when you say "with the dist in the right spot" do you mean with the rotor pointing to the right spot? or the adjuster bolt lined up someplace in the middle? Did you remove the distributor and possibly you are off a tooth? On my '85 the cam gears have 3 holes and I have always used the middles. Sounds like maybe you are off a tooth on the dist. Did you make sure to have no. 1 at TDC when reinstalling the cam gears?
