Farmall A Running on Two Cylinders

Posted by Rob Flatness on July 17, 2010 at 20:23:50 from (97.195.40.81):

I have an A that was converted to 12 volt before I purchased it a year ago. It got to where it wouldn't start back up after it got hot. It has an H4 magneto so I thought it would be cheaper and easier to convert it to an auto style coil. After wrestling with this all day it started first crank, but is grossly under powered. After pulling the plug wires I discovered that it is only firing on the two middle cylinders. The other two do not have enough juice to arc the spark plug gap. They do have a slight amount if you touch them to the block.

Should I jump right in and replace points, condensor, and distributor cap? Could I have messed up somewhere on my wiring. The coil that I got is a 12 volt and I have a 6v to 12v resistor, but I can't tell you anymore than that. I just bought what the farm store parts guy gave me. Would the coil not be right?

Any help would be great. I have already spent most of my weekly allowance, so think enconomy if possible.

Thanks,

Rob

Today's Featured Article - On the Road with Dave Gohl: Tractors and Farming - by Dave Gohl. I never thought I'd live to see the day, when I could call myself a farmer. What allows me to say this? Well, when our family moved to our 20 acre site near New Prague, Minnesota, I had one thought in mind. You guessed it, farm it somehow. A little history is in order. In my younger days, mom, dad and my brother made frequent visits to dad's youngest brother Pete, who took over the home farm from grandpa MIke. It was the typical set-up, milk cows, pigs & chickens. In the winter, we'd play ... [Read Article]
