YOur biggest problem will be gasket, seals and then all of junk that will come loose from the fuel system (at least until you get it all cleared out). Then you will have to run it about 40% richer... (theoretically it is about 30%) That is probably not within reach of the adustments... also it will burn much cooler, be harder to start (may need ether) and if you don't get the compression up it may not run very well either... Here is something I found on the web... "
The primary method used to convert non-fuel-injected cars is two-fold. First, any non-compatible rubber parts and gaskets, gas tanks and fuel lines are replaced. Then, it remains necessary to increase the fuel rate of flow by roughly 25% - 30%. This can be accomplished in one of any of several different ways, depending on the specific details of the fueling system. If a car is converted though, the ethanol will clean out the gunk left over from the gasoline and plug the fuel filter. Replace your fuel filter frequently.
For non-fuel-injected engines, this may be accomplished through increasing the diameter of the carburetor running jets to a size that is slightly larger in diameter. The theoretical change is not to increase the hole diameter by 25% to 30%, but rather to increase the area and hence the fuel flow rate by 25%-30%. Hence, the diameter of the jets must be increased by sqrt(1.25) to sqrt(1.30) times their original diameters, while keeping the general shapes at the opening of the jets as close to nearly the same as possible. (The idling jet must also be increased in diameter in addition to the running jet, primarily to accomplish successful starting in colder weather.) An excellent starting point, if one doesn't want to experiment with multiple test trials over the 25% to 30% range, is simply to increase the fuel flow by 27%, which just requires increasing the diameter of the jets by a factor of sqrt(1.27) times the original diameter."
