Series 1 180...conked out, now won't start

Thanks. Very interesting.
Have had another go at it thisarvo.
Could it be an incorrectly routed choke cable, giving a stupid rich mixture even when the choke appears open? Has this happened before?
 
FINALLY...

...re-routed the choke cables and now it runs like a dream.

Thanks to everyone that helped.
 
Just as I thought it was all over...
Confident that it was a carb issue and because I hadn?t bought a new set of plugs, just experimented with old-but-still-good sets, I treated myself to a new set of Denso W24ES-Us as recommended by Steve.
Result was not a dicky bird?s chance of it starting not even a cough, pop or splutter. Gone back to an old set of NGK 9EGVs and it starts on the button. Will these be OK? They?re racing plugs really but 9 temperature rating so I can?t think they?d cause any damage, will they?
 
B8ES, don't bother with the precious tipped expensive plugs. 9 is pretty cold. The 9 was the recommended plug for big hard long speed runs, I don't know anyone who uses 9s even in Oz where it gets bloody hot.
 
Just had a bit of a bicker with the supplier of the Denso W24ES-Us...I don?t think he believes me and as they?ve now been used I don?t think he?s going to refund me.
The 9EGVs were in stock, so they?ve cost me nothing

How very bizzare !??.....whats that all about?
 
I've heard of dodgy plugs and crapola copies, but not even a whimper?? From a brand new plug???  :-\

I'm just so grateful that I never had even one problem with fouled plugs on my SF. Can anyone explain why a triple is so sensitive in this area? I started with the W260T2 Bosch units way back in the early 70s, then went to B9ES NDs and have no reason to ever change. As long as I get the genuine article! I found a NOS 1970s Bosch plug in my spare parts box yesterday! Maybe rivet counters would like to buy it  :-* :-*

I think you nailed it, Vince.
After two weekends of testing it appears, on my bike anyway, that Plug temperature rating is crucial. The two sets of brand new 9s after being run just once and left to cool, both never worked properly again. I cannot think that even I?d be unlucky enough to buy 8 duff plugs.
So fitted and swapped 3 sets of 8s and after allowing them to cool, they all re-started.
When tried the same experiment with 9s, all failed the same test.
God knows what I?m going to do with these 12 NGK B9ESs?
