Okay heres the problem. I have tried everything that I can think of and now I'm looking for some help from all of you! First Its a 4mil cub with 35's,shearers, comp 175 60ft asl. Heres the problem.......Had 158 mains in this winter. temp warmed up and went to 155's ( 48 pilot 1.5 turns out) seemed a little fat with the 158s. took it out this weekend, grabbed 2nd, then 3rd. it fell on its face like it was lean. so I fattened it up on the needle one clip. ran good! rode for a few hrs, let it sit, took off again and it felt like it was lean in the medrange again! AARRRRGGGGGGGG! What the fuck!!! im stumped. I covered all the basics, mic'ed the float bowls, comp test, leak down test.
And now the next problem........I have a digitron (egt sensors) in the cub and im getting a 600 degree difference from the left to right side. wide open throttle i get 250ish on the left side and 900 on the right. I tried swapping the sensors from one pipe to the other to see if i had a bad sensor, but the problem persisted. As for this problem i checked the ignition, and the plugs. both were fine. So if anyone has any other ideas feel free to shoot them over! thanks, Tony
