there was nothing wrong before I got my big fat fingers on it! I did also change the fuel filter so that's maybe put air into the system and caused the sensors to think the tank had run dry. according to the manual the tank running dry causes this light to come on and they also say it should clear itself after half a dozen starts.
its been a few years since I last tinkered with an engine and certainly none with the odd layout this has but it was nice to be elbow deep in oil again!
