Repair instructions
Unscrew the jet needles. Make sure they are clean
and not damaged on the tip of the needle.
NOTE!
Note how the jets are positioned.
(For example, the H-needle is a little shorter
than the L-needle).
Press out the main jet (A) with a suitable punch.
Remove the plug (B).
Carefully drill a small hole (Ø 2 mm) in the plug
and pry it up with a pointed object or use special
tool 531 03 01-91.
Remove the valves and springs. If these compo-
nents are worn, idling is disrupted.
Always replace the valves and springs at the same
time.
