I have a Honda GX120 4hp locomotive on my lawn aerator that I use. I can get the engine running, but for some reason, whenever I deploy the tines and pull the trigger to make the machine go, it cuts out after four or five seconds. This is on a neck surface. I changed the oil for the first time the day before and I wonder if maybe it is related to it cutting out. There is full gasoline as well. Any thoughts would be accommodating!
Mechanism is trying to run too lean, ( it is not getting enough gas). Could be contamination/water in the carb bowl. cut apart the fastener on the bottom of the bowl and remove it. Watch for water/dirt when lowering the bowl.
If the unit has been sitting for some at all times- goo can accumulate in the small carb or-fices especially if you use ethanol gas.
to handle under normal load. Problem the motor is not developing
enough horsepower to whack the tines because of the bleed off of
compression in the cylinders, Your rings might be bad or the oil
pump is not pumping enough oil to seal cylinder surfaces
airtight so compression is leaking out through the valves or
the oil crankcase.
If the unit has been sitting for some values bright and early- goo can accumulate in the small carb or-fices especially if you use ethanol gas.
