Gunson G4074 Colortune Single Plug Kit

Great tuning aid.

This is an invaluable aid in carb tuning. Helped me set my idle mixture. After many attempts without the colourtune and no success. I purchased the colourtune just like that its done and the idle is stable and the throtle response is great.Read full review

Gunson G5074

A little disappointed when the package came with the flimsy box and the cleaning brush was missing.
The product works well my Morris minor has never run better.
Would be happy to pay a couple of extra bucks for better packaging

Multi carb tuning

Best and easiest way to get a perfect idle mixture in a multi carb bike or outboard. I tuned my 650 twin bike and my triple carb 90hp Tohatsu outboard. Both are purring beautifully. Love this product. Any anateur could set the perfect idle mixture with this. Read full review

Easy to use big benifits

It is a little known product whose operation is so simple. It makes tuning easy

great tool.

This coloutune was amazing. To be able to see inside the cylinder and see the colour of ignition and tune the carbs to get it right made me feel like a pro. I have already told lots of friends about it.Read full review

Brilliant product

Best investmentment I ever made for setting triple su mixtures. It’s a must have item for the home carby tuner

It suits my need for a sixty year old car

I don’t know if it would be recommended for modern cars that are fuel injected but older carbureted cars that are able to adjust fuel richness are suited to colourtune

Brilliant idea.

Simple and works perfectly. My twin su mgb engine is so much sharper and smoother. Now I know that it is fireing efficiantly.
