I'm absolutely stuck at this point and have no idea how to move forward which is very frustrating. I bought the raptor around 4 months ago from a trusted friend. He had issues with it similar to what I'm experiencing now but after I bought a 50$ carburetor and installed it, it started up within 2 seconds. Well 3 weeks went by of riding for hours and having no issues at all. This week I unloaded from my truck and immediately had issues with it not idling, similar to before. I had thought this was a carb issue so I have taken it off several times to clean, and I mean clean everything including each jets. I also replaced cdi, spark plug, and i have no idea what else to do. I've considered buying the offical oem carburetor for almost 400$ but I dont understand why that carb worked fine for over a month. I can get it to start, it revs up high then cuts off. I've must've spent 2 hrs adjusting fuel screw and idle screws. Please, please any advice appreciated.
