Well, that was the problem. I ran a jumper straight to the battery and it fired right up. It was too hot today to do much so I'll wire it up another time. One problem I noticed is that this motor won't stay running at a low speed. The clutch is supposed to release at 1800rpm and the engine dies before then. I think the idle is supposed to be around 1250rpm for the ohv motors too, which makes it strange. That doesn't really matter though, this one is going back to a manual clutch anyway.
