What's common between 1342 and 1234 is the 3&4 so maybe 1&2 are wrong, but you say 1 is TDC on the compression stroke. Are you sure? Love to see a photo, even better, a movie. You would need to have a different crank & cam shaft to all others.

Thanks will try 1 & 2 , see how it goes ... il take a photo but the movie is out of the question!

In australia the firing order is anti-clockwise. So starting with #1 plug wire count off 1243. Or clockwise, 1243.

Ok sorry dude the firing order is 1243 not 1234 but it still strange i tried the 1,2 swapover & got missing and backfire so back to firing order? i got no idea but heres a picture of it anyway Dooffy

thanks for the reply i am a dooffy couse i posted my problem wrong the firing order is 1243 not 1234 how dumb. but it still says in my nissan factory manual the firing order is 1342 go figure
& the firing order you have given is what im running so it must b right is there any thing i can do to give her more pickup where needed thanks dooffy

1342 is 1243 backwards!!!!

The dizzy runs the other opposite way to the crank! You have it set up right, you are just reading it backwards!

Do you have all the tune up specs? It might not be a rocket ship, but there's no reason for it to be be any slower than it needs necessary. If you give it the once over in the tappet department, then set the dwell & the timing. Make sure that both the mechanical & vacuum advance are working as they should & it will run as good as it ever will without additional mechanical work.

hey thanks gunna try the vacume,s today ill post u all to let you know i went thanks dooffy
