gm hei no spark?

We love happy endings. Regardless, we always love it when the OP replies with the outcome. Great you figured it out - another "new ain't always better" result. BTW, the Mopar 1-finger pickup has never been robust. If you buy the Ningbo "ready-to-run" distributor (ebay) you will see the pickup has multiple fingers all the way around, which I expect averages out shaft wobble effect and also eliminates having to set a narrow gap. The later GM "small-cap" distributors have a similar pickup.
