Any suggestions would be helpful. Mower died after I started it and got about 50 feet. Took back to shop tested. fuel pump: good fuel is getting to the bowl fuel solenoid working properly. choke closes all the way. cleaned carb put back together and it will still not start. It will start if I spray carb cleaner or gas into the carb opening. But dies when it burns it up. Just want to try everything before I order a new carb.
