While all my gear is ICE, there are rules to using lithium batteries for long life, the main one being not to run them right down continuously......been a lawn contractor for over 30 yrs, if l was starting over l'd be looking at all battery gear, KRESS perhaps?
My trusty old blower has had a dizzy fit and broken the recoil spring in the starter.......wondering if anyone would have one they'd be willing to sell me. They are discontinued and unavailable. l've since bought a new blower but would love to have this as a backup.
l ordered one from Jacks...
Not sure if l should post a link to another forum (delete if not allowed) but this explains it perfectly, and is where l did mine from https://www.mytractorforum.com/threads/starter-assist-relay-assembly-and-install.209618/
