Hi,

My dad and I have been trying to get an old 1954 Allis CA running that has been sitting in our barn for ~15 years. Originally we were dealing with a seized motor but after taking the head off and a lot of persuasion that problem was fixed.
After reassembly the motor turns over great but will not start even with starter fluid. After taking out the plugs and trying to start the tractor it seems to be that there is no spark. Before going and checking all the wires and distributor and stuff, I zeroed in on the little box that has the battery ampere gauge, keyhole, and a small switch that I believe you are meant to pull out to turn on the lights. I have never actually ran this tractor myself so i'm not sure, but my dad seems to think that there will be no spark unless this switch is pulled out. However it seems to be seized in place really hard and despite some fluid and both of us trying to get on it with a pair of vice grips nothing seems to be working. Before I go any further I just wanted to ask the experts if this switch does need to be pulled out to start and if so if anyone has any ideas for getting it unstuck before I go and buy a new one.

A CA with a magneto ignition had a push-pull (grounding) switch and one with a battery ignition ( coil & distributor) had a key switch from the factory.
My opinion it would be best to check the wiring and see where things go.
Previous owners sometimes have a habit of changing things to cheaper or more convenient alternatives.
If equiped with lights, the light switch operated seperate from the ignition switches.

Hi, it's been a while but I have been steady tinkering with the tractor. I looked at all the connections I could with my multimeter/screwdriver test light and didn't really get very far. I thought my points were corroded but while tinkering today I tested one of the terminals on the coil and heard a loud pop + some smoke which seemed to be coming from the exhaust area. After that I went to try to start the tractor and I seemed to have some combustion happening (and therefore spark?) but it still sputters and dies without starting, even with ether. I have a hunch this could mean my timing is messed up? My plugs are wet, so I'm pretty sure I've got fuel, spark, and air. I am apprehensive about trying to retime the engine/distributor as it seems a bit difficult and want to eliminate everything before I do that.

Improper spark plug wiring? Dave is right. Light circuit is separate from the start and running circut.

I have new spark plug wires, and installed them according to the service manual, so I'm pretty sure they are all good. I was also possibly wondering if maybe my plugs themselves could be bad?
