This is a straightforward job, but I need help nevertheless. I didn't find anything after searching this site, so I guess it must be easy? I'd rather not buy the $150 flywheel holder called for in the manual, but I don't want to use an impact wrench either cause I'll need to hold the flywheel to properly torque the center bolt (90 ft lbs) when reinstalling it. There are flats on the flywheel center, but they aren't easy to reach, so they don't look like a good place to hold it. Also switching over the starter sprag looks like fun... Any suggestions?
