	He needs carb body (where carb can be broken down into sections, you can just send body part that has the throttle flap if you like) as he needs to ensure it all fits together perfectly for you. Usually he'll put the throttle flap stem on the lathe to ensure it runs true first then measure everything to make sure the new bushes fit like a glove. I've seen Roger do many over the years (at least 18 years) and many 80/90 members will vouch for the quality of his work. Unfortunately I've also seen people fork out for brand new carbs when the old one only needed a clean, new gaskets and the throttle flap sorted. In fact the throttle spindle is about the only place that wear occurs and Roger's bushes far out-last the original ones. He'll tell you all about it if you ring him.
