Hi ther all can anyone help I want to adjust the choke flap on my pierburg carburetor with out taking it off but can't get to the screw . Is it a flat head or Philips . 1.9 water cooled dg engine automatic petrol .choke flap to big and I have never fone it before cheers colin

The choke flap position is adjusted by turning the autochoke housing.
Three screws on the housing allow flap position to be moved quite significantly

The flap does not close fully and it lies at an angle, giving the impression it's too big

This shows the range of movement

Hi there kev I took the auto choke off and marked it but when I took it off it looked to unravel itself or is that just me seeing things or do I have to re ravel it again cheers colin

Hi kev also which way do you turn for more.choke.on thanks colin I new to.all this thanks for your help mate

anti-clockwise

Does the choke need rewinding after I took it off thanks colin

No, don't mess with it at all. Its a bimetallic spring. It simply tightens up or uncoils slightly, according to temperature. The easiest way to set it correctly is to locate the end of the spring on the choke flap lug and with engine cold (early morning best) turn choke until flap just shuts then tighten screws enough so it doesn't move.

With engine hot, check choke flap is fully open. In normal operation the choke coil will open flap in about one to two minutes.

Cheers covkid you been brill will let you no thankyou colin

thats ok..

Yeah, don't forget Kev. We're both greasemonkeys

Thanks a lot kev you been brill mate so helpful cheers mate I owe you a drink colin

Hi guys tried turning the auto choke when I turn it anticlockwise it opens the flap . So I have turned clockwise . And still no good .It won't tick over on choke unless I keep my foot on accelerater . Any ideas I don't think carb is set up right .

OK
So when the choke is off it ticks over OK?

Yes when it is off it fine it just on the cold start as I can't drive it either from cold it just cuts out

does the choke pull down work?
i.e. does it open the choke flap when you increase the revs?
