Well we tore into the carb once because it was running to rich, i was getting horrible gas mileage and a dead spot i felt i had to throttle past at 1/8th to 1/4 throttle. Also, it was coughing a lot while cold at low RPM. This is what we found in it. Pilot - 40 Main - 180 (with the clip set way rich) We changed the pilot to a 42, and moved the clip up the needle (dropping it) two notches to lean it up. And after running a couple hundred miles it seems to have helped somewhat, but i don't think its right just yet. Here is what i'm looking at. The plugs seem awfully lean, the dead spot seems to have moved up the RPM range... and it seems to want to surge when i roll on/off at about 1/4 throttle. (65-75mph mainly) Also, no popping or coughing while i start now, but i've noticed after a decel, and roll back on it studders once, then goes. (i'm guessing, but would say at 2500ish RPM and low throttle) Like my cough is back, only in a different place. I want to tear into the carb again, and i'm thinking i just overcorrected, and need to richen it up one notch. And mabye go with a bigger yet pilot. The plugs seem to read lean, they are awfully white. Any help would be appreciated, or suggestions before i get in there again.
