Engine not idling right

[Jezza_hr]

After some toying around at a little tweaking, it seems the engine is now running sweeter than it ever did. The initial starting of the engine is a little sluggish unless you let a little more air in the engine, but once it's going it's as sweet as a nut. I adjusted the idle, had it running for a little while longer and the backfiring just seemed to clear up. My impression is that it was either carbon deposits that needed clearing or the fuel pressure regulator has eased off and the pressure has come back to normal.
