ok so i took her out tonight for running about and wasnt happy with how it was running, sturreing a few times not really got any power as such. so i pulled over amd looked at the dizzy cap and noticed the guy had marked 2 white lines on the metal infront of the dizzy cap so i turned the cap so the round metal leg was in the middle of the painted lines, tightened up a intake pipe and it runs so much sweeter! no stuttering, has power etc so i guess the 10* setting would work for safety as its retarded , so all good now mate.
