A choke removal mechanism for an autochoked engine includes an actuator arm which is configured to have an actuated state and an idle state, an actuator which is configured to be mechanically coupled to the actuator arm, a choke which is configured to have an open state and a closed state, and a choke spring which is configured to be mechanically coupled to the choke and the actuator arm, where the choke spring is configured to mechanically link the actuator arm to the choke such that when the actor arm is in the actuated state the choke is in the open state and when the actuator arm is in the idle state the choke is in the closed state.

A pressure washer may include a pump configured to receive a relatively low pressure fluid inlet and provide a relatively high pressure fluid outlet. The pressure washer may also include an engine coupled with the pump for driving the pump. An electric starter may be engageable with the engine for starting the engine. A flow sensor may be configured to provide a control signal in response to detecting fluid flow through the pump. The pressure washer may also include a controller configured to actuate the electric starter in response to the control signal when the engine is not operating.

Low and medium pressure, high temperature, fluid washers for pressure cleaning surfaces, vessels, piping, tubing, and other structures having a tri-plex pump downstream of a fluid heater in which the high pressure pump employs a barrier seal system with circulating fluid.

A mobile high-pressure cleaning apparatus is provided with a vehicle trailer, on the chassis of which at least two running wheels are held so as to be rotatable, and with a high-pressure cleaning appliance having a motor and a pump, and also with at least one water storage tank for storing water for the high-pressure cleaning appliance. So that water can be provided to the apparatus from the at least one water storage tank or from a water supply mains, without risk of water from the water supply mains being returned thereto, the high-pressure cleaning apparatus has a decoupling tank with at least one inlet which can be connected to the water supply mains, and at least one outlet which is connected to the high-pressure cleaning appliance and to at least one water supply tank via a shut-off member which can be actuated by the user.
