Sunday :- The carb was cleaned out and everything is standard,the float height was checked again 20mm service limit 21mm+- 2mm.
I can adjust the airscrew to slower idle and also faster and set it so it response is instant when opening throttle quick.
Going to change the plug again cause even new ones arnt allways good.
if that does improve things then ill test the ign coil also.If they check out ok ill take a look at the reeds,ffs friggin hell! that means the carb has to come off again Grrrrr!
