318 no start after sitting

I believe so. Unfortunately MSD does not seem to have parts breakdowns, etc, of their distributors.

If you could post some photos, I think we could figure it out. What little the destructions show re: setting the advance bushings indicates that it's a magnetic pickup driving the internal guts.

I did a little web searching, with little results. MSD's attitude seems to be "send it back to us."

I don't suppose it's still under the (on year?) warrantee?
