[QUOTE="Matty, post: 47721, member: 1339"] Hi All Thanks for the good advice. The plot thickens a bit however, because I put the new float back - to check the levels again and the bike now seems to run very well !!! I must admit that it seemed to run OK for a week or so when I first changed the float, slide, needle etc. but the problems appeared with the onset of the cold weather, so weak mixture seemed to be the cause. I now think that some piece of "grot" had got in somewhere and with draining the petrol from the carb. for my tests etc. it has been flushed away !! The petrol level is correct with respect to the pilot screw with the new float and I can confirm that my carb is 1-1/8 bore and the proper one (the bike had only been used for 2 years when I bought it, so I would be surprised if it had any non standard bits.). Can any one confirm please that the needle and needle jet for a 289 sent by VOC spares are the correct ones for my Series C Comet carb. By the way - the plastic float has a clip which is designed to fit into the lower slot on the new needle - the upper slot is a fit for the old brass float type of clip. If you use the upper slot with the plastic float it hits the tickler before the petrol is cut off and just floods. Also because the float clip is non adjustable it is not possible to change the float level by shimming. Thanks again - and I hope this is now put to bed, but I may add more to the thread if mixture problems persist or the exhaust glows bright red !! Matty [/QUOTE]
