Checked to smell gas in both cylinders only had gas but had spark
Technician: Donald, Small Engine Technician replied 11 months ago

If you are getting spark to the spark plug, and gas is getting to your carburetor, you may have a compression related issue.

Have you checked to see if your valves are opening and closing on the non working cylinder?
