Help Revive a Lawn Mower (and other equipment) that Runs Rough

Judging someone’s character can be boiled down to this key question: do they love going to the dump?

An affirmative answer indicates a visionary – one who sees a fashionably distressed dining set where others see a worn out table and chairs. One who sees the south wall of their new chicken coop where others see dusty old windows. One who sees his new (free) rolling shop stool where others see a ratty office chair.

Why drop $50 on a shop stool when you can get a sweet unit like this free at the dump?

So, while I salivate at adding a lawnmower, snowblower or other piece of equipment from the dump to my family fleet, I also burn with shame toward my fellow man for discarding something that might have been easily repaired.

There has to be a better way

One of the biggest reasons people junk their lawnmower, string trimmer, chainsaw or other equipment is because it starts hard and runs rough. A dirty carburetor is often to blame.

Over time, oxygen deteriorates the gasoline in the carb, leading to the formation of varnish and other deposits that stick the float, block the screens and plug the tiny fuel passages. The result? Fuel that doesn’t flow properly and an arm nearly ripped from its socket from fruitlessly yanking the starter cord.

Engine deposits are another problem

The combustion chamber grows intensely hot during operation. The heat breaks down motor oil, creating carbon that can lodge in the ring lands and cause the piston rings to stick. Stuck rings reduce engine compression, which makes starting more difficult and reduces engine power.

Gasoline byproducts can form deposits on the piston crown, which can lead to pre-ignition. That’s when a super-heated chunk of carbon ignites the fuel/air mixture before the spark plug fires, causing a shock wave in the cylinder that can lead to piston damage.

In two-stroke engines, deposits can block the exhaust port or spark arrestor screen, choking off airflow and leading to rough-running. If bad enough, the engine will quit running altogether.

String trimmer exhaust port plugged with carbon deposits, causing it to run poorly.

An effective way to prevent hard-starting, rough-running equipment is to treat gas with gasoline stabilizer prior to storage and to periodically clean the carburetor and combustion chamber with a good fuel additive. Otherwise, you’ll find yourself at the dump paying to dispose of your lawnmower, snowblower or other equipment while people like me lie in wait, rubbing our hands together with glee.

If your engine and carburetor are already dirty and causing grief, clean them with AMSOIL Power Foam. It’s a potent cleaning agent that…

  • Cleans deposits from ethanol and degraded fuel
  • Removes gum and varnish
  • Maximizes horsepower
  • Restores startability
  • Helps improve fuel economy
  • Reduces pollution

It will not damage seals, gaskets, rubber or plastic materials commonly used in gasoline engines.

I’ve tried it a few times on my lawn and garden equipment, and it’s pretty simple to use. Just run the engine to normal operating temperature, remove the air filter and spray Power Foam into the intake as fast as possible without stalling the engine. You may have to rev the engine to facilitate the process. Make sure you’re in a well-ventilated area because an impressive volume of smoke will emit from the exhaust.

Then, shut off the engine and let it sit for 10-15 minutes.

While you’re waiting, Power Foam‘s potent formula attacks and loosens the built-up carbon and varnish, helping free stuck rings, clean the valves and piston crown, and remove varnish from the carburetor. If the engine is especially dirty, you may want to repeat the process.

Replace the air filter, start the engine and pat yourself on the back for helping prevent the addition of one more perfectly usable piece of equipment to the local dump.

It may be unfortunate for scavengers like me, but it’s great for your wallet.

Why Jay Leno Is Angry About Ethanol In Gasoline

Change is the one constant in life. It’s also difficult, because when there is a change – whether in technology or how we do things – there are often unforeseen consequences.  One of the changes that has been taking place is that since 2005, the U.S. government has mandated that gasoline contain ethanol, most of it derived from corn.  The aim of this policy, among other things, has purportedly been to reduce our nation’s dependence on foreign oil, though it may also be a way to utilize the excess corn of our megafarm corn growers. What this change has done is to set in motion a number of unintended consequences, from its impact on food prices to mechanical issues in our cars and other equipment with engines.

And this latter is what prompted comedian and car collector Jay Leno to write a somewhat impassioned column in Autoweek this month titled, “Can’t We Just Get Rid Of Ethanol?”

Leno argues that this change to ethanol in gasoline has damaging consequences for older cars. The piece begins with a paragraph about the rise in the number of old-car fires lately, stating that the cause is related to the corrosive nature of ethanol when in contact with fuel-pump diaphragms or old rubber hose lines.

Change is a challenge in any field of endeavor, which is why we depend on others to help make us aware of the consequences of change so that worst case scenarios can be avoided. When fuel injectors became the standard in modern engines it was soon learned that deposits on the injector tips needed to be managed. AMSOIL introduced P.i Performance Improver at that time to address this, a much cheaper solution than replacing injectors every time they fouled.

So it is that ethanol in gasoline is now recognized to be a serious issue due to a phenomenon called phase separation. Ethanol is susceptible to water intrusion; when water collects in the gas tank through condensation or other means, the bond between ethanol and gasoline can break because ethanol is hygroscopic (it likes water more than it likes gasoline).

When the ethanol bonds with moisture it sinks to the bottom of the fuel tank, which can create a whole host of problems, including the formation of gums, varnish and other insoluble debris that can plug fuel flow passages and negatively affect engine performance. When this ethanol/water mixture is pulled into the engine, it creates a lean-burn situation that increases combustion chamber temperatures and can lead to engine damage.

Four years ago AMSOIL earned a SEMA New Products award for Quickshot, a gasoline additive developed specifically to address this issue of phase separation. Though initially introduced in a smaller package size for small engines, AMSOIL more recently introduced a quart-sized bottle for automobiles that sitt idle for any length of time.

The more you know, the more you discover how important it is to stay current with the changes occurring all around us, especially when it involves something you’re passionate about like your cars.

How Engine Sludge Forms. And How To Prevent It.

How Engine Sludge Forms. And How To Prevent It.

It’s ugly. It’s sludge.

Sludge.

It’s a disgusting phenomenon. Even the word sounds gross, like the thing it’s describing. The word for this is onomatopoeia, a strange word that many of us learned in high school English class. Splash. Grunt. Whoosh. Swish. Hiss. Frumpy. You know what I’m talking about.

What is sludge?

Sludge is a black gelatinous goo that renders equipment inoperable if not dealt with. And long before the engine’s demise, sludge can foul its sensors and interfere with performance. Some mechanics call it the “black death.”

How does motor oil, which is fluid, become a semi-solid paste or gel inside an engine?

How engine sludge forms

Essentially the formation of engine sludge is the result of a series of chemical reactions. The lubricant itself degrades as it is exposed to oxygen and elevated temperatures. The higher the temperature, the more rapid the rate of degradation. The by-products of this reaction form highly reactive compounds that further degrade the lubricant. Their by-products then react with other contaminants, forming organic acids and high-molecular-weight polymeric products. These products further react, forming the insoluble product known more commonly as sludge. What begins as a thin film of lacquer or varnish deposits on hot or cold metal surfaces eventually bakes into an expensive mess.

Synthetic base oils help prevent sludge

Fortunately, sludge and varnish deposits are something we oil manufacturers have a measure of control over. Using thermally stable base oils reduces the rate of initial degradation (oxidation). A good example of this is the use of common synthetic base oils such as API Group III, PAOs and Esters. Anti-oxidant additives help reduce the rate of degradation as well. One of the most widely used is zinc dithiophosphate. Not only is it an excellent oxidation inhibitor, it is an outstanding anti-wear additive as well.

So do high-quality additives

We can further address many of the issues occurring after the initial oxidation stage. Additive chemistry such as detergents and dispersants are commonly part of motor oil formulation. They help promote the suspension of contaminants within the oil and keep them from agglomerating. Detergents, which are also alkaline in nature, assist in neutralizing acids that are generated in the sludge-building process. Anti-oxidant, dispersant and detergent additives are consumed during use. To achieve maximum life expectancy, use an oil with high concentrations of these additives.

Severe service invites sludge

Good lubricants minimize sludge and varnish issues. How the equipment is used also has a bearing on the likelihood of sludge or varnish issues.

Stop-and-go driving, frequent/long-term idling and operation in excessively hot or cold weather can all increase the likelihood of sludge and varnish, especially if using more volatile conventional oils.

Interestingly, most auto manufactures note in their owner’s manual that operation under any of the above conditions is considered severe service and requires more frequent oil changes. From a mechanical standpoint, things like adding too much oil to the oil sump, antifreeze contamination, excessive soot loading, excessive oil foaming, poor engine combustion efficiency, excessive blow-by and emission-control-system issues can all lead to the formation of sludge and varnish.

By practicing good maintenance and using properly formulated, premium synthetic lubricants, like AMSOIL synthetic motor oil, your vehicle won’t succumb to the “black death.”
