Re: Spark Plug Reading
Is this indicitive of all plugs? The plugs seem 'normal ' heat range and your Holley 94 seems to have the standard 51 jets for sea level area. hows the power valve size?
how does it run at idle. Is the air cleaner clear.
as stated it shows carbon fouled, does it use any oil.
The porcelain looks the right colour, tan coloured.
Verify if all plugs are this condition before any 'fine tuning"
