Gunson G4074 Colortune Single Plug Kit 14mm

Product Information

Failing that, could I use a bit of, say copper brake tubing filled with solder as a link between the adaptor and a standard car male-thread nipple, shown in the picture above? Plug the other end of the adaptor lead into the plug cap of the car's ignition system.The adaptor is designed to fit both types of plug cap (with bare thread or clip type fitting) and fits most ignition systems.Try to keep the leads away from engine parts, particularly the exhaust and rotating items.

Avoid touching ignition parts when the engine is running remember ignition sparks can jump, particularly if a connection is not secure. The principle of operation is not the reason for the warning although I have added a few comments regarding this at the end. As far as I can tell its complete apart from the bottle of cleaning fluid, but the connector to the ignition lead has a threaded end which doesn't, on its own, make a good connection. The information is in two main sections, one covering the various types of carburettor and the second dealing with fuel injection systems.NOTE:A multi-cylinder engine with a carburettor (or injector) to each cylinder and a single exhaust system can not be thoroughly tested with a gas analyser at the tailpipe. The analyser only gives an average fuel mixture indication for all cylinders and no warning of large mixture variations due to setting errors or indication of other faults.

Very simple carburettors found on small motorcycles and garden machinery may have no acceleration device on the carburettor and will need a richer mixture setting at idle to avoid engine stalling or a "flat spot" during rapid acceleration. This applies with a hot or cold engine. If enrichment is by electronic control unit (ECU) or auto-choke, test for a yellow flame when the engine is cool / cold. These are broadly similar to the basic carburettor fuel system described except no adjustment is normally provided for the fuel fed by the main jet system.Early systems use more mechanical parts, later systems still require a mechanical pump to maintain a steady high pressure but control is almost entirely electronic. FILTERS to choose from! With our ever-expanding filter library, you’ll never need another app to find the perfect pairing for your photos. You can even create your own variations for endless creative options, all you need to do is save your favourite filters for use on future edits. Some exceptions to all the above conditions may be found, for example small engines used in lawn mowers or chain saws may have simple fuel systems which are less able to provide the ideal fuel / air mixture. A throttle to open or restrict the main passage of fuel / air mixture to the engine, this usually has an adjustable throttle stop to control idle speed.

COLORTUNE plug-Individually boxed with 10mm, 12mm or 14mm plug size, with reach with 16mm (5/8") hexagonal body size.

It can provide a unique view of the behaviour of the fuel system, in the individual cylinders, which no other equipment can do, saving in many cases time, expense and a great deal of effort in fault diagnosis.

NOTE: Many twin and multiple carburettors require flow balancing before mixture is set - see the end of this section

I originally saw this product advertised in the BMW MOA Owner's News by Bing Agency International (BAI). They claim that this product enables you to "adjust your carburetors precisely". It does so by providing you with what is essentially a spark plug with a transparent insulator. The transparent insulator enables you to see the color of the combustion while carburetor adjustments are made. This is much like adjusting the color of the flame of an oxy-acetylene torch. Some systems attempt to measure flow directly with a moving vane in the air flow, or a hot wire system which senses the cooling effect of the air flow. On systems which have a slow running mixture adjustment, turn the adjustment to explore the range of colour available. Colortune features a viewing window so the air/fuel ratio can be adjusted according to flame colour. Ideal for simple and effective engine tuning. Colortune is available only in a short reach thread length but it may also be used in long reach applications without any problem.
