Blue Bird. Does Canada Get Hot?? LOL. We are at the peak here 95-100 degree with 90% humidity.

I totally AGREE with the timing. I have Ruled soooooo much out that It is the only varible. My timing cover must not be original because it has NO numbers just 3 lines. I have it to the top which going by the above picture would be 0 I know for sure it needs to be between 9 and 12. It also does seem to run better with full manifold vacuum.

I will post a picture of my timing cover tomorrow

but you have to admit these electric fans look good for FREE right!
