Who can help me ?
Thanks
Dutch,
PROBLEEM:
Na het loslaten van het gaspedaal bij het schakelen blijft het toerental te lang ‘hangen’, en daalt het toerental veel te traag.
Dit probleem is onstabiel.
Stationair draait de motor zeer mooi rond.
Wat kan dit volgens U zijn ?
Is de opspanveer versleten ? Heeft deze veer voldoende trekkracht ?

Maybe the throttle is sticking?

The throttle pedal is connected by a cable to the engine. Your problem sounds like the cable is sticking.
You can test this by raising the hood (bonnet) and starting the engine. Then, operate the throttle plate by hand. This test will allow you to bypass the cable that is connected to the gas pedal. If the engine responds properly, the speed drops reasonably quickly to proper idle speed, then it confirms that the cable is dirty.
The throttle cable is constructed like the brake cable on a bicycle, there is an outer casing that remains stationary and an inner cable that is connected to the pedal at one end and the throttle plate at the other. Normally, you can use a spray-cleaner that you squirt into the throttle plate end of the cable, and work the cable full travel several times until it operates freely. It is possible that the cable housing is actually broken at one end or the other, so a close inspection would be an important part of your repair effort. The cable housing must be secured at each end. If it is not secure, it can move - and this can cause the cable to stick when you take your foot off the gas pedal.
Good luck, I hope my english is understandable since it is obviously not your first language.
