qualcast classic 35s lawn mower i have fitted the spring to the needle but having difficulty deciding how to fit the spring to the carburettor float ihave looked on the internet and all the floats shown are different to my float where the pin goes on my float there is a gap between the two location holes the floats shown on the internet are one solid piece with no gap i have tried several times but cannot decide how the spring is located in the clip just below the pin
