Ok, so I went over to my brother's to help him with his '01 500 H.O. Duck Unlimited bike.
He couldn't figure out how to remove the choke and throttle cable, to replace the carb. By the time I arrived at his house, he had already ground down an old 12mm and got the choke cable out. I had his throttle cable off in about 2 seconds. Once he saw how it came off, he felt stupid, knowing that he can tear down a chev 350, but couldn't get a Mikuni carb off...haha.
So, we got the replacment carb on, and all the fuel lines on, then turned the key. Bingo-bango, a idling polaris in his garage. We put everything back together, and he took it down the street and it runs like it did when he bought it. We noticed that the small tube coming off the bottom of the carb had a very-very slow fuel drip. When we stopped the engine, the leak stopped.
Everything seems right. Normal idle, nice open throttle, back to normal idle. Just that slow drip.
Any ideas?
