Polaris 350l Trailboss

Hello I put a new flywheel on this ATV as the old one was damaged. Flywheel is identical but I don’t think its going all the way up on shaft. There is about 1/8 inch or less I think it needs to go so the elec starter doesn’t disengage too quickly. Can’t figure it so would appreciate any help. 1992 Polaris 350l trailboss.
