Folks,
After a 500 mile round trip a few weeks ago in my 1959 Austin-Healey 3000, I decided it was time for a tune up in preparation for my favorite driving season (30 to 40 degree top down winter driving).
I must confess that the car has not been tuned up for over 15,000 miles.
I have discovered a strange color to all six the spark plugs. It is a dark reddish brown; almost a rust color.
Any idea what this means as it relates to the air/fuel ratio?
I did discover that at least one of the gross jets for the float chamber was not closing (fuel pump would not stop clicking even at highway speeds).
I have installed new needle and seats, which appears to have solved that problem.
Thanks in advance.
Ron
