Just playing around with the NT carburettor to do back to back comparisons with my previously installed diaphragm carburettor.
All ready to get the show on the road and head to my favourite "dyno hill", but when opening the throttle i found nothing more than a handful of idle.
Didn't take me long to work out that the throttle cable had broken, and then the sense of fear that streams through a mans body when he prays to Chr*st that the cable broke at the throttle tube and not the carburettor slide. Making matters even more concerning is that a freshly rebuilt engine had been assembled and installed the day before with all the care and diligence of a Red Bull Formula 1 team mechanic.
When i realised that the throttle tube end of the cable was intact i really started to soil my undergarments because of obvious consequences i.e. a solid piece of metal sucked through a brand new engine.
It must have been my lucky day when i lifted the carburettor slide out of the carburettor body to find the cable end sitting on the venturi floor.
This is the first throttle cable (in many) that has broken off at the carburettor end. Typically i get 6,000 kilometers (approx 3,700 miles) out of a throttle cable before it breaks at the twist point of the throttle tube.
I guess today was my lucky day because it could have become real messy at wide open throttle with a cable end going through the engine.
This situation is another example of the benefits of a diaphragm carburettor over a float style carburettor, because the cable inner is on the outside instead of the inside.
