On Average, a normal 6-8 week old puppy's potty schedule will go something like this: For the first 3 to 4 nights he will wake up every two hours and need to go potty. If he goes to bed at 10:00 pm he will wake up around midnight, 2:00 am, 4:00 am and 6:00 am in the morning. As you are crate training a new puppy for nighttime, don't hesitate, get up and take your puppy outside to go potty.
To provide the extra fuel, a choke is typically used; this is a device that restricts the flow of air at the entrance to the carburetor, before the venturi. With this restriction in place, extra vacuum is developed in the carburetor barrel, which pulls extra fuel through the main metering system to supplement the fuel being pulled from the idle and off-idle circuits.
The choke system is used to start cold engines. Since the fuel in a cold engine is sticking to the cylinder walls due to condensation, the mixture is too lean for the engine to start. The choke system will add fuel to the engine to compensate for the fuel that is stuck to the cylinder walls. Once the engine is warmed up, condensation is not a problem, and the choke is not needed. The air/fuel mixture must be changes to meet the demands of the needs of the engine. The ideal air/fuel ratio is 14.7 grams of air to 1 gram of fuel.
