Starts fine , idles fine and will walk across the yard to the garden ok, but when I start to till it will rev up and then it will bog down while the tines are in the dirt and die if I don,t let up on the throttle. Takes a few pulls to get it to restart but will bog down and die once the tines are working in the dirt. It's a 4 cycle Mantis on premium gas, proper oil level. Two years old and used about ten times. Fuel line have been cleaned and bulb has fuel in it. Fuel tank clean.
