Cleaning and inspection of the carburettor

WARNING!

Fuel has the following hazardous properties:

• The fluid and its vapour are poisonous.

•Can cause skin irritation.

•Is highly inflammable.

Clean all units in clean petrol.

WARNING!

Never direct the compressed air jet towards the body. Air can penetrate into the blood circulation, which means mortal danger.

Use compressed air to dry the petrol on the components. Direct the air through all channels in the carburettor housing and ensure that they are not blocked.

Check the following:

1. That gaskets, pump and control diaphragms are undam- aged.

2. That there is no play on the throttle and choke valve shafts.

3. That the needle valve (P) and its lever (E) are not worn.

4. That the fuel screen is undamaged.

5.That the tips of the high (H) and low (L) speed needles are not damaged.

6. That the intake manifold is undamaged.

Assembly

Maintain a high level of cleanliness when assembling the carburettor. The slightest contamination can result in downtime.

Please refer to the exploded view of the carburettor for letters within brackets that are not shown in the adjacent diagrams.

1.If the throttle and choke valves, shafts, lever arms and springs have been dismantled these must be reassembled. Lubricate the shaft bearings using a light oil.

2.Fit the plug (G) as follows:

A.Place the plug in the hole with the convex side facing upwards.

B.Expand the plug using a mandrel on the top side.

3.Fit the "semi fixed jet" (O) in the carburettor using a man- drel.

4.Fit the fuel screen (N) by using the handle of a small screwdriver.
