I have a Stihl HT101 pole saw that has probably not been used more than a dozen times. I started it last spring and let it warm up for a couple of minutes but before I could use it it simply cut out. I attempted to restart it but was not successful. I put an aftermarket carburetor on it, redid the whole fuel system and could never get it to run right. I basically went over everything, including pressure testing the crankcase, adjusting the valves, even went so far as to breaking down the engine. I has set all winter and I just put an OEM carb on and it won't start at all. I am totally frustrated. Anyone had any similar experiences?
