Hello, the following: My Samson no longer takes gas since today. i.e. it starts badly and when it runs then I always have to “play” with the gas so that it remains. At some point it goes out anyway. Stand gas does not take it either. Carburettor is brand new, spark plug is also. I looked at the spark plug in between (the problem already existed): deer brown slightly moist. Tank 1:40 instead of 1:50, since our motor saws also get 1:40 instead of 1:50. At higher speed (half) hears you also always have an irregular “cracking”. Have new oil on the gearbox. AVIA Hydrofluid DLZ. Yes, it wants to sell now, but it would bring much more if it would run. But doesn’t want to put more money in or not over 20€ Because then I could sell it profitably. MFG.
