Dear forum Got a sym. Actually because it doesn’t pull well anymore. However, since this winter it goes off in the stand and after giving gas. On the first time start it jumps immediately stops cleanly the stationary gas for about 15 seconds, then rotates always slower until it runs out. After that it only goes hard. it follows however the same pattern. When I gas-gebe takes the gas cleanly turns without jerking up also remains at speed but if I let it go back on stationary gas again I’ve cleaned the carburetor so far. I checked the fuel supply. I looked at the belt and tried to twist the mixture and the stand gas screw. They react, however, e.g. with more stand gas, this only hesitates out. I normally repair puchs or old tractors of electronics, unfortunately I have little idea. Mfg Lukas
