Thanks mate, got it out but took a bit of mucking around. I took the carbs off, got the bowls off and found that one of the jets was seized. I broke the top off the jet trying to get it out but finally got it out with a screw extractor. I got a jet from my local bike shop but it is out of an mc22 not the mc20. He assures me that there is no difference but they look slightly different. The old one is #35 and the new #35S and appears to have a smaller hole in the top. They both fit and are the same length. On his advice I got 2 of them but will they work. I need a second opinion before reassembly and putting them back on. Cheers
