Cur.Bill, I'm going to hit you with an email when I sign off of here. Diesel Dawg, I'd love to help you out too. Maybe what we need is a timing clinic a few of us could participate. I'm not the expert Mel is by any means...actually all I have to offer is having the tools(luminosity) and knowing how to use them. I've set the timing on my truck and gonecrayzi's truck. He and 77F250iesel had talked about a timing get together. He is in DeLand area and 77F250 is in Tarpon Springs. I don't mind going wherever as long as it's within a 3 hr or so drive of Gainesville(I can be flexible) I don't know how flexible the other guys are, we had talked about meeting closer to Tarpon but that might suck for you East Coast guys. Dennis(77F50diesel) has his own timing tools actually a a Ferret(pulse adapter) and I have the old snapon MT1480 with the tools to do luminosity only. Meter does either and gas engines also but I don't have he pulse adapter or pickup or inductive spark pickup.
