Wat nu! Ik adviseer de bekende VW-voet-dwars techniek :p

Keertje afstellen lijkt me...

# Engine warmed up, but switched off. The screw on the throttle arm, which faces to the rear of the car is called the Fast Idle Adjuster. This works with the choke to give a smooth idle on a cold engine. Unscrew the Fast Idle Adjuster (sits on the stepped cam), until it is clear of the stepped cam. Now screw it in until it JUST touches the very bottom of the stepped cam - NOT on any of the steps themselves. Now screw it in another 1/4 turn - no more. This sets the throttle butterfly open the required .004 inch, so you can use the Bypass screw (read on) to set the idle speed correctly. Now leave the Fast Idle Adjuster screw alone.

# Turn the Volume Control Screw (smaller screw in the side of the carby) in until it bottoms. GENTLY please - you don't want to open up the hole. Now unscrew it 2.5 turns. This is the starting setting.

# Start the engine and use the Bypass Screw (larger screw in the side of the carby) to set the idle at 850rpm (fast idle if you don't have a tacho). For a semi-auto car, use 900rpm.

# Go back to the Volume Screw and adjust it slowly for the fastest idle. It should not be much outside the range of 2-3 turns (½ turn in/out from the 2.5 basic setting). Then turn it very slowly IN until the revs drop by about 30rpm. If you don't have a tacho, listen until you can just hear the revs start to drop, maybe as little as 1/8th turn.

# Now use the Bypass screw again to reset the idle speed to 850 rpm (900 for the semi-autos).
