Thanks you two.Battery fine as I have it on a trickle charger when not in use. Well here's the next (and last?) instalment. I left it still 'funny' at ten pm last night (after a neighbour asked If I could stop. I guess we don't all like 'thumpers' LOL).Anyway, had a charity event to go to today with one of my stationary engines. Upon return home I went to have another go at the RE. Strange, but it was perfect. Nothing wrong at all. Started second kick as if nothing was ever wrong!!!!!! Weird, very weird.I wondered though as it was a very sunny day yesterday could the tank have vapour locked or something if the air hole in the tank vent was slightly blocked? I don't know, but all is OK now so ?
