After all the help from people on the list and a lot of calling around,
I've located a head for a reasonable amount and it's supposed to be
here tomorrow. I'll let the list know how it seems when I get it.

I've got everything in hand. Parts are cleaned, holes retapped and
threads chased on most things. But I have two questions:

1. How far do I turn the tensioner when re-installing the belt? I ask
because of conflicting opinions. And what's the best way to turn it if
I don't have the tool, a screwdriver stick between two drill bits or
nails that fit? (OK, I know that tuns the questions up to more than
two, but it's related).

2. Anything special I should know about injector installation beyond
fish out the old heat shield, drop in a new one, and tighten away?

Thanks,

Jim
