[DML] Re: Brass screw and rocker question

["content22207" <brobertson@xxxxxxxxxxxx>]

Have you ever considered replacing your plug wires? Electricity is
supposed to go to the spark plugs, not arc all over the engine. I
think it's safe to say you're not firing on all 6 cylinders.

"On the rock" simply means camshaft lobe contact with the valve stem.
Notice that intake and exhaust valves overlap. This is where the
supposed value of "backpressure" comes from (pulling cylinder contents
out for that brief moment pressure is equalized). It's also where true
backfires (through the intake) come from.

You're not going to hurt anything by adjusting valve lash (make sure
you're at the low part of each lobe), but I suspect your problems are
electrical.

What will fixing them do to your big carburetor conversion?
