Here is video of the machine in question. Funny thing is, on video it doesn't really sound like it's doing anything. But in person, its definitely running rough. You can see at the end of the video, how the handle is vibrating.
Ok so the backstory. This is a trash rescue. It was overfilled with oil and wouldn't run. I drained the oil and gas, replaced with the proper amount of oil and fresh gas. It was hard to get it initially started at that point. I had to use a few squirts of starter fluid. But after a minute, it started running under its own fuel and has ran good since. It starts up with one pull every time, even when cold. But it runs very rough after that first pull for 5 to 10 seconds before it starts running better. Better is relative because it still runs a little rough. It feels like maybe its misfiring but it could just as easily be fuel related.
It has a new spark plug and air filter.
So the question is, is this just an issue of a dirty carb, or might there be something worse going on. Like bad compression or bad ignition coil or something like that?
Once I got the machine starting easy and running well, I put 1 oz of seafoam in the tank, then topped it off with fresh gas. I then mowed my whole kinda large lawn with it. I was hoping that would clean out the carb but it doesn't seem to have had any effect. Possibly it just needs to run longer. Also possible its too dirty for that and needs a "real" carb cleaning. Also possible the problem is something else entirely.
What do you think?
As I'm typing this, the video is playing on loop and its so annoying that the audio recording in the video kind of hides the roughness of the idle. One thing you can gleam from the video is that the roughness isn't THAT bad. Its has never stalled on me or anything. Once its running, it stays running. Its just a little rough, it doesn't run like the honda engine on my husqvarna mower.
