Ok thanks for the vent and vacuum port info. I actually did not have to bad a time installing the air-box, boots on box, make sure all tubes and wires were out of the way, then I held the air-box as far to the rear as possible, and tightened down the mounting bolt good and hard so it would not slide forward. Then just took my time, and kept my eyes om all 4 of the air-box boots as I worked the carb rack into place. It really went pretty smooth. I was certainly glad that I took the time to seek advice on installing the air-box, it saved me lots of frustration.
Speaking of frustration, now that its back together, I have no power to anything at all, (you gota keep laughing) my manual (16-2)) pretty much says if its not the battery or it's connections then its the ignition switch or the "main fuse". Page 18-1 shows a 30A fuse in the starting circuit, but that is not a "main fuse", although I would like to know where it is. In my wire harness, about 6 inches forward of the battery, on the left side is a large object completely tapped up, inside the harness. I have thought it was some type of resister, might this be a "main fuse" ?
thanks for your help
