Ok, existing TT sux. Got it. I'll nuke it forthwith. Funny thing is, though, for being such a crappy TT, There's a bunch of trucks with valves adjusted via that method that keep showing up at Winchester year after year without blowing up so it can't be too terribly wrong....

Jerry -- I'll make you a deal -- Come to Wrench Fest and besides picking up a couple of engines for your collection, we (um, *you*) can go through this procedure from scratch for a whole new *Professionally* written (um, that would be where I come in

) Tech Tip that doesn't stink and isn't plagiarized (the term you were looking for above

I've also been kicking around the idea of trying a video TT... this could be the one to start with.
