The lawn mower is about 15 yrs old and all I've done to the engine up to now is oil and oil/air filter changes mainly because that is about all I know how to do. Recently, It just started to run rough intermittently. It runs fine for a while then starts running as though the choke is out (RPMS drop and spews black smoke) for a few seconds then runs ok again for a little while. I replaced the plugs and that didn't resolve the issue at all so need to know what the next steps would be. I've never been a mechanic by any stretch of the imagination but have recently successfully rebuilt the carb on my rototiller and pretty much a total rebuild on my Stihl chainsaw. So go easy on me with tech talk. Thanks:smile:
Well, it runs great in that it no longer runs rough and no longer spews black smoke. But it doesn't idle down like it used to. RPMS drop a little when I throttle down but still remain quite high. What might I have screwed up during the rebuild?
