I have an MS 180 Stihl and from day one it never really idled properly. I used it infrequently the first year and the warranty period came and went. I would have to keep the throttle depressed a bit or goose it frequently to keep it from stalling and the idle adjustment did nothing. I replaced the fuel line and filter just in case they were bad but no change. I bought an after market carb and put it on and it had the same problem, perhaps worse, and again, the idle adjustment did nothing. I next put on a rebuilt OEM carb and it worked great for a while but now has issues of not getting fuel through after I use up a tank of gas and the saw is hot. It restarts OK after it cools down and sits for a while. So I put back on one of the other carbs because it at least runs and will restart when hot but I can never get it up to full power and it has the idle issue. I assume the quality control on these is bad and there is nothing to be done with a carb that was made out of spec. I have rebuilt all these a number of times with new diaphragms and kits and cleaned the carbs thoroughly but I can tell this is not the problem. I suppose I should buy a new OEM carb and hope for the best. The saw is great when it is running up to snuff. Any suggestions?
