I am convinced the dizzy drive in my car is off 180*. Motor is at TDC, verified by the valves, the timing mark on the fan, and flashlight in the #1 spark plug hole.
Currently the rotor points away from the driver and the only way the Dizzy fits in the car is with the back of the rotor pointed at the notch in the dizzy. I don't mind leaving it this way, but does anyone know if it will affect the synchronization of the FI points? |

It will run like that as the triggers fire every 180' of crank rotation. I will it run better if you flip the dizzy drive back to stock.

Why would it run better flipped back? It seems to me either it would work or not work. I'm just curious what the difference is.

It will run the same either way. I'd probably fix it IIWM also, but you don't have to.

(IMG:style_emoticons/default/agree.gif) I ended up installing my dizzy 180 out while trouble shooting (fuel problem after all (IMG:style_emoticons/default/dry.gif) ) and it ran great. |

Well, I successfully re-indexed the drive either way. It was kind of bugging me that it wasn't right. But, I didn't want to F- with it, and drop that washer in. I used a 7/32 allen socket on the end of a nut driver which fit just right, to pull and turn the drive.
