Everything you need to know about tuning, overhauling and solving typical Mini problems with the SU HIF44.
The Mini Cooper stands or falls with one component: the SU HIF44 carburettor. This classic single-carburettor powerhouse determines cold starting, throttle response and pulling power. And as every Mini driver knows: as soon as the jet, float or diaphragm gets old, the magic is gone.
At Carburateur Service Nederland we bring these carburettors back to factory standard every day. No quick fix, no half measures. A complete overhaul means full disassembly, ultrasonic cleaning, checking the float needle and spindle play, renewing the diaphragm and setting it up again to SU specifications. In other words: letting classic British engineering breathe again the way it should.
The SU HIF44 demands precision, mechanically and in the tuning alike: air-fuel ratio, idle, choke response and vacuum behaviour. That is exactly where we excel. The result? A Mini that responds keenly, directly and mechanically honestly again. Just the way enthusiasts appreciate it.
