There is a great deal of confusion between marjoram and oregano. They are related plants, but are two different species. They also taste similar, although oregano often has a stronger flavor, and both contain high amounts of antioxidants. To make it even more confusing, cretan oregano, O. onites, is also called French or pot marjoram and Greek oregano, O. vulgare, is often called wild marjoram.
Cylinder choke is an unconstricted barrel. The shot pattern spreads quickly. Improved Cylinder choke has a slight constriction. It allows the shot pattern to spread fairly quickly. This is a good choice for quail, rabbits, and other upland game. Modified choke has moderate constriction. The shot stays together longer, making the pattern denser and more useful at longer ranges. This choke is used often for dove hunting and is the preferred choke when using steel shot to hunt for ducks or geese.
2. Clogged carburetor jet holes. If you have a clogged hole (or holes) then the venturi effect in the carburetor cannot pull in enough gas for the engine to have the proper mixture of air to fuel. When ever you keep it on choke there is a butterfly valve that closes restricting the air flow by a little.est Answer: you,ll probably have to take the carburetor off and clean it real good ,chances are the jets are stopped up on it,it could be from old gas also,but either way it has to be cleaned out,then it should run ok,good luck with it.
