Mine did that once. The clutch had came loose and backed off tight against the washer and e-clip. Strangest thing I ever dealt with.Afternoon all,
Might as well start off saying I'm not a Stihl tech and far from one, but I pick things up fairly quickly. I work for a fire department in California and we have A LOT of saws and a few of us are fairly saw savvy despite our lack of professional training. I have access to an SDS and a lot of tools and equipment to basically rival a small, small engine shop, we simply need to knowledge and experience. The InternWeb and YouTube has helped tremendously but i really need confirmation on my thoughts. Now to the challenge! I am trying to fix a MS 261 C-M Z that has less than 8 hours of run time. While it was being ran it began bogging down when the trigger was pulled until it eventually just stopped. Visually everything checks out, nothing obviously broken. When i try to start it on the 'choke' setting it'll pop once per pull for about 3-4 pulls then nothing. after pulling about 5-10 times fuel will start leaking out the exhaust and its plumb flooded. I ran it through the 'check engine sheet' or whatever its called and everything held up like it was supposed to. The station that dropped it off brought by a new black fuel solenoid and i replaced it and the saw fired right up! told then to take the saw and before using it to do a 'reset' of the carb with the 90 seconds idling while on 'choke'. Well...saw was brought back to me and it had been used without being reset and i am back to square one with a saw that wont start and is flooded after 5-10 pulls. I did the test to see if the solenoid was seated properly and it passed, did the leak down test where you pressurize it to .5 bar and count how many pulls to reach 0 and it passed with 7 pulls. I did used the SDS and turned off the solenoid and it held .5 bar will pulling that starter as well. I don't want to just tell the guys they ruined a solenoid and to just get a new one until I'm sure but i wouldn't think a solenoid would go back simply by not resetting that carb. Am I wrong? do they need ANOTHER solenoid and then reset the carb?
