keep cutting off ?????

When was the last time you did a leak test?

Is it tending to overheat when you fang it?

Could you be suffering from lack of fuel caused by a partially blocked petcock or crap in the needle and seat?
 
ya i did leak down dats ok, i took the petcock off n took the screen off n put inline fuel filter on it now it flows good. could i have a back cdi box or stater?????

If the electrics were poor I would doubt that it would get to 4th gear, but I have been known to be wrong.

How is the float level and have you pulled the carb and cleaned it?
 
sounds like it could be a few things. stators tend to be intemitent like that. possibly a loose spark plug cap or wire somewhere. or a bad coil.
 
Make sure the wires going to coil are connected good if your going to start buying parts I would start with coil since they are cheapest and easiest to replace.
