i have removed the tank and now will be looking into trying to find the cause of the problem. i have found the breather tube and traced it down to the tip over valve, a small black plastic thing in the middle of the tube, i hope thats it anyway. How can you test it is working ok and do you realy need it in there.
I have blown down the tube and you can feel air at the bottom, but when you suck on the tube it seems to start and then seems like the valve shuts off not allowing any air up the tube. does this seem right ? .
will also check out electric connections to while im at it any tips here also.
oh, pulled the plugs today as well and they seem a bit on the burnt looking side after 5000ks but still spark ok , (dont know if that will shed any light on the subject) re vent or elec problem
Thanks chaps
