I know that my mate, the previous owner of my 3.5 Sport, had been having starting dfficulties and had replaced the ignition transducers, but I reckon I have uncovered the real problem during its overhaul - the short-reach plugs would have efficiently hidden the spark from the fuel wouldn't they?
That's going to be remedied, though I will run a well greased plug tap down the threads to remove any carbon that may be lurking down there. He'd also replaced the plug caps with NGK SB05F ones. My previous experience with British magnetos suggests that a non-resistor plug cap would be preferable along with copper cored HT leads.
I found a reference on this forum to removing the resistor from the NGK job but so far Ive not found a way that it can be done. Similarly my search for a similar cap even with a 1 ohm resistance has revealed that they are available in Spain, but for collection only
Any suggestions gratefully received.

How many times did Saturday Night at the London Palladium or the Black and White Minstrel Show disappear into a snowstorm as someone rode by on his James Comet or BSA Bantam on his way to the pub? 
Try doing that trick with a Matchless 500 single! Over the next day or two I'll get the bike run up to temperature and change the oil and set up the carbs properly.
