Gunson G4074 Colortune Single Plug Kit 14mm

Product Information

When the engine is running slowly at idle and there is a sudden demand for power (throttle rapidly opened) this can cause an unstable condition and the engine may stall. When there is too much air in the mixture, it becomes more difficult to ignite, burns slower, and is therefore less efficient. These products has a smaller internal volume which maintains the normal compression ratio and a higher heat range, more suited to high perform. ance engines. Avoid touching ignition parts when the engine is running remember ignition sparks can jump, particularly if a connection is not secure. 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.

The other type of nipple is often used on motorcycles here. This type has a "female" threaded hole in the base which accepts the "male" threaded rod that is in the top of the complementary type of spark plug. I THINK these spark plugs are often supplied without the nipple, but I've only bought one once, so this practice probably isn't "universal" either. A rich and easily ignitable mixture helps to avoid this, so it is common to see a yellow combustion flame with rapid engine acceleration. Hydrogen in the fuel burns with the oxygen in the air to produce water (H20) • Nitrogen in the air passes through to the exhaust with little reaction.There are sometimes exceptions to the above as petrol engines are imperfect machines, these will be described later. A twin choke (progressive) carburettor where one choke is used for most low speed driving and the other opens in addition for high speeds. This gives improved economy and smooth engine response The carbon in the fuel burns with oxygen in the air to produce carbon monoxide (CO), which then burns with more oxygen to produce carbon dioxide (CO2)

The lighter blue is due to a slightly leaner mixture (less fuel) arranged to give improved economy at part throttle operation. Now we're getting somewhere. Your picture is worth a thousand words -- as they say -- and I see that you don't have to use the mirror Any idea what the little brass washer is for? Extension H.T. lead incorporating an end suitable to connect either Champion or Continental Bosch type suppressor caps (clip or thread) Sorry, the instructions you kindly provided are not much clearer than the ones that came with the Colortune... and I don't think I want to be looking at a sparkplug while someone is gunning the car in third gear with the brake on!A thread size of 14 mm is almost universally used as there are no space restrictions caused by valves. I know all this, the reason i put my post up is because of the majority of numb nuts on here at the moment, they get a little bit of knowledge and think they can answer every question! Note: At idle the same lean economical setting is difficult to achieve due to engine inefficiencies at slow speed with the throttle virtually closed. A high speed fuel feed and adjustment (main jet and main mixture screw) normally located closer to the inlet air cleaner mounting flange.The main fuel discharge feeds into a venturi shape, whose restriction (a fixed size choke) gives a low pressure to pull the fuel in.
