I had just hooked up my box blade and started it up. Ran about two minutes and died. I have checked everything. I had put about 1/2 gal of fuel in (last of the container) and thought it may be water in the gas. Drained that out and put in fresh. No go. Used starter fluid. No go. How would you check to see if the timing chain may have jumped? I looks as if the number one on the distributer is now in the 2 o'colck position. Seams as it might be 180 out. I don't want to reset the distributor because I found in the pasted it to be a real headache. Any ideas.

Had the same problem yesterday, been fooling w/it for a week.
Finally took a pice of very fine sandpaper and sanded both sides of the points - VOILA!!! It started on the first try.

Try sanding the points, with a flat, very fine sandaper. Make sure they are absolutely clean after sanding - it may take more than one try to do. You can also replace the points, I reccomend Bosch points after what I went through on mine. Replaced the coil, cleaned the plugs, new rotor, cap, and condenser. It turned out to be the points - I never would have guessed that. Points looked brand new.
One way to check if there is adequate fire to the points is to ground the swing arm to the rotor cam shaft with a screwdriver.

It costs less than US$100 to make most of these problems go away....

No points, no condenser ... no problems.

Saw your reply, is the conversion kit or parts you mentioned for 6V or 12V systems? Where do you get one?
Thanks

I'm not sure if your turns over and will NOT fire, but this sounds similar to my 35 when I took her out for her first spring ride....15 minutes into it she died..... .cranked, but no fire.
I looked at points and the "rub block" was melted/ground down and points were not opening back up.
Just a thought.

If you think you jumped timing, you don"t have a choice but to retime it unless you want a piece of lawn art! As george said, there are no timing chains to slip. If you need a walk through on retiming it let me know or look in the archives.
Are you sure that the timing changed? ARe you sure that you don"t have an ignition problem?(FAT, BLUISH-WHITE SPARK???)
The real question is how could the timing change? Was the distributor loose or is the cam thrust plate so worn that the the timing gear moved out enough to jump out of gear? Is the timing gear loose?
It appears to me that, if in fact your timing did change, you need to do some investigative work before you put this tractor back into use.

Gene, followup on what the other guys already said. Your TO has timing gears, no chain. I really doubt that is your problem. Sounds like an ignition problem to me. Check your #1 spark as John describes. Also check that your spark is a fat blue spark, not a weak orange/yellow spark. Your TO will not run with a weak spark.
Your distributor is actually very easy to remove/install & line-up on #1, if needed, following the same procedure John has already pointed out.

When you checked the position of the Rotor was the engine on the compression stroke on number one cylinder, you may have been 180 deg out. Remove the number one plug and turn the engine slowly with your finger over the plug hole and when you feel it pressing your finger then it is on compression, at that point check the position of the Rotor, if the distributor is in the right position the rotor should be pointing to 10 o' clock. check the centre contact on the inside of the distributor cap that it is free and touching the Rotor. Remove the centre HT lead from the distributor cap and turn the ignition on and spin the engine over on the starter, if you hold the end of the HT lead close to the block you should see the spark jump, a nice big blue spark, not a weak yellow one. Check the points gap that it is correct and that there is no wear in the bearing on the Distributor shaft....John

Gene, when you last used it did you turn the gas shut off valve off and forget to turn it back on? Don't go looking for a timing chain as you won't have one. You have timing gears and the likeliness of them having been jumped is ZERO. As I believe Jerry MT would say start by checking to see if you have a big fat bluish spark, if you don't find out why. I don't believe there is much to resetting the distributor. The first thing is to make sure # 1 cylinder is on the compression side and at the top of the stroke. Then put your distributor in with the rotor pointing toward # 1 wire. Need more help come back to the forum. Good Luck Richard

This problem sounds very similar to the one described above. I have a TO-20 about 1948 model. I cannot get it started � it is still the old 6 volt system, and I have rewired it, and double checked all the parts. I�ve replaced the coil and condenser, the cap and rotor look good, and I put new points in it last year.
It appears that there is no spark � could the connection from the stud the points mount on to the coil be shorting out?
