Hi,

I removed my spark plugs from my 1944 Ford CMP (V8 flathead) for inspection this morning and took note that some were a nice grey/tan colour .... and some were Jet sooty black !! (Not wet shiny black but dry Matt black)

I'm not sure what this could indicate? .... if my carburettor was too rich then would all Spark plugs be Jet black ?

Can anyone kindly help?

Kind regards
