Running too Rich...or Lean????
107c.i. TP, single fire, dual coil...Crane adjustable electronic ignition. This just started today...turn off ignition,
get a big engine shutter, then a burp and a big cloud af blue smoke rolls out the air intake.
Too rich, or too lean?
Thanks

sounds more like your timing is off ,any smoke out the intake indicates spark while the intake valve is open .this can also happen if motor is HOT hot (due to a lean mixture) igniteing the air fuel mixture in the intake as the valve opens ..remember in the 70's when a car engine would run-on after the ignition was turned off ? due to lousey gas and retarded timing and leaning out the idle to meet smog ...my 103 10.5-1 with 258 cams will also do this if it kicks back against the starter ...read your plugs for a better handle on the rich/lean also pipe colour and how hot it runs lean = hot and blue pipes
