SU Fuel pump, FUL117 for the Morris Minor
Created: January 30, 2000
If your pump came to you with a warning label advising that Correct Polarity be observed, this sheet is for you.If you have converted your car to negative ground, and if you have a pump marked as above, you must also modify the pump to work properly with your electrical system.
Carburetors Installation of HIF-6 or HIF-44 Carburetors
Created: January 29, 2000
The HIF-series carburetor differs from the HF-series primarily in: 1) The design and location of the float chamber, which has been incorporated in the body of the carburetor, and 2) The introduction of temperature-sensitive mixture control to compensate for varying fuel densities resulting from changes in fuel temperature.
Synchronization of Twin SU HS-type Carburetors
Created: January 29, 2000
Before proceeding to synchronize your carburetors and for best results, some preparation is in order. Your carburetors should be in peak condition with no play in the throttle shaft bushings. If these bushings are worn, synchronization is difficult or impossible to achieve since there will be a vacuum leak past the bushings.

SU CARBS - Dashpot oil.
Created: September 29, 2000
This subject is a regular message-board poser. Many of us have touted our preferences and discoveries whilst playing about over the years. One problem with trying to deal with it on the message board is the sheer volume of information offered and available against the time available to post it.
SU Carbs - Quick reference needle selection
Created: September 08, 2000
Being an oft-voiced question on the message board, I thought I'd share it with you. Since there is already a very good source of starting points/applications for fixed needle carbs, this is for those floundering about in the wilderness that is the biased (swinging) needle example of the breed.
SU Carbs - HIF, a more finely honed instrument.
Created: September 06, 2000
The basic SU design has maintained the same basic format since it's inception. But modern technology continually sweeps its ever-growing arm across all manufactured products and the SU was no exception.
SU CARBURETTORS - How SU Carburetors Work
Created: September 01, 2000
Even though the SU carburetter (carb) is a very basic yet precise instrument, some fundamental understanding on just how it works is needed to be able to deal with common problems and tuning. Following is as basic a description of what's going on that I can manage!

Classic Mini Cylinder Head - Unleaded Fuel Use
Created: May 16, 2001
The specter of 'unleaded fuel only' - instigated in UK on January 1st 1999 and seemingly from decades ago across the rest of the world - seems to be forcing more and more folk into frightened, panic orientated action.

How to pick the correct exhaust manifold for Classic Mini Coopers
Created: September 28, 2000
The third stroke, that following the compression stroke, of our four stroke Mini engine is the only one producing power. The other three consume it. Here we’re looking at with exhaust manifolds, so what we need to consider is how to minimise power consumed on the exhaust stroke as the piston pushes the spent gases out.
Project Small Bore, Part 2: Cylinder Head
Created: July 24, 2006
Last time we started building a small-bore engine for maximum power. But there is no point having a good engine and putting the wrong head on it. I'm going to use the 12G202 head, as these are the best to modify for our purposes. They are a bit smaller than the 12G295 or 12G206 heads, which gives you a bit more metal to play with when grinding. As far as a standard head goes, you can't go past the 12G295 or 12G206.
FUEL - Leaded/unleaded fuel and the alternatives.
Created: September 29, 2000
The fuel situation seems to be worsening at a great pace these days. And as is exhibited by the questions that appear on the message board many folk are confused by what they can and can’t do, and what is best to do as far as race engines go. Many have posted (particularly from the States) that nothing need be done - just run on unleaded.
A Basic Guide to Electronic Fuel Injection for Minis
Created: February 16, 2000
If done properly, converting your Mini to EFI can have many benefits. The EFI Engine Control Unit (ECU) can control all aspects of the combustion of the air/fuel ratio under all conditions. For each and every load point throughout the rev range that the engine may experience, the EFI ECU can calculate the optimum timing and delivery of fuel as well as precisely when ignition will take place by supplying spark at exactly the right time in order to maximise power and torque.
Weber carb information and part no.
Created: January 30, 2000
One of the common problems where sidedraft carbs are involved is the choice of carb size in the first place and choke size in the second. The trick with carb sizing and choke selection is basically one of choosing a size which provides the engine with the airflow it needs without going over the top.
Weber & SU Inlet Manifolds
Created: January 30, 2000
Weber and SU Intake manifolds are explained. Recent development has recently encompassed a detailed look at the manifolds available for side draught carbs. The steel inlet manifolds available have long been acclaimed the very best, out-performing all the alloy types by far.
