Question about coil and gear inside

Hi
I was having a problem with my Cletrac OC3 tractor dying when hot (after 5 minutes or so) so I did changed the condensor inside the coil and the sparkplugs. I have now no start at all.. I did reconnect the spark plug wire to the right boot on the coil. I also have fire to the sparkplug. However I haven't put much attention to the gear inside the coil, to this gear :
Is it possible that the firing order is wrong now because of this, and this causing the tractor not to start ? If so, how can I "sync" this gear back ? The coil is a Wico XH1113.
Thanks.

We really don't get many tractors in here, but the gear or rotor you have your arrow pointed to should be pointing close to the number 1 terminal in the distributor cap with the number 1 cylinder at top dead center on the compression stroke. That should get the tractor running if everything is ok, so you can set the base ignition timing using a timing light.
Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

Thanks for your reply.
If I understand right, I must place the piston #1 at his TDC and then place the rotor inside the coil poiting exactly to the #1 boot ?
I did found this to help me find the TDC of piston #1.
link deleted ......... not allowed
But how to know which piston is #1 ? It's a Cletrac OC-3 tractor. Do I need the engine model or it'll always be on the same position ?

Yes, it does have to be at TDC but specifically on TDC of the compression stroke. You need to hold your finger over the #1 spark plug hole and turn the engine by hand. As it comes up on TDC compression, you will feel pressure building on your finger. You can stick a coathanger or something like that in the cylinder to see when it's exactly at the top.

Thank you. If I understand right, the #1 piston is the one closest to the front of the engine ? The one closest to the belts ?

It should be but as DS told you, we have no info specific to that engine.
