Solex Carburetter Rebuild

One of our most recent projects is rebuilding a group on Solex Carburetters. Throughout this endeavor we documented the process as well as the final testing.

This is the group of carbutetters before the rebuilding process.


We started with a group of 6 carbs on a flat machined plate. The Base plate is confirmed flat and is used to the test the flatness of the carburetter bodies.


This drill press is used for installation of new bushings.


The original Solex bits are in house machined and fabricated.


Here’s a photo of the bushings being installed and pointed out.



This final photo is a finished throttle body.


Before the carburetors are ready for our customers they are thoroughly tested on one of our vehicles. The video below shows some highlights from this process.

The testing vehicle is a Series 2, 109, 2 and ¼ engine with compression at 165 all 4 cylinders, recent upgraded house built rocker shaft with valves adjusted.  Ignition system is completely OE with a fresh in house rebuilt distributor with a superlative center shaft, fresh points adjusted to a dwell of 40 and timing set at 8 degrees before TDC with a total ignition timing advance of 32 degrees at 2800 RPM.

All carbs are put on this vehicle and tested thoroughly consisting of idle quality testing, cruise, WOT(wide open throttle), torque and overall runability.  Low idle quality is crucial to maintain and uphold the nostalgic running quality of the 2 and ¼. and each carburetor must climb a hill whilst at idle and without any throttle control of 10 degrees incline and be able to acell smoothly out of idling up the incline.

Carburetors available in complete and total rebuilds, new old stock and as used looking but with all jets taken out and cleaned, accelerator fuel pump diaphragm replaced and any worn hardware corrected.

We can build high altitude carburetors and jet them according to your specific feet above sea level.  Over fueled engines are the leading cause of blow by and ring failure.

Owning an early vintage Land Rover for which the parts scene is thinner, requires a sliding scale of mechanical talent and money, where you can substitute one for the other


Carburetor Assesment

Today in the shop we were assessing Solex carburetors for rebuilding. These carburetors are made for Series I, II, and IIa Land Rovers, more specifically the 2.25 litre petrol engine. After completing a rebuild on one of these last week the boss insisted on verifying it was operational by quickly installing it into a 109 series IIa. The mechanic was able to accomplish this, get it out of the vehicle and pass it off to the apprentice to ship with only minutes to spare until the UPS driver arrived.
