dajogejr Posted March 17, 2008 Report Share Posted March 17, 2008 IMO...that's pig fat for the main...it's muddy in the middle and off the bottom. He's got CEL needles, he double checked, but 55 pilots. I told him to try 48 pilots, 1.0 to 1.5 out on the screw....see if that cleans it up. He said it pulled clean and strong on top....

FASTOYS Posted March 17, 2008 Report Share Posted March 17, 2008 John i think your pilots are to big , try around 48-50. The CGL they come with works pretty good for some but if you need richer in the mid go CEL Main should be around the 158-162 range depending on elevation and needle.

RadarRacing Posted March 17, 2008 Report Share Posted March 17, 2008 148-155 main, 145,148 my vote. Look at your plugs at 1/2 throttle for 200 ft. Quote Link to comment Share on other sites More sharing options...
