Disassembled IDA with new bearings, new chokes (34mm, better for my small 35,5 valves), F11 emulsion tubes...
My run with bad jetted Weber IDAs and not full open IDAs butterflys..the linkage have to be changed...But all the way with that problems a 16.2s is ok...But compare with my 15.5s last year at DDDay 07 to slow:-(
