here below my timing advance and afr table
i have been playing around with more or less timing without .. no change .
problem remain the same , above 3000 rpm it take times to get up in rpm...4300, 4400 rpm has been the max at wot
one time i tried with more gas i didnt see any change . I will try -again- this week end with more gas and will look at the plugs

i did a vacuum test , and at idle i see a steady 20'' of vacuum
