The Quoin 2 stroke test kit has been developed as an aid to the engineer.
It has always been the Achilles heel of 2 stroke engines that they rely on the user adding the correct amount of oil to the fuel. Often the user thinks that a few seconds of extra use, with neat fuel, will not cause a problem, but it invariably does!
It is now possible to demonstrate to the customer that sufficient oil was not present in the fuel mixture. This only takes a few moments and can use the small amount of fuel remaining in the carburettor. Most disputes with the customer/hirer can be defused by the intervention of a third party, i.e. the Quoin 2 stroke test kit.
