Mine only works in the Summer when its warmer, the milometer still ticks over adding the miles, but the speedo needle plays silly buggers, if I need to go on an extended journey I monitor the Satnav speedo on my phone App.

I have a similar problem with my Van, I raised a topic "Pierberg 2E3 Carburettor issues", got a lot of good feedback but still have concerns as It still doesnt feel right. Maybe worth a look at for more pointers.

Ive stuck some smaller wide angled smaller mirrors within the existing ones, not perfect and do drop off if not fixed on with additional adhesive. But the landriver option is good, if available.

The revs seem to have settled to a steady if not higher than idle speed, I have to keep them high, as last time when I thought it had all settled i took it fir a drive and after a short time of driving it appeared ok then later during the drive It kept stalling when coming to a stop at junctions etc...

Thanks te,.it does alter the revs, but constantely needs adjusting it is not loose so does not unwind or wind itself, so suspect something else needs looking at.

Unable to locate items described by Twin Turbo on my Carb, only visible screw is one described in my image to bottom right of image, this alters revs but dont know or what part of Carb it alters or if its the correct one to set idle revs etc.

Thanks again, much appreciated, will try and locate them tomorrow.

Thanks, where is the adjusting screw to make contact with that as guidance keeps referring to. This area amongst others is confusing me

Thanks for reply, the image is of my Carb, when I look at instructions to adjust settings on various guides,, references are made to adjustments, one I have seen on line is to adjust the screw on the throttle lever, mine doesnt appear to have this, so how do i adjust to increase or decrease revs, an...

Cannot seem to identify the above imag as a Pierberg 2e3 as when I look at various images and inforrmation am unable to associate with mine, for example fast idle adjusting screw on throttle lever and adjusting screw to set on second step of cam. Not visible on my carb. So completely baffled.

Annoyingly the problem has returned. Started engine yesterday using cold start procedure, engine ran with a bit of encouragement from the accelerator pedal, revs sounded a bit low for a cold start, after a short period with engine running tapped accelerator pedal engine revs dropped but sounded to l...

Just started engine using cold start procedure, needed a bit of tickling on accelerator to encourage idle speed (couple of taps/depressing pedal for a bit), engine running smoothly at fast idle speed, minute or so later tapped on accelerator and engine revs dropped to normal idle speed. (No rev coun...

Thanks

Stesaw wrote: ↑08 May 2025, 17:16 The cam for the secondary has probably broken which will mean the vaccum will always keep the secondary butterly open thus your revs high. That or your choke is sticking as others have said.

Will look at that also, when i locate it.

thanks, need to locate that item?
