This is really starting to drive me nuts.
After cleaning the carb as thoroughly as I can, including soaking the jet in carb cleaner for a few minutes, then spraying out both ends of every hole with the stuff, and after cleaning the tank with soapy water for an hour, I let the machine sit for a couple of days to let any water dry out.
Today I put more fresh gas in and fired it up. It started right up and ran damn near perfect, for a while.
After a minute or so, the misfire returned. But still the machine was running and running well, just not running perfect.
So I ran down to autozone and got a new spark plug. I threw it in and fired it up.
It has a rough initial start but I feel like that could have just been machine oil on the plug burning off.
So after a minute it was back to running well, with the misfire. I was about ready to call it "good enough", thinking maybe I'm just used to a honda lawnmower engine, maybe this is just as smooth as B&S engines run. . .
Then it started to die. It saved itself, then a few second later, it died. It was like it ran out of gas. But it has tons of gas. I started it back up and it ran rough for a few seconds, then died again.
It sure seems like the carb is clogging up and isn't getting enough fuel. But I had carb cleaner streaming through every tiny hole in that thing. I really don't know what else could possibly be causing this thing to run so bad? The only other part I can replace is the ignition coil, and those aren't too expensive. But it seems more like a furl shortage than an ignition issue.
Also keep in mind the engine was sputtering even with the new carb too (that I later returned).
At this point, I'm at a complete loss. What else could it be? I've replaced or checked everything but the coil, however this doesn't look like a coil problem.
