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.

Tuning your WEBER DCOE-Style Carburetor
Created: February 04, 2011
So you have a nifty Weber DCOE or S&K Racing sidedraft carb setup for your vehicle. You're ready to chew gum and kick butt, and you've run out of gum. You bolted on the carb in place of your SUs or Zenith-Stromberg and voila! You have worse gas mileage, and the power gain is slight enough to be psychological.

Carburetors: Conversion from Injection to Carburetors
Created: April 15, 2005
In the history of the Mini the drive to keep the product alive and marketable meant the factory decided to modernize the fuel system of the Mini from Carb to Fuel Injection. Thus in 1991 the first FI was installed on the Mini. Know as Single Point Injected or SPI for short, the system also incorporated its first ECU into the car. This version of the Mini was produced until late ’97 when it was changed to the Twin Point injected version (also know as a MPI Mini.
SU Carburation - Initial Considerations and Manifolds
Created: March 22, 2001
When trying to improve your Mini’s breathing efficiency, carburation and inlet manifolds are open to as much speculation as other ‘performance enhancing’ components. A great deal of which falls into the b*llsh*t category. As is my wont, I’ll try and outline some basic guidelines.
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.

Austin Mini Cooper - 998 Engine Tunning, Bolt-ons (Stage One))
Created: March 05, 2001
The 998cc engine is a very robust and tunable unit. It is also the most common engine found in standard Minis. Despite the lure of the much-advertised 1380cc alternatives, many simply want to get a little more from what they have at reasonable outlay.
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.

Weber Carburetors Float Level - DGV / DCOE

Last time we chose a manifold based on flow volumes, and a carbie based on personal choice, but which combination is best on this engine?  With the engine finished, it is time to look at a variety of carburettors, inlet manifolds and exhaust extractors, to fnd the most suitable combination. There are a lot of fgures, but they are necessary, so bear with me.
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.
