Hey guys I have an older Montgomery ward snowblower with the 8 hp Briggs and straton engine. It barely runs it runs poorly on full choke and dies almost immediately when I open the choke. When it's on full choke it will idle up really fast then it will just about die then it will pick back up and it will just keep going like that any answers would help thanks in advance.

a carb cleaning is probably needed

It could be the carburetor, try the shortcut I describe here. If the shortcut does not help at all how spunky does the compression feel when you pull the rope? If seems soft try this.

I'd also hose the governor linkage down with something like WD40 to de-gunk it and check for foreign matter nested behind the throttle plate.

Above all I assume you have fresh stabilized fuel in there to begin with.......

I just gave the carb a fresh cleaning I stripped everything down and cleaned it. And the given er linkage moves freely

Then I'd be inclined to look at the valves. You might find sometinng simple like a failed head gasket or even a poorly torqued head on the way in. A good many carburetors get needlessly rebuilt chasing funky compression.

Or a failed coil/weak spark.

The shade tree way, remove spark plug, reinstall wire, rest it away from the hole but against the block, and pull the starter. You should see a strong white/ blue arc, and hear a snap similar to a taser.

The professional technician would use a spark testing tool, that would gauge the strength.
