I had to go back in and recheck it as it was still flooding. Once I fixed that problem, I did Serowbots test and determined it was, indeed, the petcock that was at fault. I got the rebuild kit and installed it. Bike did the exact same thing. Yes, I replaced the vacuum lines too. I didn't have the $ for a Raptor at the time, so what I did is I removed the vacuum line altogether, plugged the carb end and the petcock end of vacuum line connection, and I put it on prime. I have been happily (almost) riding this way ever since. No flooding, no stumbling, no dying. And I don't shut it "off" when parked. (so I know the needle and seat are working properly) I may get a Raptor someday, if I have the bike long enough.
Ok, if the carb was flooding while running, it is not coming thru the diaphram. It had to be coming thru the float valve.
But you fixed that. Then the diaphram really was bad ? But yet the valve was still holding open w/ a leaking diaphram ? But yet,...........
Tell ya what, I'm leavin this one alone,....it just isn't adding up.
