Briggs & Stratton 30244 Service Adjustments, Engine Speed, Checking/Adjusting Valve Clearance

SERVICE AND

ADJUSTMENTS

Engine Speed

The engine runs at a constant speed.This constant operating speed is maintained by a mechanical, flyweight type, fixed speed governor. DO NOT try to adjust the governed speed for the following reasons.

•Operating the engine at high engine speeds increases the risk of injury and damage to the equipment.

•Operating the engine at low engine speeds with heavy loads may shorten the engine’s life.

CAUTION

Excessively high operating speeds increase risk of injury and damage to generator.

Excessively low speeds impose a heavy load.

•DO NOT tamper with governed speed. Engine supplies correct rated frequency and voltage when running at governed speed.

•DO NOT modify generator in any way.

If the engine is running too fast or too slow, take it to an authorized service center. Changing the engine’s governed speed will void the warranty.

Checking/Adjusting Valve Clearance

After the first 50 hours of operation, you should adjust the valve clearance in the engine.

IMPORTANT: If you feel uncomfortable about doing this procedure or you don’t have the proper tools, please take your generator in to the nearest service center to have the valve clearance adjusted.This is a very important step to insure the longest life for your engine.

To adjust valve clearance:

1.Make sure the engine is at room temperature.

2.Make sure that spark plug wire is removed from spark plug and out of way.

3.Remove breather tube from valve cover.

4.Remove four screws holding valve cover with a #2 or #3 phillips screwdriver.

5.Make sure piston is at Top Dead Center (TDC) of its compression stroke (both valves closed).To get the piston at TDC, pull on recoil handle slowly watching piston through spark plug hole. As you pull on recoil handle, piston should move up and down.The piston is at TDC when it is up as high as it can go.
