firing order

how do you determine a firing order on an 86SN with no Model ID tag on the motor? And THEN any idea on how to determine #1 on the cap since they are not marked? I guess i could do the TDC thing, but will the rotor be in the same position on the compression stroke as the exhaust stroke. Haven't messed around with this sort of thing in 20Yrs - Can someone refresh my memory, please?

thanks,
greg

Hey Tim, thanks for the reply.
did the TDC and the rotor pointed to 11 o'clock and then after a full turn at the 5 o'clock position. just got it running (not well, just running) using 1-8-7-3-6-2-4-5 and
I thought i got the order right now, but still having the original problem which was cylinders #3&4 are not firing (3&4 exhaust is cool to the touch when engine running) - new plugs,wires, rotor, removed points and converted to electronic ign.
Noticed fuel running in on primary side even after engine was off. Lots of wet plugs. Adjusting float levels and firing it back up. Any ideas on the dead cylinders would be appreciated.

Thanks,
greg

Page 9 lists 2 firing orders for RH motors -
1-8-4-5-6-2-7-3
       and
1-8-7-3-6-2-4-5

i assume the cyl #'s are same as ford cars
stb cyls 1234
port cyls 5678

RH = engine turns toward the right when observed from behind.

1-8-4-5-6-2-7-3 - barely ran on this on (still could be a big carb prob that made this barely run)
1-8-7-3-6-2-4-5 Ran better but still getting too much fuel.
Firing order ran counter clockwise.

adjusted floats (hope i did it right) and now I need to go to the parts store to get a replacement fuel fitting and will fire it up in a while. I will try both firing orders again. It looks like the carb has been off a few times. May end up with a new carb and hope for the best.

Somehow I see this moving toward
....The "Question"
..How do you know which is right and which is left rotation
