Can anyone tell me the correct ignition timing for my "87 N/A. I have timed it "by ear" and have it running OK, but when I put my timing light on it, it reads like 60 to 70 degrees advance. If I move it much off that setting, it barely runs. I am using a Craftsman light with the dial advance on it. Is that my problem with 3 fires per rev instead of 1 every two like a 4 stroke??? I would like to get my timing to spec., because it seems to have a big effect on high RPM power but that is hard to tune by the seat of my pants!!!!

Thanks for the help!

 

I am not sure what timing light you are using but setting the timing is easy.

Connect to the #1 leading wire and the post on the front cover should line up with the mark on the pulley (I believe it is a white mark) for verification you can check #1 trailing and it should line up with the other mark (red I think).

There is no advance just match the post with the mark.

Least that's how it is on a '86 NA.

 

The rotor only fires ONCE per revolution. Common misconception.
thus, at 9000 rpm, the rotor is moving at... 3000 rpm!
I think it is how you have it set up, or the light.
Are you sure it is one the right plug wire?
