jimbo349 Posted January 6, 2013 Author Report Share Posted January 6, 2013 iam coming up with 38 Well that would answer my question then as the 25 will be way too small. I better check the others too if you know them as Im starting to think this carb may be off another bike. Although it does run very well.

jimbo349 Posted January 6, 2013 Author Report Share Posted January 6, 2013 Ok been doing a bit of research and my carb isn't the correct carb unless anyone can tell me otherwise. The carb has 2 screws holding both the top of the slide and the float bowl and looking at the online manuals it should have a top similar to a mk2 and the bowl should be held on with a wire clip.....anyone ?
