I do all my own work but I met a chap in Crowthorne near Reading who has a neat nc35 with sticking carb floats but his local bike shop won't look at it till winter so I said I would ask for help here. Any suggestions?

Probably a bit far but you could try the Bolney motorcycle workshops (Just south of Gatwick). His son races a NC30 and it is always immaculately presented and goes well.

If he gets desperate he can always take the carbs off and sent them to some one who knows how to sort out these carbs (Graeme France, Rick Oliver), but that would be a last resort.

Thanks for the suggestions, all towns should have vfr workshops!
