As my pics show the throttle linkage is on the opposite side pf the carburetor...lending that although the carbs may interchange, the linkages do not..... Also to be noted that I blame no one for suggestions or involvement in my posts...we all have a shared common interest and despite the successes and failures of suggestions, I feel intentions are sincere & genuine....My feelings on modifications hinge on the negative side.....A lot of research and testing goes into development, and who am I to change that.....My 70 - 292 has a Rochester and runs perfectly, so its a flaw or imported issue that I'm experiencing with my Rochester B on my 67, not a 'No good' Rochester..... I hope to figure it out........
