OK, I just read through 15 pages of bullshit. In a weird sorta way, I'm gonna stick up for the kid. Although there are many very intelligent Banshee tuners here, how many of you were changing carb jets at 15? Hell, when I was 15, I bought new sparkplugs for my car because they were rusty on the outside. Yeah, he insisted it "ran fine", and cousins uncles whatever said it was fine, but nobody here thought to tell him to check and see if the slides were in backwards. He figured that out on his own. Give him some credit for that. I personally have never put slides in backwards. I saw it on BHQ where someone said, "All I did was cleaned the carbs and now it runs like ass". Someone mentioned the slides and sure enough, that was the problem. That got me to thinking, sure enough, that makes sense. If the cutaway is towards the motor, the non cutaway side is going to act like cupping your hand over the carb and creating a much higher vacuum at the needle jet and sucking in more fuel. This fuckup only occurs on stock Banshee carbs. Nowhere else on the planet, that I know of. So, in diagnosing someones problem, sometimes it's hard to visualize what kind of stupid mistake someone could have done to CREATE a problem that doesn't occur naturally. You've got to give the kid credit for trying to fix it. A lot of people would have just said, "screw it, I can't figure it out. I'm just gonna buy another set of carbs."
