COLOURTUNE SERVICE KIT

Ingenius kit which allows you to see the colour of the combustion in the cylinder head chamber by virtue of a glass topped spark plug.This takes the guess work out of mixture adjustment as different fuel/air mixtures burn with different colours. A full chart and instructions make this an easy to use kit. One of the few kits that earns its cost back by saving fuel and money in a short time with the fuel cost in the UK.
