I am currently getting the Cockshutt 35 ready to try firing it up. It was stripped of all wiring so I am piecing it back together. Engine is loose so it should run if I get this sorted out.

Question today is which position on the distributor cap is for cylinder #1?

I know the distributor runs counter clockwise so if I know #1 position I can get the ignition wires correct. Distributor is secure so I don"t want to be moving it for this. I have cap terminals at 11 oclock 2 oclock 5 oclock and 8 oclock standing looking at it from the left side of the tractor. Can someone tell me which is #1 without the turning over and pulling valve cover to check for TDC on #1 cylinder with both valves closed?

Thanks Peter

If your 35 is original it will have a Auto-lite IAD4043 distributor and will be set at 0.020 gap. The firing order is 1-2-4-3 in a clockwise rotation. #1 should be at about 8 oclock. Terminal on dist will be at about 6 oclock.

8 oclock is right for #1 and it turns clockwise regardless of what the manual says ,

Thanks for the help. Should get it fired up later this week when the coil and wires arrive.

Any thing else I should be careful on? , it hasnt run in 10 years or so

Sometimes it's hard to "bump" the engine over on the starter button to try and find top dead centre. One alternative is to put your PTO in gear and wind it over with a stilson wrench. You WILL have to find TDC in order to get the plug wires right. It only takes a minute , but will save alot of greif.

The firing order is 1243 , I guess tried and true to figure this one out then.

Some of the AC tractors have that firing order too. This is how your plug wires are probably
installed. Hal
1-3
2-4

Since the rotor turns CCW I would guess the 11 o'clock terminal to be for the No1 plug wire and
install the rest of the wires in their firing order. A lot of these 4 cylinder engines use the
1-3-4-2 firing order, but I know some of the Allis tractors don't.
I would try this firing order to see if the tractor will start unless you know the correct order.
1-2
3-4 Look closely at the cap for a 1 on those terminals. Since the distributor hasn't been removed you don't have anything to lose.

You can always bring No1 piston near the radiator to TDC as Bob described to find No1. Hal

There's NO way to guess FOR SURE if the distributor is still installed as it was at the factory.

So, you need to find #1 TDC. Be SURE the ignition switch is "OFF". Take out #1 spark plug, put a finger OVER the hole, and slowly crank the engine in the normal direction of rotation (CW, as viewed from the front). As the piston begins to come up on the compression stroke, you'll feel air being pushed out by your finger. At the point where the air being forced out stops, and just before you feel suction from as the piston starts to go down, you have located TDC. If you aren't sure if you went too far, turn the engine 1-1/2 turns to get the piston once again coming up on the compression strokee, and try again.

Note where the rotor is pointing, and connect #1 spark plug to that terminal, then arrange the wires around the cap, in firing order, in the direction the rotor turns.

That will get you CLOSE on the timing, and it should start. Hopefully, there's timing marks, and you can then check the timing with a timing light.
