Hi folks, I tried to help a friend with a Toro 520H that won't start. https://photos.app.goo.gl/19fPX79LGMPCBcnB6 (Attempting to insert a photo by URL doesn't seem to be working.) Here are some identifiers for the engine: Engine Model: P220G-I/109556 P/N941811 S/N: A973636148 I went through the usual--checking for spark. I'm getting spark in both cylinders. So, i'm looking at gas. There is a fuel pump on the side of the engine. https://photos.app.goo.gl/RY4hHAfLLGeyCBaS8 I pulled the gas line below it and am getting gas from the tank. I pulled the line above it and cranked the engine. I wasn't getting anything! So, I assumed it was a bad fuel pump. I ordered and installed a new fuel pump, but still no luck. This is a vacuum actuated pump, so I pulled the pump and stuck my thumb over the tube while I cranked the engine. I expected to get either a vacuum or compression. I got neither. Any thoughts about where I go from here? Thanks in advance, Ron
