Did a bit of work on the RT1 and the slider today, sliders pretty well ready to go, RT1 running rich I had a bit of a charge 'round Friend Hal's paddock last Saturday. Needle's all the way down float level looks ok, "O" ring on the needle jet is ok.
Local Yam. dealer can't get a new needle jet or needle, The main has had the size filed off so its probably been drilled, but they've ordered one in for me.
I have another carby with no slide or needle so I'll put that one together and see what happens probably tomorrow
Roll on 9Th&10Th Aug. cheers
