Club 80-90 Forums

Hi all,
My pierburg is running rich, ive tried most tings so i thought id just check thats its got the correct jets in as these carbs are used on all sorts of things!
Only problem is i cant find it anywhere on the net.. Does anyone know the jet sizes for a Pierburg 2e3 on a 1.9dg waterboxer on an 1985 t25 5 speed panel van.

Also if i want to check for air leeks whats best to use? wd40.. easy start... lynx africa ??

Thanks!

How have you found out it's running rich?

Brake cleaner... the engine note will rise if it gets in to the engine

I used the Mk1 Nose and colourtune. Cant adjust it out on the carb....

Il have a look for some brake cleaner, thanks!

A gas anyliser test will be a better indicator in my opinion.
It will inform you of the engine state ring and valve wear airleaks (HC), airleaks (O2) and mixture (CO)

I found the colour tune is not very accurate, as it won't take oil burning into account or air leaks causing unburnt fuel making the flame yellow

I'll take a look at the airbleed jet size and tickover jet tomorrow
