Hi Bob, I did not make the carb,or the manifold ,as drawn. I tried several carbs and ended up with one from a Super Tigre engine, bought second hand on e-bay. Had a lot of fun getting the carb to work as I wanted. If you access the Modelel Engineer Forum and put my name in the search box you will see photos of my Vee- Twin. I am having problems puting photos on this forum at the moment.
