Well, I read a few threads on here about adjusting the alda for less smoke. My car HAD an almost constant stream of smoke, so I figured adjusting the alda was a good idea, as many attested to the positive effect it had. I popped the plastic cover off, then tore at the surrounding metal with needle nose pliers until I had room to get at the lock nut. Loosened the lock nut, turned the screw (why FLATHEAD, WHY!) 3/4 turn ccw, then tightened the nut back up. Then I proceeded to drive home. Immediately I noticed a significant decrease in power. There was definitely a significant decrease in smoke, but a REALLY significant decrease in power. I got home and popped the hood, figuring I'd tighten it back up because I'd rather have smoke than no power - by the way, I thought ccw increased the richness of fuel, thereby giving you MORE power?? When I loosened the locking nut, the whole screw, metal surrounding, and washer came out and fell onto the street. Not having any clue as to how much it should be screwed in, I just screwed it until it wouldn't go anymore. (a true understatement) I figured I test it, loosen it, test it, etc. After I screwed it in as far as it would go, I tested it and had virtually NO power. So, I went out to loosen it, and, here's the kicker, the STUPID FLATHEAD SCREW is stripped. It will not budge. So now it's stuck with no power. What do I do??? I really have no idea at all what I can do at this point, besides wake up early and take the bus to work. Please, help!
