Does the Tecumseh LAV50 62073C have a compression release?
This engine pulls really hard with the plug in. I took the plug out and it pulls reasonable. I pulled the head to see if it was all carboned up and it wasn't.
Looking at a cam on a parts schematic doesn't show anything and moving the flywheel manually doesn't make the exhaust or intake valve 'bump' at any point in the travel.
This is a points model.
