I sincerely apologize if this has been covered before, but i really have no where else to go.
i'v searched as much as i could before posting this, because i hate people posting questions when it is so easy to find an answer.
Well my case is, a 72 510 with an L18 swapped, clean and rebuilt motor with weber carbs. I drove the car with no problems what so ever, decided to install an oil cooler for the summer (texas summers get really hot). drove it home from the shop. next morning hopped in to go to work and all i hear is back firing from the exhaust and even fumes from the intake.
after checking everything, i realized that the dizzy was loose! i could turn it left to right fairly easy.
after tightening everything up, the engine kept back firing.
Things i'v done to troubleshoot:
-set it to TDC
-Made sure the spindle is at 11:28 with the narrow side facing the radiator.
-Rotor facing the radiator aswell.
EDIT: car won't start
basically followed this thread "http://community.ratsun.net/topic/6072-ignition-timing/"
this car is my daily, and i have no clue what should i do :(
