Adjusting fuel mixture using Gunson Colortune

The good things about having land Rover Series is you will learn lots of things about basic engine… and purchasing tools or accessories will give us same effect as women buying shoes…

Today I receive Gunson colortune, this  is a tool to help us adjusting or setting  fuel-air mixture from the carburetor, here is the picture…

This is the product… for land rover series you should order the 14mm thread

take one of you sparkplug… and check it see if it is too dark or too brown…

The spark plug seems quite healthy, I wonder whether this Gunson will give me better setting... lest see..

  1. Good work Vidinur :-)

    I had one of those colortunes many years ago before I got into diesel trucks, I have not had a petrol engined Land Rover in 20 years.

      • Is petrol relatively cheap there?

        I think the reason diesel is more popular in the UK is due to the very high fuel prices and the diesels get better fuel economy. Mind you there is not a huge difference in economy between a 2.25 petrol in good condition and a 2.25 diesel in poor condition :-)

        • Yes very true, Landrover was coming to Indonesia when price of petrol is cheap and diesel is not really much of a choice because petrol will have more power… 90% land rover coming to Indonesia is either for military or government purpose… so power is more important rather than fuel economy… Hence diesel is rare here :)
