Ok, so then YOU verified tdc YOURSELF? I don't care WHO assembled it. What I'm getting at is if it's not been verified and seen by then end user who is checking timing.....that's YOU, you will not be 100% sure where your timing marks are.
I make that point, because it seems to want a LOT of initial timing and you want to be sure that's correct. Sometimes that's the case, though. I've seen a few like 25* initial. It's rare.
Then of course, there are those who lock timing out to "whatever" the total is. 32, 34 , 36....."whatever"......but I don't think that's what we're talkin about here.
