Cub 154, Any new carb's, Electronic ignition, coil?

I have just purchased a CUB 154, 73 maybe 74, and need to rebuild/replace the carb, distributor and coil. Is there a better carb to use than the stock? Also, should I switch to the electronic ignition with distributor and coil? Any help appreciated. Thank you.

Save yourself some money. Try to rebuild the original carburetor - unless there are parts missing or broken. Electronic ignition will not make the Cub run better or more powerful so give the old distributor a makeover with many of the items you'll need to get an electronic ignition working as well.

Thank you very much for the info. I will stay away from the electronic and try all the other stuff first. Lots of good posts on the NewGuy No Power.
