SU Carbs - Connection, HIF type

Although there are a number of different versions of the HIF type carb, they all essentially share the same type of connection layout.

The diagram below depicts the most common type - the connections can be on either the right hand side (as illustrated below) or the left hand side. Some have the connections shared on either side. Whichever, the port functions are the same. It isn't essential the crankcase breather pipe be connected - you really don't want that choking crap from the crankcase spoiling your nice, fresh, fuel-rich incoming mixture - but it's obviously essential to block the port off if you don't. A blob of RTV Silicone is sufficient in most cases. To adjuster mixture - screw the adjuster in to richen, out to weaken. There may be a 'anti-tampering' cap in there on some carbs - just hook it out.

I have been monitoring radiators and their development since the late 1960’s because they were and still can be a problem when tuning cars.
I have seen, tried and tested everything made available or offered to Mini Spares

A desire to solve induction installation problems and assist in the choice of induction types for many ‘A’ series applications, led to the production of a new range of Manifolds from Mini Spares, London, to mount on the ubiquitous SU carb of various types and sizes.

Despite numerous manifolds being available from many different sources, there seem to be three times as many problems when...
