For the soft rubber boots for spark plug wire place a tad of grease in the boot heat the boot in hot water and push the wire and connector in.

Install the boot onto the bare wire, install the spring into the wire, hold the wire while pulling the boot over the spring, job done, easy peasy lemon squeasy.Speaking of the Stihl shop manual... Has anyone had much success installing the plug boot and spring from the plug tower side as shown in the manual? Getting the spring to stay in the wire while bending the whole assembly and shoving it into the boot is an exercise in frustration! I finally found that it was much easier to crimp the spring into the wire and insert it straight into the wire end of the boot using a little silicone spray lube.
