the fork on the dizzy is offset...just take it off and look at it....

check to see if theres fuel..if theres no fuel and no spark its the main relay.

if theres just no spark its more then likely something in the distributor (cap & rotor, ignitor, coil)

generally you cant go 180 out ....but i have seen a guy that forced it in there like that....if it isnt going in easy its prolly not lined up right.
