Wonderful Pierburg 1.8 clipper cut out issue

Just bought an '89 1.8 manual clipper and, surprise surprise, I'm having cut out issues. The issue seems to be purely on idle - I drove from Melksham to Bristol and it was fine when I was driving - pulling okay through all gears and sat at 80/90 okay. However, when I dipped the clutch for any more than 3 or 4 seconds, the damn thing cut out. At every roundabout and set of lights I had to keep rolling or restart the thing, which wasn't the easiest.

I was half aware of the issue before purchase and have a spare carb to fit (unfortunately not a Weber…). But, from looking at similar posts, it looks like a good clean of the throttle body will help no-end…

…However - I'm a mechanical novice and couldn't even find the idle control screw earlier (thought I'd run rich/high idle as a temp fix). Can anyone give a newcomer some step by step instructions/diagrams to:

a) locate and clean throttle body (found good one for mk3 golf, but not mk1 clipper)
b) replace pierburg like for like; and
c) replace dreaded pierburg with weber (manual choke???)

Any help/advice would be much appreciated!

Thanks,

Carl

If you decide to replace with a 2nd hand weber, then I can post you the fitting instructions that come with the weber carb.  It?s pretty straight forward (must be, I managed it!).  You just have to bolt it in place, refit the accelerator cable and fit the manual coke into the dash.  I think a lot of people recommend replacing the rubber flange underneath the carb while you?re at it.

Has anyone got a spare Weber going??? If not - just a diagram of how to get me to the throttle body and clean it out and then adjust the idle???

Carl,

I have been through the same as you.  Spent ages taking the Pierburg apart and replacing loads of parts - wax stat, 3 point unit etc.  Never did really get it running properly.  In the end, I went for the Weber 32/34 conversion.  About an hours job to fit and never looked back.  Also, I prefer the manual choke which does not leaving the cold engine revving at 2500 rpm !
