Listed here are reproduction parts to fit Amal Remote Needle (RN) carburettors. These carburettors were fitted to the racing versions of SOHC (Manx) Nortons from the late 1930's, through to about 1951 when they were replaced with the fitting of the GP1.
In Amals racing evolution, these carburettors were like an interim version of the GP carb, in so much that Amal had realised it would be a good idea to move the needle away from the choke area, so as not to obstruct the airflow, so giving the name 'Remote Needle'. In practice, it was found that the route for the fuel flow from the needle was not perfect (so I am led to believe from the literature I have read) and therefore they were more fickle to tune than the more common TT carb. However, they were found to give better results on 'out and out' fast circuits, which presumably the Grand Prix bikes were more likely to encounter. Clearly, Amal's thought they were on the right track, because the GP1 carb was similar in concept, however the fuel routing was improved in design.
As a footnote to this, I remember when I started racing in the 1980's that RN carbs were quite common on peoples shelf's because they were considered rubbish for short circuit racing, and no-one wanted them! I certainly remember turning up my nose at a couple of them, even though they were dirt cheap - - - not so now!
There seems to be very little information available for Remote Needle carburettor, and the parts specific to RN carburettors are now extremely difficult to find. This section offers some of the parts specific to the RN carb and I am also looking to have many of the other parts made in the future - including the RN specific needle holder that screws onto the side of the TT slide. Please note though, that these parts will be comparably far more expensive than the TT parts, as I am having them made specially in much smaller quantities than the TT parts.
