At first I had a problem not getting spark and getting the points gapped right & got that all figured out. After some tries and one battery charge later I got it to where it really runs well for sitting in a field for who knows how long. Big thanks to the stovebolt site because all the answers to my problems I ran into I discovered by searching on here. My next problem I need to solve is my back brakes are froze up. Any suggestions as to how to free them? Thanks again, Jeremy http://s962.photobucket.com/user/jf...0602_204217_zpsu42omktg.mp4.html?filters[user]=138622147&filters[recent]=1&sort=1&o=0

They don't make them new and replacements are very hard to find. I would try moving each wheel both forwards and backwards. Sometimes when the brakes are adjusted up, the rust forming on the inside of the drum causes them to completely bind. | | | | | Joined: Sep 2012 Posts: 20 New Guy | | New Guy Joined: Sep 2012 Posts: 20 | Ok thanks for the info. I was reading on the h.a.m.b that a couple of guys used water inside the drum to break it free. Anyone heard of doing that?
Thank you

They have little nubs that engage the bigger cap on the wheel cylinder piston to get it to turn. If you mushroom them flat then you can't back off the brake shoes.
When you get it all apart use lots of Never Seize on the parts so they won't freez up again. I even use it on the pistons in the wheel cylinders which keeps the aluminum pistons from seizing to the iron cylinder. Be careful not to get any on the shoes.
