Thanks for all your help, the XL is up and running now and I am amazed how fast this thing is..
I went through all the tuning and found I did not need any adjustment from factory setting on the low speed needle for best performance is this normal.
Also the only problem I now have is that...
I am trying to run the first tank of fuel through my new Xl, I can get it started using the roto start but I am having to hold the throttle open manually with my hand to keep it running.
Has anyone got any suggestions as on the dvd the guy just set it to half throttle and it stayed there.
