Mowing along quite nicely with my HRZ216 when on a hot day it died. I thought I was out of gas. I should be so lucky. I was half full. Restarted mower. It runs a bout 30 seconds and dies. Okay time to check fuel supply to engine. Blew out the fuel lines and Shut off valve, pulled the carburetor and checked the float and bowl, and blew out the inlet. Fuel starvation is not a problem. Replaced the electronic module. Symptoms remain the same. Runs for 30 seconds and dies. Engine has oil. HELP!!:confused2:
