I just got a ryobi string trimmer for less than a song. It's like new but hasn't run in awhile. The tank was clean and dry but smelled like old premix. I put the 50:1 in it and it runs but not real good I have to feather the choke. I'm assuming the carb or probably the diaphragm has some sludge or varnish in it. I prefer not taking the carb apart as the gaskets and diaphragms are touchy and easy to ruin. What can I ad to the fuel to dilute,remove ,clean it out while running. I would like to try this approach before tearing it apart.
Any suggestions are welcome.
