Hi my lightning is equipped with a roto start ([:'(])and is very difficult to start (it has the .26 engine) , the lhs gave me the roto start setup when to pull start broke and told us the shaft will work in a normal cordless screw gun that didn't work and we found that a air gun (tire changing type) does spin it fast enough but after starting it it will not start again for a few hours and the AA igniter needs new batts every time for it to start. Also i would like to change the front/rear torque dist. how can I do that and finally, does anyone know witch screw on the carb does what ? thanks.
