While at Hershey I bought a Holley carb. with the 94 logo and Holley 2100 no. on it. The dis. vacum advance is on the carb. base. What model crs and motors did this fit?? Thanks in advance. Dan
That switch is possible with a throttle shaft change.Lincolns did have it in the base now that you mention it.I have 3 or 4 LZ bases with this vacume port in them.ken ct.
