Trying to use a puller on a Homelite XL12 flywheel so I can remove it . What size bolt is it. I Measure it a 7/32 of a inch. I can not find and bolt long enough of this. What is everyone else using. I tried tap on crankshaft with NO luck. Got to use a puller . I removed the studs and tried 1/4 bolt too big. I am missing something.
