Experienced gardeners share their insights in answering this question :
Is this question about a two cylinder saw ? if so its an oldie but I like em !! seems that two cylinder 2 strokes can develop points issues that fire the coil twice on one cylinder only (sometimes saw will run , with little power) , ck points time, this assumes of course that you’ve got a single coil with two wires exiting it , dual coil saw? id ck the coil that doesn’t fire with a ohm meter

How to Identify and Fix Common Gardening Problems ?

You might get a misfire code after spark plug replacement for an individual cylinder like a P0303. The code indicates a misfire in cylinder three. Sometimes the spark plug is dropped, and the ground electrode and the center electrode can make contact. Or the problem could be with the connection to the coil.
Loss of spark is caused by anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. This includes worn, fouled or damaged spark plugs, bad plug wires or a cracked distributor cap.
If the ignition coil does not have spark, it`s time to check its wires. Use a test light to check the continuity on the signal wire and power wire on the ignition coil. If both wires are functional but the coil fails to produce spark, the ignition coil or the ignition control module is bad.
Repeated overheating of the spark plug tip can cause the plug to prematurely fail. Overheating can be caused by many things like pre-ignition and a malfunctioning cooling system. Pre-ignition can lead to heat building up in the combustion chamber causing the spark plugs to fail.
From the spark plugs to the ignition coils, many different things can cause an engine to misfire. The most common causes of misfires are worn, improperly installed, and mishandled spark plugs, malfunctioning ignition coils, carbon tracking, faulty spark plug wires and vacuum leaks.
When a cylinder misfires, you may experience a proportional loss of power. For example, if one of your four cylinders misfires, you`ll experience a 25 percent loss of power.
Fuel-related misfires can be caused by incorrect atomization of the fuel by the injector. Fuel-related misfires can be caused by bad fuel. In some cases the customer will not bring the vehicle in with an initial problem, but when additional issues occur.
If no spark appears, check for broken wires, shorts, grounds or a defective stop switch. Once you have confirmed that the stop switch is working, reconnect the spark plug lead.
Incorrect timing is the most overlooked and misdiagnosed cause of a no-start. Perhaps you automatically think of ignition timing as the position of the crankshaft when the No. 1 plug fires. While this is important, it isn`t the only timing condition that can influence a no-start.
An engine misfire is when one or more cylinders doesn`t produce power, and there are several possible causes, from a fouled spark plug to a clogged fuel injector or faulty oxygen sensor.
Use a spark plug socket to remove the plug to get a good look at it. The damage you see will help you determine the cause of the misfire. If the spark plug is just old, replacing it may solve the problem. Make sure to replace and properly gap new spark plugs.
Yes, a car will sometimes sputter after a plug change. Spark plugs are manufactured with an anti-corrosion coating on the electrode. After they are installed, they will have a break-in period to clear any fouling which may occur – including the lubricant some mechanics use on the threads.

Misfires don`t simply go away – they need to be addressed immediately. Even if they don`t get worse, they certainly won`t get any better unless you take the car to a mechanic.
Yes. While the damage may seem small initially, the longer you drive with a bad oxygen sensor, the worse the damage will become. Eventually, you may experience rough idling, poor acceleration, engine misfires, an illuminated check engine light, and failed emission tests.
