Plugs not wet at all. Just nice and fuel is getting in the carb, but I wish i could "tickle the carb, my 1928 Scott loves a good glug of juice. .......Its just odd. I really wanted another ride today (50 miles on the Silk so far on 2 rides and no running problems except lost tick over)
Bike has good voltage ( I know boyer will do odd stuff if V low) but the battery is on trickle for 3 hours and showing a minor charge. Ill try again in the morning then look at the pick up. I have ordered 2 new coils I know they can be a cause of non starting . Something is flakey, maybe the BIG spark should tell me something. Honestly when it goes it starts easily.
I cannot go back to Luminition as the springs are missing from the Adv/Ret unit and that looks buggered anyway. Pins all loose.and its a v early Luminition
Loads of compression and if you put "easy start" through the plug hole it really should go bang this makes me think ignition despite the big spark
The Boyer wires are a disgrace very very short and stupid thin which means a connector just as it exits the casting. Ill check tomorrow that after a calming ride on my Vin

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!!
