i put some new fuel in. 5ltrs of bp ultimate and another 5to go in later. The thing is the fuel gauge has now gone right to empty with the light on but surely 5ltr's is enough to get it going???? I took the plugs out and they have spark and there fuels getting to that metal bell shape thing. I even blown down the return and opened fuel cap to get any air out so fuel shouldnt be a problem. If there was a prob with the dizzy or rotor arm, would i still get a spark. It must be something to do with the ignition system unless it just needs another jerry can of fuel!?
