Have a couple husqvarna 122c trimmers i thought would be an easy fix but so far it has been anything but. I believe it's all down to these crappy RUIXING carbs. Cold start and running is bad they vibrate and knock and dont rev well, once warmed up they run ok however 5mins into use it begins to lean out, will just die if you squeeze the throttle quickly, adjusting the mixtures helps but doesnt fix it. there's still plenty of fuel in the tank but it just won't pick it up. stop and add a bit more fuel it goes ok for a bit longer. ive tried endless adjustments, carb cleans, checked the tank breather is ok, fuel filter is ok. sometimes it'll start 2nd pull othertimes it's over 10pulls. sometimes it'll run great othertimes crap i just cant get my head around it. also cant get over how much difference the air filter and cover make, pull them out it literally wont start or run. as it is the high speed mixture screw it almost completely closed. does this sound normal? has anyone had a any success getting these things to run properly, consistently?
thanks
