, I agree that the carb accelerator pump needs to be checked if it's bogging when the gas pedal is floored.

Hi Ozstatman,

Thanks, I registered months ago!

Question for everyone: are the 3 transmissions noted interchangeable, or in other words, do the 4-sp non-synchro, 4-sp synchro, and 3-sp have the same bolt pattern to the block, splines on the input shaft, overall length, etc? It seems like one would be able to bolt in one for the other, if necessary (with maybe different mechanism for pedal actuation), despite the difference in internals.
