this video's may help you with you're problem. \/
Also for pulling the bearing out of the axle I recommend a bearing puller set you can buy cheep online and rent a slide hammer from most auto shop's another video about the tool. \/
and use a socket that has the same outer diameter as the bearing to install.
If the rear axle is not the same please disregard this
but the video may still give you some insight as of whats ahead.

good luck..

Your alternator/regulator/rectifier is blown or a bad connection within these components

Possible vacuum or intake leak

Is the cooling fan not working? if it is I would check for any restrictions (mud, leaves etc)

Faulty starter solenoid or relay possibly

Had a similar problem, I rebuilt the carb and fixed any gaps/cracks in the intake boots and carb-engine gasket. runs ok now
