Carburettor Restoration Process

Step 1 - Assess and discuss

Solex carb as we receive them

The first thing we do is establish what it is, what the likely faults are, if any, and what replacement parts and availability / costs are. We then call you and provide a quote depending on our recommendations and your requirements

Step 2 - Strip down and Photograph

Holley components ready for the ultrasonic tank

Next step is to strip down the carb to its component parts and, as standard, gently clean the individual components in our ultrasonic cleaner. All the channels are then cleared to ensure correct operation.

Step 3 - Vapour blast

We then vapor blast the body components to bring them back to an as new condition, give its a good rinse out then blow through all the channels again.

Step 4 - Plate linkages

An optional part of the service which we'll discuss with you is to plate aluminium or steel external components with a wide range of finishes including Zinc-Nickel alloy in a range of colours, or bright Nickel.

Step 5 - Re-assembly

All the components are then reassembled with a new set of gaskets, diaphragms, jets, floats and valves plus repaired parts. We will let you know if the butterfly bushes are worn and require replacing. 

Step 6 - Final set-up

SU set up and tested

During assembly we set the float levels, set the idle mixture, and idle speed, then test for leaks and problems, so that when you first fit the carburettor to your bike or car it will start first time.

Click the estimate request tab and fill out the form. We'll create a tailored estimate which we'll try hard to hold to. For accuracy, makes, models, years and conditions plus upload photo's all help in understanding the work needed.

Getting them to us.

By far the simplest process for using this service is to post your carburettor to us. The cost of this with parcel force starts at around £11.

If you choose this option, please follow the following steps.

  1. Call, text or email us to let us know what you're sending us, the tracking number and expected arrival date (normally 48hrs)
  2. Pack your carb in a cardboard box with plenty of padding and send it to our address (Coln Engineering,  Unit 3 Alma Terrace, Bristol Road, Gloucester GL1 5PY)
  3. Put in a note in the box with your name, address and phone number plus the model of the car/motorcycle and year of manufacture. We need this to ensure correct jets and set up.

Turn around times.

Standard carburettors take around 4 weeks. This enables us to order and receive repair kits and to complete the work. If the carburettor is rare or needs extensive repair this can take longer to complete the work and or procure spare parts, but we'll let you know as part of the quote.

Payment

You can pay by cash, credit card or bank transfer. We ship once payment is received.


Finally - If you have any questions at all please call, text or email us!
