Triumph Repair: tuning 1500, air fuel mixture, hex head


Question
I have just brought myself a colourtune kit as it worked wonders on my friends mg, where on my 1500 SU's do i find the screws to adjust the air / fuel mixture?

1980 TR Spitfire 1500 twin SU

Answer
Thomas,

If your car is still fitted with the factory HS4s then the adjuster is in the traditional SU location... the hex head around the jet assembly at the bottom of the carb.

Just be careful not to touch the hex head up against the carb body.


Cheers,

Jim
