My first post and I am already asking for help.

I have recently purchased a 1972 Westfalia.
Back in 2000 according to the paperwork the engine was changed from 1600 to type 4 1700.
This has had the original awful Solex carbs replaced with a pair of lot simpler Solex 34mm carb kit.
This has also had a 009 distributor allowing it to run without the vacuum advance.
It starts good from cold but when warm you have to give it some gas to fire up.
Also it stutters when pulling away and the smell of fuel outside is quiet strong (no leaks).
I have had the plugs removed and they are all black.
I believe this is a sign that it is overfuelling.
I am thinking checking the ignition timing and balance the carbs would be a good place to start?
I'm trying to find a base setting for these carbs and what jets should be fitted for a 1700?

Thanks

Wrong carburettors, wrong distributor.

The carburettors you now have are wrong.


The original carburettors working properly and set up with their original SVDA for a bus would get rid of 99 % of your issues.

Unfortunately you have been fed prime BS.

start by making sure the chokes are opening properly. Let's start there. If they fail to fully open then the mixture will be terribly rich.

What is your fuel pressure? Too much fuel pressure can cause severe overfueling.

These are the same as Heritage Parts Cantre supply for this engine:-

But the owner has fitted an electric fuel pump as you can hear this tick on switching the ignition on.

Wildthings This maybe causing the overfueling issue?

check to make sure the chokes are opening. If you don't start there you are really wasting your time asking for help. The choke power wires may have come off or broken in which case the chokes will stay closed. That will cause the engine to run right when cold and awful when warm. If the chokes are opening then the engine is jetted too rich.
