Ok, so obviously I’m new here and honestly it’s been years since I’ve even posted on any kind of forum but I’m desperate for help before I set this thing on fire. OK here goes, bought the bike a few weeks ago, it ran without problems when I picked it up, only problem with it was the rear end needed to be rebuilt, so I spent a good 2 weeks between work freshening all that up, so finally when it was ride – able again, I noticed the carb overflowing. Pulled it apart and gave it a good cleaning, still no good, so I bought a rebuild kit and got to work. This being my first time rebuilding a carb I was very careful and followed the manual to a T. Got it all together, no more leak, idled perfectly but now it would want to fall on its face as soon as I gave it gas. Feeling that I may have messed something up, I brought it to a good friend who is a mechanic (who works on outboard engines specifically) to go through the carb to make sure I did everything correctly. Well aside from one of the jets not being seated all the way down, everything else looked fine and we put it back together and it ran great. Get it home, finshing putting the plastics together, tried running it again a few days later and it went back to running like crap. Well I finally traced this problem to some bad fuel that was left in the tank from the previous owner. I’ve flushed the tank, changed the fuel lines, changed the inline filter, tore the carb apart one more time and cleaned it all out, put everything back together. Started it last night and it idles, and I can give it about 1/8th throttle before it starts breaking up. Every time that I have taken the carb apart I set the pilot screw to 2 1/4 turns out and every time adjusting the pilot screw does pretty much nothing. I’m at a loss right now and there has to be something I’m missing or something else that might be causing this. The only thing I can think is there might be some junk inside the carb that I’m moving around when I spray it down and blow it out but I’m not getting it completely out, which would explain why the problem keeps moving. Like I said though I need help, I just want to ride it and it’s busting my butt instead. PLEASE someone help me!! Thanks to anyone who actually read all of that. Oh and aside from that, I’ve also changed the air filter, spark plug, oil and filter.
