Ran poorly, but got about 25mpg. I had the car running good, but rich. Leaned out the low speed jet a bit too much for the trip. The interesting thing is that the lean condition would be followed by running rich at about 2,000. Also developed a big throttle sticking problem. But that may have lead to a better tune. While the engine was idling at about 2000, I noticed it was pig rich. Very lean at idle, rich at higher speeds, way before the main jet kicks in. So I adopted a different tuning regimen. Instead of selecting the low speed jet based on throttle closed, "book" tune, I went to a bigger jet and set the idle richness for stoic at 2000. This gives a slightly less than optimum idle, but is okay. It also produces a leaner tune at low speed. The big surprise, it helped the lean condition when at speed and WOT. I settled on a low speed jet that is two sizes larger than I had been using. Runs better, no hesitations, cruises leaner and helps the WOT lean "hole". I then leaned out the main jet. I'm currently two sizes smaller, would like to go even smaller, but the WOT hole got awful. Fiddling with the air bleed. I've found that zero air bleed is not the solution. Installed a jet with my smallest drill size, .023" . Not been able to test it. Will go up by 4-5 thou steps, trying to find the magic size. BTW, my current low speed jet is .0295" and the main jet is .043". Will have to go to .046" if I cannot solve the lean problem. .043 still gives a rich reading, about 850-900mv. .046" produces readings of 900mv+. The size for the trip was .051", very rich. These are level cruise @ 3,000 - 3500.
