OK looks like I'm going to have to buy a new timing light; unless someone returns the one I loaned to someone (unknown or at least I don't remember who) at Road Atlanta in the spring. I've been looking at the Equus #3555 which I think is an older dial version or the #3568 which is newer digital verson. $45 or $65 on net. I will be using it with Electromotive HPV1. I had a Craftsman dial type which I have used for years without problems. $70. Recomendations?
