Pierberg on DJ 2.1 engine.

[trundletruc]

I have been running my rebuilt 2.1 engine on a Pierberg Carb. I believe that quite a few people have done this with good results. I would like to ask for information concerning jetting and set up etc. Could people who have done this change let me know what they have done?
Mine seems to run okay but seems a bit too rich when the choke is on at start up. Will opening up the choke pull down gap help to cure this?
Is there any specialist engineer near Stafford with a rolling road that could check the set up further up the speed range?

I was sent this link yesterday by Aidan, parts of it may apply to you.

Thanks Tony t25t25 I have downloaded it to add to my other 3 pierburg manuals. It’s amazing that each one has something extra in it that the others haven’t!
