Ok first off thanks for any help that I get on this. I have an 09 raptor 90 that I am having issues with. I have had it at the shop many many times, more times then my daughter riding it. I was told that the carb and jets are getting clogged. I have drained the carb and checked the jets and they appear to be free of any clog. ( just looking threw the holes right?) Well here is my question. I am able to get the quad started, but it has to be wide open choke. When I hit the throttle it wants to bog down and stall, sometimes the only way to get it to go is when its on wide open choke. How do I know when I have the correct settings on the throttle screw and idle screw on the carb? Is there anything else I can do to fix this issue. Thanks again.
