I change my spark plugs each Annual, get the
old set tested, cleaned, regaped. #4 is a real Bear, # 2 a little better
but not much it will take as much time change #4 as
it does
to change all the others. I was at Harbor Freight
the other day and found a socket that makes changing #4 easy.
The socket is a 7/8 Vacuum Switch Socket item
95047,
it looks much like a Spark Plug Socket except it
has 1/3 of
the side cut away which lets it slip over the plug.
Works
great.
