VotW – Joe Curto Discusses Types of SU Carburetors

When it comes to our classic British cars, SU carburetors are one of the common denominators. Sure there are Zenith Strombergs, Amals, and others plus fuel injection, but the SU is the norm. And when it comes to SU carburetor experts, Joe Curto is the man. Joe Curto provides carburetor rebuilding. He also provides a full range of replacement and repair parts. and now, thankfully, he is making much of his knowledge available to us via videos on YouTube. Our video this week is a great introductory one with Joe discussing the different varieties of SU carburetors. After watching this you will not be able to stop yourself from going out to look at your car to make sure of what is bolted up to that manifold. Joe also now offers float bowl koozies. The koozies are used to prevent […]

VotW – Dual S.U. Carburetor Tuning

For our Video of the Week this go round I want to go back to something that gives folks a lot of headaches – tuning a dual S.U. carburetor setup. We are also going back to an old friend for this, John Twist of University Motors. While this video specifically addresses the HIF4 carbs of the MGB, the same basic principals of tuning and balancing apply to all dual SU setups. We covered the basic theory and operation of the S.U. side drafts in the past, but this video is more specific to their actual tuning. [Corrected, see below] By the way, do you know what the “I” in the “HIF” stands for?  It means “integrated”, as in the float bowl is in-line with the carburetor itself, in this case directly under it. If the float bowl is to the side […]

VotW – Side Draft Carburetors and How They Work

Maybe it is the fact that I have been playing with a lot of carburetors recently – both SU and Zenith-Stromberg. Or perhaps it is the fact that I had a friend ask how such a simple design could work. They literally stared at me in dumbfounded amazement when I explained the basic principles by which our carbs work. But, whatever the case, there are a lot of people who consider carburetors a bit of black magic, and I thought this video from Moss might help sort that out. To that end, our Video of the Week (VotW) is “Side Draft Carburetors and How They Work” from Moss Motors. Now in addition to providing a wealth of great parts, Moss also does its part (get it?) to keep our cars on the road by producing a series of videos on […]
