I am not too sure what the year is - where can i check this - I have just ordered a workshop manual for the quad which will help me to do a more thorough check - how can i best check the operation of the choke - is it just to see if the cable is moving the choke pasts in the carb.
My next step was going to be stripping the carb down to give it a good clean - i did have a good look when it was still attached and it looked very clean from what i could see but there may be some dirt inside.
the engine was starting just fine until the bike had a 2 hour trip in the back of a van to get here and then some petrol was added and it has not been starting good at all since that.
Thanks again for the help
