It seems that as long as I've had my '53 TD the spark plugs have fouled
on a regular basis. Last summer I had the carbs professionally rebuilt
and adjusted and expected that to solve the problem. But today I tried
to drive the car and it was running so rough I turned right around and
went home.
I pulled the plugs and found #3 fouled (black material between points)
and #4 somewhat caked with black material but not fouled. #1 and #2 were
black but not so bad looking. This is pretty much the same thing I used
to see before the carbs were rebuilt.
Carbs were rebuilt last September, 1300 miles ago.
Plugs were new last September, 1200 miles ago.
Ignition wires were new in 2007.
Distributor cap, etc. new in 2004.
So I'm wondering what I can do to reduce this fouling? Would hotter
spark plugs work; I'm currently using Champion L82YC. Would a sport coil
help (hotter spark)? And if so, I believe the plugs have to be regapped;
to what setting? Currently they are gapped between .020 and .022
according to the book.
Thanks for any help.
