Cosworth Carburettor Mounts - carburetor to manifold

Cosworth Carburettor Mounts - carburetor to manifold

Developed by British-based racing engineers Cosworth, these buffers are specifically designed to be used in conjunction with Misab-plates.

Nowadays produced by that same Misab company from Sweden, the mounts are strong enough to ensure an airtight seal while also providing enough vibration damping.

Each mount consists of two cups and one rubber buffer.

Install the Misab-plates, install your carb(s), install the Cosworth mounts using a Nyloc nut (NOT included in the standard set!) and set the distance between the cups to 2 millimeter, using a normal feeler gauge.
The buffer is now set to the correct tension to dampen vibrations but not allowing air leaks.

These mounts are supplied in sets of 4 complete mounts (as depicted) which is enough for one carburettor like a Dellorto DHLA, Solex ADDHE, Weber DCOM or Weber DCOE.

Note:
Following many requests from our customers, we have sourced superior quality stainless steel locking nuts in size M8 which is the most common size used on carburetor studs.

For your convenience, you can select these from the drop box and order them right along with the buffers but please verify that your studs have that same, M8, thread.

Endless Band Hose Clamp with Buckle - 5 mm wide

Endless Band Hose Clamp with Buckle - 5 mm wide

Endless Band Hose Clamp with Buckle - 5 mm wide.

Again one of those items that allow you to put the finishing touches on a restoration!

This is the famous "endless band hose clamp with buckle" that was used throughout the 1950's, 1960's and 1970's in the car industry.

Unfortunately, these band clamps are only suitable for one-time use and are discarded after removing them.

Over the years, these clamps have become harder and harder to find but we managed to find a source!

We are selling these in sets of 3.

Such a set consist of the following:

  • Approximately 100 cm Zinc-plated band, 5 millimeters wide
  • 3 buckles

This way, you have roughly a foot (or 33 cm) of band per clamp / buckle which is more than enough for regular applications.

Thanks to the generous length of band, there is virtually no limit to the diameter or circumference of the clamp that you wish to apply although these were usually applied to small diameter fuel lines.

Please note that this style of clamping is NOT suitable for stainless steel-braided lines.

Gunson Carbalancer Carburetor Synchronizing Tool

Gunson Carbalancer Carburetor Synchronizing Tool

Gunson Car Balancer.

Internal combustion engines use a mixture of air and petrol to generate their power.

The performance therefore is influenced by the air flowing into it and the petrol that is metered out by the carburettor.

Unless the air flow in Twin or Multiple carburettors is correctly set, the correct mixture adjustment is unlikely to be achieved and this is the simplest tool to achieve that.

Suitable for use on SU, Solex, Auto-Lite (Fomoco), Stromberg, Weber and Zenith and can be adjusted to fit most carburettors including sidedraft, downdraft with air intakes (Venturi) from 25 mm to 67 mm (1”-2”) diameter

  • Easy read scale indicates the air flow and allows adjustment to optimum efficiency
  • Provides smoother and better acceleration
  • Carbalancer can be adjusted to fit most carburettors
  • Easy to follow instructions

The user manual for the Gunson Carbalancer, in English, can be downloaded HERE.

Available from our stock, ready to be shipped.
