Hi!
My E3 2800 currently has a solex 4A1 4-barrel carburetor setup installed by some previous owner.
I’m no carb expert but my plan is to convert back to a dual carburetor setup using Webers. Giving the engine bay a more stock appearance with the original air filter housing in place.
I have started sourcing parts and so far only got the intake manifolds. Got a very good deal on a pair of used weber 38DGES carbs and they are on the way.
Also ordered new air filter housing adapters.
I have seen in 02 forums that it is beneficial or even nessesary to modify the opening in the intake manifolds when installing 38’s.
Does this apply to the m30 manifolds as well?
The 2 holes in the manifolds have different sizes 40 and 36mm.
Will this affect tuning the carburetors in any way? Restrict air flow or making som turbulence?
I have no problem with making the holes the same size or even making one large oval hole if its any point in doing so.
I know there are spacer gaskets available. Will these rectify any issues?
Finally, any suggestions for a starting point regarding jetting?
The Weber seller was unsure of the current setup.
