Ok, so I have a 50cc kazuma engine. I think it's a meerkat. Since I bought it used, the starter spins clockwise and that's it, doesn't turn the flywheel or sprag. If I spin the engine counterclockwise with a drill it fires right up. If I spin it clockwise it doesnt start up. I've taken off the flywheel looked at the sprag seems to be working fine. I've bought 2 differnt starters for it. Both spin clockwise. I hooked them all up included the old one straight to a battery, all spin clockwise. So my question is, what do I do next to get this thing started with the starter not the drill... Thanks in advance.

 

Depends which way round you "hooked them all up included the old one straight to a battery" as they should be negative earth. I assume the engine is a Honda 50 Cub clone, if so I'm fairly certain they all rotate anti-clockwise viewed from the flywheel side, so all starters will be made for this. Only way I can see them all going the wrong way is for you to have hooked the battery up backwards, this should blow the main fuse, if you have put it on positive earth and the fuse hasn't blown, the rectifier must have blown instead.

 

Thanks for the reply. I can check the fuses. But I took two jumper wires from the battery to the starters and they went clockwise. That's why I'm confused if they do go counterclockwise.

 

Update to thread thanks to merryman. He got my head thinking. So this is what I did. I took off the battery on the atv. Hooked it straight to both of the starters correctly. I got clockwise. .which is the wrong driection. I confirmed it by taking my flywheel off. So I decided to go to my lawnmower and I hooked the starter up correctly...guess what they both spawn counterclockwise. So my question is, how in the world is my battery(battery itself not the wires hooked to it) on my atv backwards. The + is negative and the - is positive. Anyone ever seen this. I've never in my life...lol

 

Never had it myself, but I believe if the battery is allowed to become completely flat, then the charger hooked up the wrong way, pos on neg post neg on pos post, the battery will charge that way round. My point about the fuse still stands, the rectifier is polarity sensitive, so sending power to it the wrong way round should cause it to blow the fuse, as it hasn't I expect the rectifier will have blown.
