I came to start to Bullet the other day and - no compression. It didn't take long to find the problem as the decomp cable was sticky and was holding the valve just off the seat. Having got the cable off to lubricate it I got to thinking (dangerous I know) "Do I really need a cable operated decomp" I decided "No, not really" So I did this;
It's now quite easy to reach down to operate the decomp. by pressing down on the knob. That's one less cable to worry about and a bit less clutter round the 'bars. The spanner flats are for taking the knob off so a box spanner will fit over the whole lot (much easier than before) The knob is one I had in the bit-box and I'll look out for a more suitable one. Somewhere I've seen one with a nice concave top which might look better.

Yes Alan something like that but a bit bigger perhaps.

The other added bonus of a knob is if gets stuck open by a bit by a bit of carbon so something then you can just turn it back and forth to clear it.

---------- PLUS}-- you can now remove the whole De-comp. unit just like a spark plug as that stupid cable adjuster is no longer there !! How about using some stock hexagonal brass?.. This will automatically give you those "Spanner flats"..

I've not had the decompressor cable on any of my Enfield's. (All three.) I just push down on the top of the valve. When the engine's hot I just have to be quick! Ouch. Ha. Maybe a knob on top is a good idea.

Well Alan R, hex brass would have been better but I had a bit of round brass and a file.....
And I AM a Yorkshireman

I too am guilty of running a cable-less decompressor... although I am not a Yorkshireman, my team is Leeds!
However, I have been "toying" with the idea of something like this as a kind of knob
It's either that or a miniture Ganesh figure...
