Firing Order stamped on block should mean?

Might be a stupied question but I am guessing the firing order stamped into the block of my B414 tractor which is 1342 with 1 being at the battry/gas tank and 2 being at the radiator. I was told 1 was at the radiator but the block is marked out as such.

If i go in a circle starting with #1 at TDC at the gastank end of tractor I should then work counter clockwise with number 2 coming from the front of tractor(rad) number 3 comming from the middle closer to (tank) and number 4 comming from the middle closer to the (rad)

Does this sound correct or am I missing something??
 
The cylinders are numbered front to back 1-2-3-4.

"1342" is the firing order. Front cylinder fires, then the third one back fires, then the rear cylinder fires, then the second cylinder fires, and it starts over again at the front cylinder.
 
from the radiator to the gas tank it is 1234. firing order is 1342.
at the cap in the ignition (looking forward) they are usually:
2-1
4-3
Rotor turns CW. Jim
 
Number 1 is the first cylinder by the radiator with 2 and 3 following and 4 is closest to the fuel tank. The stamping on the side of the block is the firing order not the cylinder identification order.
 
If I understand your question correctly, #1 cylinder should be next to the radiator, next is 2 with #4 being the closest to the seat. The firing order is which plug wire in order goes where. Cylinder #1 fires first, then #3, then #4 then #2, then #1 again and so on. The trick is finding out where #1 is on the distributor cap. Sometimes it is stamped on it, and sometimes you need to pull the #1 spark plug and with a long piece of wire to stick in the cylinder slowly turn over the motor until #1 cylinder is on top. Then pulll the cap off of your distributor and see which terminal the rotor is pointed at. This will be a 50% chance yoU are right, if it will not run or runs very badly then change all plug wires with the one on the opposite side of the cap and this should remedy this.
 
The way I understood the original question, he thought the cylinders were numbered, back to front, 1-3-4-2. Meaning the rear cylinder is #1, the second from the rear is #3, and so on...
 
hey all - thanks for the feed back. Just to throw my self off even more I looked at distributor cap and the center cap shows an arrow turning counter clock wise not clockwise and I turned the engine over and it does turn counter clock.

so If i understand correctly the cylinder by rad is #1 and I should find TDC. in the firing order the next cylinder to be fired will be number 4 By gas tank. Which one is next?
 
had to draw a map -

cylinders are numbered 1 - 4 from rad working back.

fire 1 is at rad,
fire 3 is 2nd from the the gas tank
fire 4 is gas tank
fire 2 is second from the rad

Like this?
 
Dude you REALLY need to get a manual and stop working on that tractor until you can get some help that knows something, The firing order stamped on the block has nothing to do with the cylinder layout. Number one cylinder is at the FRONT RADIATOR FARTHEST from the seat. #2 is next back, #3 is next then #4 nearest the back of the tractor,
 
NO NO get a manual, Firing order is 1342. When you finally find number one (1), the next to fire will be number three (3)
 
The rotor does turn CCW, I forgot it was not the same as the letter and 1XX series. (Do not let rude people disturb you. Some are a bit more directly spoken. learning is a great thing and Because I teach, I know ignorance can be cured, stupid cannot even be addressed.)
 
You watch which direction the rotor turns and most of the letter gas tractors turn CW. Hal

2-1
4-3

Go back and read again. He's got the right idea, just a strange/confusing way of expressing it.

This is NOT a letter tractor Hal. It's a B414.

Those Brits are weird.

Was the tractor running before? If you didn't change the plug wires around yourself, odds are nobody else did. They don't move around themselves.
 
So they would go in this firing order. Hal
PS: You may need to bring No1 piston to TDC on the compression stroke to see where your rotor is pointing.
1-2
3-4 rotor turns CCW
 
YOU go back and read his post of 02/04/2012 @ 4:21 PM my
answer is still correct #3 fires after #1 .He posted #1 then #4
and wanted to know next.
 
Wow, had several days away from the site; at work driving. This has to be one of the most confusing and entertaining threads I have ever read! The advice to get a manual should be taken. Also, some a basic motor training manual with the usual info, four stroke motor, the firing process, inlet and exhaust valves, carburetor (or carburetter if made in England) and ignition system. It is not a great deal of use knowing the firing order if the principles of engine operation are unknown. As has been said, we all have to start somewhere. I am learning a great deal about air suspension systems on buses at present, and have found that, while I know a fair amount concerning old motors and machines, I am a complete novice on air suspension. The mechanic at work helps me and I am learning. Never be discouraged.
