i am trying to get my coach running after sitting for about 4 years. it is idling rough and backfires under load.has hei dist and has been converted to throttlebody fuel injection. i was going to pull the plugs and do a compression test but noticed that the cap is 180 degrees out. it was obviously working ok when i bought it and i havnt touched it since getting it here . just would like to know the reason for this. i assume this is because it is a dist. out of a car and the cap has not been notched to spin 180 degrees. am i correct

Trevor,

While you are under there, check for a 5-7 cross. This does not have to be wires switched. If 5 and 7 are too close together, this can happen.
