Thanks for the many replies below, I keep my tablet handy in the shop so was able to access all of those. So I started out with the points today, loosened the screw and regapped. I then checked the spark from the coil and then each plug. The wires are correct, I never undo more than one at a time unless I mark them with tape. Getting a little frustrated because I really don't have the experience to recognize a good spark. It jumps a quarter inch, but blue??? Are we talking blue/white? Cause I got a yellowish with some blue in it. Pretty lively though. Took a walk. Decided to pull the drain on the carb and get some gas out of it. This is where I had my OOPS moment. The thing I pulled was not a drain, it is some kind of needle. Most of the older Farmall tractors seem to have a drain on the end opposite the air intake but this fool thing has a needle for what I assume is one of the jets...but I dunno. Anyhow, it was out and the flow was pretty good but the gas was murky and had water in it. I took out about a quart of gas. I put that needle back in but had no idea how far so just until it snugged down. Told my wife I was screwed because it would never start with the carb out of adjustment. Turned the key and it fired to life. Ran pretty good too. I think my chin hit the floor I was so surprised. Sooooo....can someone tell me what this needle is that I unscrewed at the end of the carb opposite the air intake right at the bottom?
