[QUOTE="joedrum, post: 137193, member: 98"] the pic didnt work ... so i will have to mod the carb i have to do ...and take pic then ... the mod is a hole in the throttle plate of the primary barrel ... the hole i finally ended up with was quite big and is 9/64" hole ...this brings air to the over rich idle circuit as it apply to the small oldwing motor ...this also really changes how to look at dialing in a dft carb in the info weber puts out as how to ...it changes the whole concept of the carb ..... my theory in carb tuning is ...you have to to get a carb to perform at it weakest point ...that being idle and just off idle the best ...if you dont it will struggle to get going ... this mod actually seperates the idle and the off idle response in the combine circuit of the dft ... you can actually with this mod control the idle speed on the dft with the mix crew only and throttle plates completely close over the idle transition holes along throttle plate line up ...weber info is a mix of the 2 ...mix screw setting and idle speed speed screw on linkage ... it also takes some of the dialing info by weber off the table ..as it apply to idle jet size ..and trying to stay within 2 turns on mix screw from close position and also 2 turns on idle speed control after it comes in contact with linkage ..... on the jyd build i am doing now the 50 jet seems rather close ...my method of tuning is to get mix screw to idle bike...this is usually more than 2 turns out .......then see how it responds to off idle throttle romp .......
