Re: Setting Timing On An EVO

Did this just start or did you mess with your timing? It doesn't idle, but how does it run? If it backfires through the pipes-check for exhaust leak. If your carb is "coughing" then it's probably lean. Idling issue is usually an intake leak problem. Use a carb cleaner and spray around your manifold. Does your idle go up?

I doubt that your electonic ignition is causing this, although it can.
