[DML] Re: Brass screw and rocker question

["stainlessilusion" <5n-@xxxxxxx>]

Thanks Bill for your reply. Let me explain a little...I'd like to have
the engine running good with the FI setup, that way; should I ever
need to install it again I know it works, Or if I sell the setup to
someone, I know I'm not giving them something that is junk. OR, if I
can't get my hands on a manifold I'm not totally screwed with nothing.
The wires-brand new 8mm from special T, problem is that the contact
between the wire on the cap and the control unit wore the boot down a
little, so that was the only wire that was sparking-now fixed. I ask
about "On the rock" simply because-when I was doing the valve
adjustment (they are already done) and the book said the #5 should be
on the rock-I imagined that the #5 rocker would be on the camshaft
lobe.-----Dani B. #5003
