allis B firing order

tooltimejim · Dec 12, 2009

After I made sure crank gear "-" mark and cam gear mark matched, and the "o" mark on cam gear to governor gear matched, I find im exactly 180 off. I looked at pictures of the tractor plug wires I took before I tore engine down. If I did this right: I brought engine to TDC ON #1 , looked in hole on left side , and "center" was in window, I then installed distributor ,I installed plug wires 1,2 4 3,clockwise, It STARTED RIGHT UP,SOUNDS GOOD. But when I look at the pictures of before I tore engine down, The plug wire #1 I have now is located what used to be plug wire #4 in the pictures I took before tear down of engine/. thanks Jim

no 1 should be the front cylinder . 1243 is firing order. when the distributor went in and meshed up with the gear and no1 piston up it located the rotor button to a post for number one it sounds as if thats the way you wired it or it would have missed. if you want number one some where else on the cap you will need to get it back to tdc on number one then pull the distributor and rotate the rotor button until it aligns with the post you desire and meshes with the gear at tdc on no1

Well. I double checked things, and looks like I confuse myself a bit more then needed, you all understand, your dealing with a rookie here, I have to read then wrench, and repeat. I went back out to shop, found TDC on compression stroke, checked window, and "center" was in the window, I then noted position that rotor was pointing,and it was pointing at #1 piston. So Im leaving it the way it is , it starts first crank, runs smooth, no need to mess with im thinking. why the #1 plug wire is 180 off from the pictures i took before I tore engine down, has to do with the distributor gear and governor gear relationship. Thanks Jeff! and everyone that has helped me understand things... Learning is a good thing!, Jim

Where #1 is on a distributor cap is no big deal. Shoot on some you can set it up to be any of them just by pulling the distributor out and dropping it back in. So ya if it bugs you that you have it on a different nipple you need to pull the distributor and turn it 180 and slide it back in, but the problem other then maybe being factory correct is in your head. I.E. it will run just as good that way as it did before

Thanks Old, Im learning. Seems I have a way of complicating things more then needed. Maybe to much thinking, and not enough doing. Thanks again,jIM

Just to give you an idea of what I'm talking about. I have a 1935 JD-B and if it was factory correct the top nipple on the mag would be the left cylinder and the bottom one the right but I have the mag on it 180 out and it has been that way since around 2003 when I got it back up and running

engine fires 1-2-4-3. if it starts and runs your o.k., turn it 360 degrees on the crank and it will be at TCD, and #1, not #4.
