Hi,
I have a Stihl FS-51 AVE 2-cycle string cutter that was stored for over 1 year without emptying gas. I put in a new plug and cleaned the tank filter which was blocked. The carburator is a Walbro with high and low speed jets as well as an idle adjustment. I took the top and bottom plates off carb and noted there are rubber diaphragms on both ends.
I finally got it running by adusting carb as I read from Hank's instruction on another type cutter. I have used it for a couple of hours. However I had trouble getting the rpm up to optimum speed even after much adjusting of the high speed jet. Also I have a lot of trouble restarting it now. Any help will be appreciated.
