Mike,
You are right. The top of the fan moves from the passanger side to the
driver side. I placed a leaf on the outside of the radiator and it was
sucked into the radiator and stayed there. Also I felt air moving back over
the motor from the fan. I also learned that the spark plug wire can put out
quite a poke if you touck it when the motor is running. It is now raining
and boy did that sting.
Do you think that the numbers from 25 to 60 at each spark plug is not from a
compression test. What should these be for the 216?
I am using about 50/50 - it gives me about a -10 rating when I test it.
Thanks AGAIN!
