I want to make sure I understand the firing order/plug wire arrangement. #1 plug(closest to radiator) goes in #1 socket of front mount distributor cap,#2 goes in #2, #4 plug wire(closest to steering wheel) goes in#3 on the cap and the 3rd plug from the front goes in#4 socket of the cap? Is this correct?

Bruce, Thanks for the response, I've been reading your posts and stuff for years! So the cap doesnt control fire to the plugs? Does each plug wire ,1 through 4 go on the corresponding numbered socket on the distributor cap? or does #4 plug wire go to #3 socket? to get the right firing order?
Yes, #1 is closest to the radiator, then #2, #3, and #4 closetest to steering wheel.
Looking at the distributor cap from the front:
wire from #1 spark plug to upper left
wire from #2 spark plug to lowerleft
wire from #4 spark plug to lower right
wire from #3 spark plug to upper right
ell.....I think I have #3 and #4 switched :roll:(quoted from post at 10:15:46 09/20/17)

Would that cause the backfiring at high rpm? Would a little choke stop the backfiring if the plug wires are swapped wrong?imply swap 3 & 4 & observe the result. :idea:(quoted from post at 13:19:42 09/20/17)ell.....I think I have #3 and #4 switched :roll:(quoted from post at 10:15:46 09/20/17)

If the rotor is turning inside the cap,it comes to and energizes cylinder 3 before cylinder 4 so how can the firing order be 1243 if the plug wire run 1234?(quoted from post at 11:59:34 09/20/17) I don't understand what it is that you don't understand, but maybe this will shed some light?
OT the case:"it comes to and energizes cylinder 3 before cylinder 4 "(quoted from post at 15:05:02 09/20/17)If the rotor is turning inside the cap,it comes to and energizes cylinder 3 before cylinder 4 so how can the firing order be 1243 if the plug wire run 1234?(quoted from post at 11:59:34 09/20/17) I don't understand what it is that you don't understand, but maybe this will shed some light?
Look at the picture....rotor comes to #1, then #2, then #4, and finally #3.
yep, number 4 goes to the third position on the cap to get the firing order right. I use colored electrical tape and make each wire a different color 1-4. Just put a band around it at the top and near the distributor. Put number 4 on distributor position three, and number three on distributor position 4.

Get out your Operator's Manual and/or your I&T F-04 Manual -they both have the diagrams showing exactly how including the original color-coded wires, which you probably no longer have anyway. Since you don't specify what model nor year, the firing order is the same on all whether front mount distributor or the later 8N angle mount style. Here is a picture of a front mount distributor complete with original color-coded wiring...
