560 farmall problems???

I got a 560 farmall. has been running fine until about a week ago. I had to dive it back to the house in 1st with the choke on. I have rebuilt the carb and checked the timing. I put new points, plugs, cap and rotor on it. then I put a new coil and resistor on it. whats got me is it turns over great, and I have power to my coil but not to the distributor. am i over looking somthing small? Thanks if anyone can help on this
 
Your description of having to have the choke on would indicate a fuel problem. Do you have a good flow of gas if you disconnect the fuel line at the carburetor? Did you check the fuel filter going into the carb? After that I would take the drain plug out of the bottom of carb and check fuel flow there. What are you checking the voltage on the coil with? The points open and discharge the coil so you would not have constant voltage on the wire going to the points. My vote is a fuel problem. Post back an let us know what you find....we may all learn something!

I started with fuel. I replaced the bulb on the tank, and cleaned the tank out when I did that. I put on a new fuel line and filter as well. Then I rebuilt the carb. I have good fuel flow to the carb. Nothing changed so I started to test spark and found that I had none on any of the plugs. from there I put points, coil, resistor, and a new battery in it. Still no fire. I am stumped at this point. I have been using a volt meter to check voltage with, and all I read is zero. But its hot to the coil. Thanks for any advice you could offer
 
OK...Take dist cap off and take the wire out of the middle that goes to the coil. Leave the wire in the coil. now, look closely at the points and condenser to make sure none of the wires are touching ground where they are not supposed to. If all looks good there (here is where ya got to pay attention to what you are doin) Look to see that the points are closed....if not turn the engine over a little bit till they are closed. Turn the ignition on and gently open the points with a plastic handled screwdriver. You should see a faint little spark at the points gap. If you do then with another insulated screwdriver or appropriate INSULATED device get the end of that wire coming off of the coil near 1/8-1/4 inch from the block or another good ground and while holding it there gently open the points. You should get a nice blue spark every time you open the points (assuming the coil wire is that 1/8-1/4 distance away from the ground) If you have arrived at this point and have a hot spark you likely have a bad distributor cap or fouled plugs. If you didn't get spark perhaps the condenser in the distributor is bad.That is the down and dirty way to troubleshoot. Try it out and post back your findings so we can narrow it down.

Andy's advice is exactly what I would have said for checking spark, cuz I do it that way often. One addition to that advice is to make sure the screwdriver blade isn't touching metal when you push the points open. Another self-taught bit of advice is to make sure your pointer finger hasn't slipped off the plastic screwdriver handle and is touching the metal shank of the screwdriver. Doesn't shock you real bad but it wakes you up.

Your real problem is an engine that's being starved for fuel. Maybe a floating piece of junk made it's way to the main jet. Jim
 
yes I did and thanks for the help. The wire going from the coil to the dist was rotten most the way. I made a new wire and she seems to be running fine. Its always the small things that give you the most trouble. Thanks
