I don't have a lawn mower or anything, I live in an apartment complex haha I will have to figure something out, maybe a bucket or something I can seal and then slowly mix it in with new good gas until its used up.
I just took it out in the parking lot and ran it around some. It still have times where it wants to hesitate/lose power, and if I hit the clutch and rev it up some, then its fine. I was able to get enough of a run up to get a good high rev in first and shift into second, but there isn't space for much more here at my workplace
