I may have forgotten what side the magnet should be set,and i watched a YouTube video of someone doing it wrong, and i still got it wrong,
well i am still playing with carbs! I am using the ft160 throttle slide in a asp fs120 carb body with the 120,s hs needle in place still.. pics of the throttle at idle and peak


..after more tuning and almost another litre of fuel, ive been busy,probably need ear muffs! But i think its running very well ,not using any exhaust pressure, i think the rings are starting to bed in
the head temps have all of a sudden dropped a fair amount and it splutters less through the rev range, will drain the wase bucket and monitor that through some more running ,
i have been using silkolene prokart oil its a mix of easter synthetic and castor oil
