You stated that you were stuffing the carb. I take this to mean you simply removed the air inlet plumbing from the air filter and connected the turbo discharge to the inlet if the carb. As previously mentioned this will not work since the carb fuel bowl is vented and the venturi is now being pressurized. Typically the entire carb is placed in a sealed box and this box is pressrized by the turbo or supercharger. The throttle, choke and fuel lines must be sealed where they enter the pressurized box. As mentioned this is the approach used by Studebaker, Ford and others for the McCulloch/Paxton supercharger equipped models.
Once the carb is placed in a pressurized box it operates the same as when the atmospheric pressure (barometer reading) changes. That is to say the mixture will be richer at low atmospheric pressure and more important it will be lean at high atmospheric pressure. If you keep the bosst pressure to a few Psi you can simply set the mixture on the rich side and live with it being rich when not on boost. If you intent to run higher boost pressures you will need some way of adding more fuel at high boost. The reason this happens is because a carb can not determine the density of the incoming air - the turbo pressurizes the air which increases the density. One final note the fuel pressure must be higher than the maximum boost pressure otherwise fuel will not enter the pressurized box.
Should you decide to add the carb to the inlet of the turbo (suck through) you will need a turbo designed for this application. The turbo oil seals must be designed to operate under an inlet vacuum which of course is not present on diesels.

Today's Featured Article - Grain Threshing in the Early 40's - by Jerry D. Coleman. How many of you can sit there and say that you have plowed with a mule? Well I would say not many, but maybe a few. This story is about the day my Grandfather Brown (true name) decided along with my parents to purchase a new Ford tractor. It wasn't really new except to us. The year was about 1967 and my father found a good used Ford 601 tractor to use on the farm instead of "Bob", our old mule. Now my grandfather had had this mule since the mid 40's and he was getting some age on him. S
