After reading a post on engine mounts, I checked mine and sure enough , they were sagged enough to allow the carb linkage to hit the frame. Since it was mentioned that this could cause the throttle to stick wide open It was a safety issue so time for new ones. I chose to left the engine with a crane rather than from the sump after loosening all pertinent connections.
Look at the difference. These are the polypropylene ones.
Three hours and some ( more ) character building later the Linkages are well clear now.
