1952 Farmall Cub Engine question

Hello;
I am new to this website and forum and the whole tractor experience so thanks in advance to anyone who helps with my question(s). I have just acquired a very complete very original 1952 Farmall Cub. It had been sitting for 2-3 years in a nice dry garage. I changeed the oil, put fuel in it, fresh battery and anxiously (like a kid at Christmas) tried to start it. It cranked nicely but wouldn"t start.
Going to the basics I checked the fuel/air/spark trio and discovered no spark so I took the distributor cap off and off fell all of the very dry spark plug wires from the cap. Now, after I tune it up I have to figure out which spark plug wire goes where on the cap. I have found the firing order (which I assume #1 cylinder is at the front) but can anyone tell me where each spark plug wire goes on the cap. I know this is stupid but the whole process of finding "Top Dead Center" is past my mechanical and intellectual ability. Thanks again, Lou Chicago
 
I should add that I just discovered that I had the battery installed wrong I cranked it for about 5 minutes total and left it overnight(instead of postive ground I had it installed negative ground) - did I do any damage this way? Maybe I should just take it in to get it tunning professionally. Thanks again - Lou
 
Reconnect the battery with positive ground and install your plug wires on the cap in this firing order. Then see if if will start and if the amp meter shows a charge. Hal
PS: That's starting with No1 plug wire near the radiator, then No3, No4, then No2.

You didn't hurt a thing by connecting the battery "backwards" because there is no backwards. The electrical system on this tractor is very primitive and only cares if electricity is flowing through it. Original is positive ground, though.
 
My '49 Cub distributor cap has a #1 at the number one wire position. From there the wires are attached clockwise per the numbers on the left side of the engine. Good luck with your Cub. I like that little tractor a lot.
 
Do put it back to Positive ground (no damage done) it may need the Bat lead on the regulator jumped to the arm lead on the regulator (with it not running) to polarize the generator, if it fails to charge when started. JimN
