[AT] Cub update Part 2

[Greg Hass]

Although I basically have battery ignition on my cub, it is not what I 
had planned on all these years. First of all, I never planned on doing 
anything unless I had to; second was if I had to I was going to get a 
complete used battery ignition unit. What I now have is a converted mag. 
The original mag is still on the tractor and still uses the impulse 
coupling for timing purposes. All I have done is replace the mag coil 
with a battery coil. In fact, the coil I bought has a mounting bracket 
with the same screw spacing as the mag coil cover, I only had to buy 
slightly longer screws for mounting on top the mag and was even able to 
use the same coil to distributor wire. Each time I went to the dealer I 
got a little more information,such as the points and condenser are the 
same for either mag or battery. Every thing I read and a couple of 
mechanics I talked to all said to leave the points set at .013 for the 
mag as opposed to .020 for battery. All had the same reasoning, 
including me, the the reason is that the point lobes on the mag are 
quite different from true battery ignition making it necessary to keep 
the mag setting. There were a couple of reasons for going the route I 
did, one being the time factor; once I determined The mag was the 
problem I had it running in a couple of hours. Second I didn't need the 
hassle of trying to find a used one plus wondering if it was good. 
Third, the average price that I have seen on places like E-bay has been 
around $200. Fourth, the cub I have has only top dead center marked on 
the front pulley. with the mag set it there and the impulse takes care 
of the rest.
