I purchased a carb for a pocket bike to see if it will fit into the Mixte frame better than the original Gen II Chinagirl carby. It certainly is a physically smaller carb which is good and the fuel tap is on the carb body itself which could make life easier too.
There is something else that I'm wondering about, - there is no heat spacer block on the Chinagirl intake manifold. Is this normal? - looks like it could be a source of problems to me with the carb getting too hot and vapour locking.
