Older BR400 blower problem

[trooper1954]

Yes Fish....Stihl dealer. Thanks bertsmobile1....some good news is it's not neccessary. The shop came through for me and fixed it for free! They said the reason the blower was so hard to pull to start.....the pulling hard caused the key to break.....was that it was flooded and had a vapour lock. It was too late for me to take the plug out as the key had already broken on the first half-pull.
Just thought I'd follow up with the results, and thanks to both of you for the help.

Likely the guy that installed the new flywheel didn't torque the nut down enough, and it ran fine when he tested it and sheared when he shut it down.
