Hey guys just wondering if someone can help me? I have a 1994 Timberwolf 2x4, I have just put a brand new battery in it and it cranks over when I push the start button but it just isn’t quite enough power to start it? If I hold the start button and help it with the pull cord it starts no worries? And I mean I don’t have to put much effort into it at all to help it start.. could this have anything to do with a stator or a weak starter motor? Cheers guys
