I'm helping my father-n-law with a SuperA that was bought new by his dad in the 50's and has not been modified. It will not start now. Background: It ran fine last year and he has been using a 12v battery for a couple of years now without converting. We use it every spring for planting large family garden. He put a charger on the battery a couple of weeks ago and forgot about it and ruined the battery. Problem: Bought a NAPA 6v as a replacement and it would not start. I replaced the plugs, wires, coil, condensor, points, distributor cap. Then drained the carb for a good 20 secs (bowl was replaced 2 years ago and is clear) as well as took the oil bath off to have straight air. The firing order is correct and I set the gaps. I tested the spark using a Lisle in-line tester and have fire all the way to the plugs. I can't figure this one out; fire, fuel and air should at least let the motor hit. It just turns over without any indication of hitting, no misfires, backfires, nothing. We are going to try and plant ours and a neighbor's garden next week. Any help would be greatly appreciated.
Sounds like you have a good one there! First thing I would do is give it a small shot of starting fluid, if it runs off that, pull the main jet and clean with a small copper wire. It does not take much to clog one up. Hope this helps.

Since it apparently set since last spring you may have a stuck valve or two. Put your hand over the intake and see if you have vacuum on every stroke ( 2 times per revolution)

Thanks for the ideas. I'll check for the stuck valves. And since the carb has not been touched since it was installed in 1952, we are planning on taking it off to clean/rebuild it this weekend.
