Hi I was wondering if anybody could help I have A 1976 340 liquifire and it needs a cdi but it is not on there it just has a plug not the two round plugs. Does anyone know which one is the A and which one is the B? thank you.

goatman,
The square plug type is the B style for the cdi connection. This link shows a picture of the B style.

goatman,
If you know how to use a ohm meter, use the previous chart to test the stator and timing ring.

I do have a meter. I paid 75.00 for the sled from a lady her friend works for a jd shop and he took the cdi off and told her it was bad. the sled is in very nice shape.

If you are not stuck on using OEM parts, buy a Hewtec FirePlug cdi. It is better than original.
