Thread Topic: Passed emissions again! Threaded

Subject: Passed emissions again!

HC Loaded 287/400 ppm
CO Loaded .32/4.2 %

HC Idle 400/400 ppm
CO Idle .78/5.5 %

Question is, what can I do to get the Idle HC down? Running a megasquirt and can tune easily. Do I just need to drop the fuel a little?

You could add a degree or two of timing also, start burning the fuel a wee bit earlier and there won't be as much coming out the tail pipe.

Thanks! I'll try adding a degree or two at idle to see if I can get it down.
