2. Rinse the gearbox cavity petrol (100 ml).
3. Pour in new oil (Johnson Gear Lube 80W-90 or analogue) to the level of the control hole.

Fuel system flushing

For two-stroke motors use carburettor (for example, Berryman B-12For E-TEC will require:

1. Disconnect the fuel hose from the engine.
2. Connect the cylinder with compressed air (pressure 2-3 bar).
3. Blow the system for 5-10 minutes.
4. Install a new fuel filter.

3. Checking of spark plugs

Candles should be cleaned or replaced every 100 hours. Johnson:

• 🔥 For two-stroke models: 0.7-0.9 mm.
• 🔥 For E-TEC: 0.5-0.6 mm.

How to check compression in cylinders?

A compressometer will be required to check the compression. Johnson's normal values are 8-12 bar (depending on the model) If the compression is below 6 bar, the piston group repair is required.
