Great news finally got the little bugger to start. Changed the plug, fuel and various other bits, cursed and swore at it then talked nicely to it. Then she thundered into life. Not fully sure what the full problem was maybe just lots of small things making a big problem!!!! Next fault is that it won't idle without the choke any clue's? Thanks every one you have all been very helpful. Tim Pull your carb and clean the pilot jet and passage again......It won't run with out the choke cause the pilot circuit has a blockage.....Next time, don't rely on fuel stabilizer either.
