TDC set, but still won't start.

Ok wife and I set the timing last night and got the no:1 on TDC. The pointer was just between the double notches on the pulley. I was able to see the piston real easy, and it had a lot of junk on the top of it. But anyway, The rotor was pointing at like 6 o'clock instead of 2 o'clock, so I pulled it off and turned the shaft on the dist. so that it was sitting at 2 o'clock. I then wired it up, checked everything, put the battery in, and hit the starter. Nothing happened. So I am back to where I was. The only things I have not really checked out is the voltage regulator or the 12 volt generator. Could these be a problem? Frustrated yet again.

Ya I can share with you that it is a 1944 model H and a non-X1 model, so it originally ran off of distilate. However it has been converted to using only the larger gas tank, and a gas only carb, I believe. I don't think that it has been modified, but who knows! Yes it ran when I bought it, but during the ride home from New York to Virginia something changed and I could not get it started. Yes I have many shop manuals for the tractor. I have never hand crank started a tractor before and I am very nervous about trying this because the front end loader is really in the way to start this thing. But how hard must you crank on it to get compression on the no:1, because the wife was turning this slowly so that I could see the piston come up to TDC and I never really felt much change in the pressure over the hole. However I would feel a great surge of pressure when using the starter motor the first time I tried this. I wish I could fly one of you guys out here to work with me on this. Anyway, I will try all of these things this weekend, and if possible I might have to call one of you guys if that is still ok with you. Do you guys reccomend me taking off the valve cover so that I can watch the exhaust valves open and close to set TDC? You guys are very helpful, and I hope I can get this running again.

Tanner, Could you share with us a little history on this tractor? If the tractor is new to you, was it running when you got it? Do you know if the engine has ever been worked on before you got it. It is possible someone had it apart and did't get things reassembled correctly espcially under the front timing cover. Maybe we are all assuming too much and are missing something that has been done to it in the past, even before you got the tractor.

Tanner – First off the condition of the generator and regulator have absolutely NO effect on the ignition performance at startup. So you can forget about them for the time being…

As the others below suggest your ignition timing is all messed up. A couple things to keep in mind here:

1 – Simply setting the pulley at the TDC mark and seeing the #1 piston at the top of it’s stroke can result in your timing being off by exactly 180 deg, since the #1 cylinder can be at either TDC compression or TDC exhaust.

2 – The “clock” position of the distributor rotor at TDC itself is meaningless. All that matters is that the rotor be pointing at the #1 plug wire nipple when the #1 cylinder is at TDC compression. (However the “correct” position is at about 2 o’clock)

Here’s how I’d reset the timing:

First set the crank to #1 TDC compression. Can either remove the rocker box, then while watching the #1 intake and exhaust valves, turn the crank until you get the timing mark at TDC with both valves closed. Or you can stick your thumb over the #1 spark plug hole then have an assistant slowly turn the crankshaft. When you begin to feel compression with your thumb continue to rotate the crank until the TDC timing mark aligns with the pointer – about 1/3 of a revolution more.

Next set the distributor: Put a mark on the side of the dist housing in line with the #1 plug wire nipple on the cap. Now remove the cap, then rotate the distributor housing until the rotor points to the mark you just made on the side of the housing. Then rotate the distributor slightly in the direction opposite normal rotor rotation (counterclockwise) until you see the points just start to open and tighten the distributor down.

Finally install the cap, plugs, plug wires, etc and give it a try. If you did it right it should start right up. You’ll probably need to adjust the distributor a bit for best running, but the above will get it going for you.

Good luck!

I would like to Thank You for all the assistance I have received from you and your comments. I have printed out all of your wiring diagrams and they helped me tremendously. It is so nice that people like you; Hugh Mackay and others are so willing to share their knowledge and sometimes wonder if you all realize how much help you are. THANKS AlBie

Oh Tanner Tanner Tanner, Start over. make sure that when # 1 is at TDC that it is on the compression stroke. That is why you were told to put your thmb ofer the hole. see, if it at tdc on exaust stroke it ain't gonna fire. OK now without moving the engine get the distributor set rigt. Yes, the 2 o'clock position should be right, you do this by sliding the distributor back and moving the gear position. I assume you knew that. Now, still without moveing anything look at the points. They should be just starting to open. change this by gently rotating the distibutor. now tighten up the bolts that hold the distributor. If you want call me at 308 340 1548 and I will try to walk you through it.

Take off dist. cap,pull distributor bakc out and point it at 8:00 and reinstall,put cap back on and then try it again!

4 cycle engines hit tdc twice once to fire and once to expell all burnt gasses..Now i did not see your first post so I dont know if you have allready addressed this..

Does moving the Dist so that the rotor is facing the 2 o'clock position mess something up after setting TDC correctly on no:1 cylinder?

YES THAT SURE DOES. You actually put it 180 off again. Either put it back and check it or rotate your wires 180 on the cap and try it.If you had it on TDC compression stroke you were right to move the dist but if you were on exuast stroke then you moved it 180. off . Do you have an IT manual.? Where are you from? have you checked for spark? Maybe a phone call to one of us is what you need to get this straight when you can actually talk to me or some one else and be at the tractor. I would be glad to call you or have you call me I really would like to see you get this . JON
