Thanks to both of you,but I have tried both of those fixes. I did a compression test on all 8 and each one had and held at least 170. On the timing I was running 36deg advance and backed it to 30. Still the same thing. I talked with a guy the other day who said the plugs I was running may be too hot. I do not know enough about the difference in a hot and cold plug. Any thoughts on that???
