Yes replacing the points can advance the timing and therefore
increase the RPM. If the points were closed it would retard the
timing, the opposite (advance) would happen if the points were open
too wide. Thats why you set the points before you set the timing.
The other problem sounds like you have moisture in the bowl of
the carb. Drain it out and catch it in a glass jar. See the water in
the bottom? You may still have some in the tank also and the fuel
pump keeps adding it to the carb bowl. If you pull off the top of the
carb you would see water in the bottom also. Or if you have a glass
bowl filter system you would see it there also.
Sounds good that you have it running at least, take a spin around the
block for me, and enjoy.
