Repairs A Little help please

About the plugs.....if they get fouled just spray the electrode with wd40 and clean with a wire brush and they'll work like new

I did say carb cleaner - that works better...:biggrin:

This is a little off topic, but since it was mentioned, I believe WD40 is overused. WD stands for Water Displacement and is great for many things, but it eventually dries and gets sticky. I don't believe it will hurt a spark plug, but there are many things I won't use it for. I had a locksmith tell me he would like to "do bodily harm" to anyone who put WD40 in a lock unless they needed to dry it out and then flushed it out of the lock with a solvent and finished with a good graphite or silicone lock lube. Of course this locksmith was working for the school on salary and did not get big $ for making house calls to free up the locks.

twall, are you on drugs or just f------ with this guy?:laughing: WD40 has NO place on a spark plug! For that matter anywhere on a mower at all...maybe a throttle cable.

So,Your mower that is producing "white smoke", is what I would call unburned fuel & too much oil in it. The simplest answer is usually the right one, Drain your oil....and refill it to the right level. (use 10w30) Change the spark plug(with a NEW one) and replace the air filter!

I said carb cleaner (now for the third time)

Wd-40 works GREAT on spark plugs and just about everywhere on mowers....if u wanna buy a new spark plugs instead of being smart and utilizing the benefits of wd-40 that's ur loss,,,I've had tons of fouled plugs and sprayed them with it and the engines fire up everytime

Carb cleaner dissolves carbon better than WD40.

WD40 is just about useless for anything. The formula was originally developed for the Army for quickly drying out distributor caps in WWII (correct me if I'm wrong). Thus the name.....Water Displacement 40. It used a propellant and a light oil carrier. People, including my dad, swore by the junk once offered to the public (and dropped swiftly by the US Army). It should have never been offered as a commercial product, IMHO. There are better light oils, better penetrating oils, better cleaners, better anything. The Army abandoned it - but because the Army used it for a bit, the public embraced it. It's snake oil, of the mechanical kind - nothing more - nothing less.

Am I clear on my opinon of WD40? Thanks.

My 2 cents on the subject.

What's Inside WD-40?
The Truth Is Out There, and the Nation's Maddest Scientists Are After It
The recipe for this superlube has long been a closely guarded trade secret蓉 until now. Wired sent a can to the lab and got the ingredients.

Mineral Oil
Seriously. WD-40 is mostly a mix of baby oil, Vaseline, and the goop inside homemade lava lamps. "That is NOT GOOD for spark plugs"!!!!!!!:thumbdown: by...CajunCub

Decane
WD-40 contains an abundance of alkanes揺ydrocarbons that match the formula CxH2x+2, usually in a long, zigzagging chain. This one, C10H22, which is also a common ingredient of gasoline, helps WD-40 remain a liquid at cold temperatures. Decane doesn't freeze until around -21 degrees Fahrenheit.

Nonane
Another alkane. One reason these molecules are so handy here: Their hydrogen atoms don't hold a charge, so they can't connect to the hydrogen or oxygen in water, which makes alkanes water-repellent. WD-40, after all, stands for "water displacement, 40th attempt."


Our lab analyzed WD-40 with gas chromatography (GC) and mass spectroscopy (MS). GC separates chemicals based on size, boiling point, and other factors, releasing them one by one over time. MS then blasts the molecules with an electron beam and tells what's what by the mass of the ionized fragments. Tridecane and Undecane
Freeze-resistant? Check. Water- repellent? Check. Contains an alkane that is the major product of the red-banded stinkbug's scent gland? Check! Many alkanes are naturally produced by living creatures. Undecane, part of the pheromone trail left by cockroaches and ants, is present.

Tetradecane
Another alkane! Zzzzzz.

Dimethyl Naphthalene
Here's the thing: This stuff (C12H12) comes in 10 forms, called isomers. One of them is a harmless hormone given off by potatoes. Another is used in high-performance engineering plastics. Our analysis can't determine which ones are present here, but if you're using it as a solvent, as is likely the case with WD-40, they all work just fine.

Cyclohexane
That cyclo prefix means that unlike standard alkanes, which come in chains, this one's a ring. The shape gives cycloalkanes a higher melting point. And huffing them will knock you out cold. (Or so we're told.)

Cajun, you never said 'sorry' for saying I recommended this snake oil.

I will never use it - it's useless compared to carb cleaner, PB Blaster, 3-in-one, Liquid Wrench, and others.....

twall...you changed your avatar, but not you IQ.....:laughing:

 

[twall]

When it won't start, or loses power......hard to say how long. Just keep a spare handy. Sometimes, you can just clean off the oil off the electrodes with carb cleaner.

Let us know if the smoke clears up, ok?

This is my exact quote, dammit. The FIRST stinkin time I said it in post frickin 14!!!!!
