Cable has been replaced, and I soldered a nipple onto the end of the new cable.

All going  well til the throttle jammed shut (looks like a burr on the jet) and I remoed the newly solded nipple....
the only wway to release it all was to stick a screwdriver in throgh inlet, and I managed to take a chunk out of the edge of the groove so the cable will now no longer stay in place !  
 
 
Hey ho.....
It did sound good when it was running though !!
Cheers
