please help...distributor issue

Postby itpdk9 » Thu Feb 11, 2016 8:46 pm

Hello all,

So I got my cub all put back together and it looks pretty but I can't get it running. When I took my wires off of my distributor cap I had a weak moment and didn't write down the firing order on the cap. So now after multiple searches and reading what I could find, I know the order on that cap I put the wires in that order and I got nothing. Then I was looking at peoples setups and noticed that mine looks different which would change where the wires go in the cap.

If you are still following with me, on my distributor, which is a rear facing cap, the grounding screw is on the under neath of the distributor and the notch on the cap is all the way at the top. On the pictures I have seen everyone's notch is at the bottom with the screw to the outside of the tractor, not up against the block like mine is. SO my question is this what would my wire order be on the cap since I think mine is 180 degrees off...?

Any help is much appreciated, I would really like to see and hear this thing run again!

firing order is 1342, if the distributor is and installed and timed correctly the stud for the ignition wire should be sticking straight out from the engine, #1 cylinder wire on the cap is the terminal right over top of the stud, the firing order is clockwise from #1, the clips on the cap should be about 12 & 6 o'clock, some caps have a #1 marked on them
good luck

Ok, my clips are at 3 and 9 and my stud is near the bottom beside the block. Do you think if I start where one should be and go clockwise it will work? I will have to try in the am. I really don't want to have to mess with retiming and such. Thanks of your response tst

If you can find TDC on #1 it is easy to make it right once and for all.

You have a 51 Cub. Is it a distributor or a magneto? Two completely different animals.

Hi,
Here is a page from the Cub owner's manual showing the ignition cable wiring, and how the distributor should be turned when it is timed correctly. The lower left pic is easier to see maybe. :)

Easy with the hood off, but take out the plugs and hold your finger over the #1 spark plug hole. Crank it and when you feel compression, that is #1. Set it on TDC using the notch on the crank pulley. I like to put a dab of white paint in the groove with a modeling brush to make the mark easy to see with a timing light. This is easy to do with a hand crank and a helper if you have one.

Next remove the distributor. position it like Tim described and rotate the gear until the rotor is pointing towards #1. Slip the distributor back in. You may need to play with a tooth clockwise or counterclockwise to get the clips at 6 and 12. Snug the clips that hold the distributor, many do not use the back one as it is hard to reach, and you are at TDC on #1. Easier to set the points while it is out. With the clamps snug but not socked, you can rotate the distributor when it is running to set the timing.

just use the starter. Even if you overshoot, just put it in gear and use the rear wheel to rock it back to TDC. Just make sure it goes back to neutral before you crank it again! May take some trial and error, but you will fell the pressure of the compression stroke.

I think if you have all the plugs out, you can probably turn the engine with the fan to get to the compression stroke on #1. You should be able to do this without removing the fuel tank/hood, too. Good luck!

to rotate, you can reach in to the fan belt and push tension on belt, with the other hand, rotate fan blade and motor should turn.
align with the second notch on the crank pulley
