I started this topic to see if I could draw out somebody who had intimate knowledge of these carbs and so far nothing, zip,zilch. Also at the start of the topic I deliberately drew the cam profile backwards expecting somebody to jump all over me about how I had it all wrong, once again not a peep about it. Bumps and I now have the answer to getting full throttle control on these carbs so unless somebody really wants to know I will make no further comment on LM carbs
