Rebuilding a Briggs & stratton 12.5 hp model286707 type 042301 off a rear drive snapper. having problem timing the engine the eletric start turnes the er clockwise the pull start turnes the engine clock wise. engine did rune counter clock wise for 20 some years need to know how to time this engine to run counter clockwise.

SOURCE: I'm not sure if the nut comes off turning clock

The flywheel nut should come off counterclockwise. Hold the flywheel with a good pry bar against some solid so as not to damage anything. After that is off the flywheel will be on there real tight. Let me know if you haven't done it before , I can help you there also.

01 Sounds like you are describing the primer as being on the front of the carburetor air filter body. The line you describe is probably used to force air from the primer into the carburetor or into the fuel tank (a box of metal about 6" long by 3" wide by 3" deep?) on which the carburetor body mounts, from your description.
02 The engine will shut down with a little bit of fuel in the bottom of that tank. You should be able to remove the fuel cap, located on the top of the tank, just to the left of the carb and see into the tank. The carb does draw fuel from this tank as it runs.
03 How long does it run before quitting? If it runs ok and you get a small yard done and the engine does not emit black smoke, that might be normal.

Check out this Briggs and Stratton manual and see if it helps you sort things out:

Usually alternator wires are red and black. They also have an AC output that goes to a rectifier to make DC.

This is the standard B&S ignition:

White wires can be for headlights or ignition kill. WHITE / Light wires usually come from the battery positive post.

It is not getting enough fuel. Check the lines, carb, and filter.
