Make sure the fuel tank cap inlet valve is working properly, this will allow a vapor lock if it is not. Then check the fuel line in tank to make sure the pickup filter is not hung up in tank thereby allowing the fuel to get below the pickup. Also check the fuel line for holes. You can also try toro.com customer care, manuals and parts, type in model no. then get owners manual and see if in troubleshooting section it list this problem.

All magnetos work best with minimal air gap. Gap it with the thinnest piece of paper/plastic that you can remove from the gap. Spin it, examine flywheel for evidence of rubbing. If it's good, start it and zoom it a couple of times, shut it down and check again.
