If the engine won’t crank, you first need to verify if it’s turning over. If the engine won’t even spin, then verify that the battery cables are tight and clean. If they are not clean, use baking soda and a wire brush to clean the posts off. If the cables are good, confirm that the battery is holding a charge. You can have this checked at an auto store unless you have a load tester. Volt meters can mislead you by showing a 12+ volt reading, until the key is turned. Replace the battery if it will not hold a charge. If the battery holds a charge but still dies after starting and stopping a few times, then the alternator could be at fault. A quick test for most alternators is to take a screwdriver and carefully touch the back center of the alternator. If you touch this shaft when the car is running, it will be magnetic and the screwdriver should stick to it very well.
Recoil rope broke on your small engine? Here is a guide to repairing a lawnmower, chainsaw, outboard motor, snowmobile or weed eater recoil. The pull start assembly is usually easy to get to and will not take long to repair. Generally there are up to four screws that will need to be removed for the recoil assembly to come off. Once the housing is off you will see that the rope knot is probably still tied inside the inner housing. To make things easy try to pull the string through the hole of the recoil where it previously or still passes through. pull the rope and count how many times it turns. If you were lucky, that may be how many rotations you will need and won’t have to wind the new rope more turns. When the rope is tight see if you can stick a screwdriver all the way through the recoil slots so it won’t unwind. Slowly release the rope and make sure it won’t unwind. Carefully untie the recoil rope knot located close to center of the recoil and inline with the hole the rope passes through. When replacing the rope only use a rope made for recoils. A new general purpose recoil rope is literally only a few dollars.
What happens when an engine gets flooded? Generally this happens to carbureted cars but could happen to fuel injected cars if there is a problem with it. Every engine needs a specific amount of air and fuel to work correctly. If there is too little fuel the engine is lean if the engine has too much fuel it is rich. Flooding can occur when the ignition system is weak and does not start the engine quickly. If the carburetor (gas petal) is pumped too much before starting the engine can become excessively rich to the point where it can’t ignite the fuel. As you continue to rotate the engine, more fuel is added to the already excessive amount of fuel. There are a few methods to start the vehicle first, just let the vehicle sit, the fuel will evaporate out after 20 or 30 minutes. Remove the spark plug which may be fouled out with black carbon any ways. Slightly fouled plugs can be wiped off, severe cases can be burned off with a propane torch. Severe fouled plugs will need to be replaced, make sure the plug is original and hot enough heat range. After the spark plug is out stick it back in the spark plug wire, lay it on a metal part on the engine, spin the engine and verify the plug is firing. This also helps to get air in the engine and excessive fuel out. The third option is to hold the throttle wide open. In a carbureted vehicle, the air moving through the carb won’t suck fuel when held WOT if the engine is not running. In fuel injected vehicles the ecm, ecu, computer won’t send any fuel through the injectors if the gas petal is held wide open. If the ignition is o.k. and the vehicle floods continuously, then the carburetor idle circuit may be too rich.
