Welcome to the joys of owning a Silk!  I guess you checked petrol was getting from the tank to the carb and the top hat filter in the carb banjo is clean.  Also you have compression.  I have had problems with petrol taps passing and partially flooding the engine.  Had to kick it over for quite a long time to clear with a wide open throttle, plugs were very wet. The inlet passage and transfer passages are sealed  from each other by silicone sealant under the inlet cover.  If the sealant breaks down for any reason air/fuel mix goes round in circles instead of to the combustion chamber.  I made a thin paper gasket sealed with Welseal and have had no starting problems from that source since.
 One last thought-has the timing slipped?
Hours of fun to come!!
