Works on old, forgotten engines.
Would RecommendThis stuff works. I came across an old 2-stroke snowblower that hadn't been used in years and would not start. I put some MIAB in with some fresh gas, primed and pulled a few times to work it through the carburetor, then let it sit overnight. The next day it started, but wouldn't stay running. I left it sit for another day. Then I tried it and it started right up and continues to run. Definitely easier than taking apart and cleaning the carburetor.
