Save pound’s by having the correct fuel mixture. Tests proved that Colortune can save petrol by enabling you to correctly adjust the fuel mixture at the Carburettor. It actually provides a window into the combustion chamber as the engine runs, so you can adjust the colour of the combustion flame. Pays for itself in petrol savings. ...

Save pound’s by having the correct fuel mixture! Fuel mixture adjustment can be a hit & miss affair. Not with Colortune. This easy-to-use tool temporarily replaces one spark plug at a time providing a window into each individual combustion chamber. Adjust the mixture with the engine running until the correct bunsen blue combustion colour is achieved – job done. Works on carburettor fed & fuel-injected engines. Pays for itself in petrol savings. Its unique design maintains compression while the engine runs & ensures correct firing of the mixture. Gunson G4074 Colortune Single Plug Kit (14mm thread) fits most standard petrol engines. Colortune adaptors are also available. See the How do I adjust the carb on my vehicle ? article in the Technical Articles section ...

Eezibleed kit is an Automatic Hydraulic Brake & Clutch Bleeder Kit. A clever little bleeder that uses the pressure in your spare tyre to bleed air & old fluid from your hydraulic system. Eliminates the need for a helper as you no longer need to pump the pedal. Just connect the Eezibleed as instructed then open each bleed valve in turn until new fluid starts to flow through. Makes a slow messy job quick & easy. Eezi-bleed is supplied with a variety of caps to fit different master cylinders.

The Gunson Gastester is a Digital Exhaust CO Analyser with Pulse Pump. Classics first used after August 1, 1975 get their exhausts probed at Mo T time. If the CO reading is above 4.5 per cent, the vehicle will fail the test (3.5 per cent for cars first used between August 1, 1986
- July 31, 1992). Hook up this Gastester at home & you can check & tune your engine accordingly. Accurate to within half a per cent, the Gastester can save you money on petrol, too. Gunson Digital Gastester may be used on motorcycles & other engines including single cylinder engines.

Gunson G4101 Hi-Gauge Compression Tester is the perfect tool for measuring & recording the pressure created by the piston in each cylinder. Then you can diagnose faults in valves, pistons, worn piston rings, oversize cylinder bores or head gaskets. Gunson Hi-Gauge Compression Tester can also help you to diagnose the cause of excessive oil consumption. By comparing readings across the cylinders, you can determine if the gasket is sound, or if leaking valves or piston rings are at fault. Hi-Gauge Compression Tester has a flexible high pressure hose & fits all 14mm & 18mm spark plug holes. Calibrated in imperial & metric pressure values (BAR & PSI). Complete with trouble shooting guide & instructions. ...
