hello all, i seem to have screwed something up on my Z. when i rebuilt the engine i somehow got the dist. drive in backwards. everyone i have asked said this made no difference performance-wise so i just left it and moved my plug wires accordingly. now the thing that i am not sure about is that it runns a lot better when i have it ALL the way advanced. why is this? i isntalled a schnieder racing cam that requires about a 1000 rpm idle and it seems to run fine with the dist all the way advanced but why is that like that?
