Hyster S40C:
HELP! retrofitted new carburetor on Containtal F163 engine, how to adjust it

Hi there,my old Hyster had old BEAM carburetor but had vacuum leak which they are no longer make it, i found the compatible flange Impco CA125 model and fitted on the intake manifold, connected vacuum line and propane line from regulator, but i couldnt get it running, it had loud pop in the carburetor at first try and i tried again after cranking a bit then another loud pop from carburetor. i think its from the starter fluid flooded in the intake manifold, or its a lean mixture, if anyone can give me a guide how to adjust it thank you!
