TT/RN/GP Carb Pilot Needle Inner Spring

This is the small coil spring that fits inside the Pilot Needle assembly on original Amal TT, RN and GP carburettors.  This helps keep the pilot in tension and helps ensure it does not unscrew, particularly if the leaf spring is lost or tension gone.

These springs are UK manufactured by us to the original specification

Pilot Needle Assembly With Springs:  It is rare to find an original Amal TT or RN carburettor these days that is still fitted with the correct and full Pilot Needle Assembly.  Originally the design consisteed of a brass threaded piece that screwed into the carb body, which had a special black stained spring clip mounted behind it.  The purpose of this spring clip was to act against the knurl of the Pilot Needle (both the early short type and the later long knurl type), and stop it rotating once set.  Often these seemed to have been removed (they can sometimes make adjustement more fiddly - but are required!), or got rusty and broke.  We can also supply these - Our Item 0157. 

However, the original Pilot Needle assembly was also designed to have a small coil spring fitted inside the brass threaded piece, which fitted around the shaft of the Pilot Needle, and helped apply some positive pressure to the needle when adjusting it.  These are frequuently lost or omitted on TT and RN carbs today.  Again we supply this spring - Our Item 0156.  Both springs are copied directly from original examples.
