I use a dry spray lubricant, specifically WD-40 Specialist Silicone at the start and 2-3 times during the season. Being a dry lube, it doesn't attract much dirt or clump. BTW, I typically use dry lube anywhere dust or dirt can be an issue, like bike chains.

So, you're criticizing some for being critical of others. But I shouldn't complain. After all, I'm critical of you for criticizing some for being critical of others. Hopefully, no one will be critical of me for being critical of you for criticizing some for being critical of others.

I'm not familiar with your model but here's basic procedure for adjusting the mixture. I assume you've located the screw at the carburetor. The adjustment either makes the mixture leaner (more air) or richer (more gas). Usually, turning it clockwise will make the mixture leaner and turning...

I agree that lithium-ion batteries like those in mowers can cause a fire, but IMO gasoline is much more likely to ignite and burn. Nearly everyone uses lithium-ion batteries and they're found in almost every home. Products include cellphones, laptops, iPads, toys, flashlights, cameras, and...

Which means what? Common sense dictates there are more fires with gas mowers than battery.

There are many here who post negative comments on battery powered mowers. Most have never touched one.

Battery powered yard equipment can be a good option but costly on an individual basis. My suggestion is to find a battery brand you like and get pieces over time across the brand so you won't need as many batteries: string and hedge trimmer, blower, chainsaw, maybe even a mower. Personally, I...

Agreed. But water in ethanol suspension is dispersed throughout the tank (mostly away from the tank wall) while water not in suspension is concentrated at the bottom wall of the tank. Through the years I've worked on many carburetors but never compared them. I've seen extensive slime and...

There are at least two reasons this is incorrect. First, ethanol dispersing water throughout the tank is a good thing. When spread throughout the entire tank only a small portion of the water comes in contact with the sides. Consider the perimeter of a 12" square is 48" while the area is...

Keep in mind that gasoline is a liquid and air is made up of gases. The gases expand and compress to fill the void as the liquid volume increases or decreases without impact unless the gas is pressurized which, in this case, it is not. There is no one-to-one exchange.

The mower is most likely shutting down because the engine is overworked. I suggest trying the following in this order based on what's easiest: cleaning or replacing the air filter, checking and replacing the spark plug, replacing the fuel filter, cleaning the carburetor, and replacing the belt...

I use either my Big Red hydraulic 2-ton jack or my MoJack 550 hydraulic jack. With the Big Red hydraulic I use jack stands for extra safety.

bertsmobile1, thanks for confirming that fuel tank corrosion today has nothing to do with E10. Note, however, that the move from terne plated fuel tanks is not directly related to legislation and regulation. Rather many car companies moved away from terne (in non-diesel steel gas tanks in...

Spoiler alert: water has been rusting metal parts on machinery since the industrial revolution. Sorry, but water causes rust (i.e., corrosion), not ethanol. And ethanol doesn't create water. The water in the form of liquid or condensation must already be there. Ethanol is hydrophilic...

Here's the reality of all this in a nutshell: The consensus is there is no meaningful detriment (if any) in using high octane fuel in small engines. (Not my opinion but most aren't with me.) No one is suggesting a high octane benefit in small engines. There is a price detriment to high octane...

My understanding is slightly different. Ethanol doesn't create water; it must enter the gas tank at time of purchase or through vents. Ethanol attracts water in the tank which readily attaches to the ethanol. Water in ethanol does inconsequential harm to the engine, no more than water in pure...

Looks like consensus is that 90 (or may be higher) octane gas doesn't harm small engines despite my posts to the contrary. And that's OK. Several noted that the impact of 90 octane gas versus 87 octane is negligible at most so the benefit isn't worth the incremental cost. Beyond that, ethanol...

Why?

Typical BMW compression ratio is 10:1 or higher, while B&S is 6:1.

The issue isn't preignition; it's incomplete or partial combustion. High octane fuels are designed to combust at a much higher compression than small engines produce, on average around double.

For the same reason any business does anything. The fact a business sells something doesn't make it good to use. I go back to what I said before. High octane gasoline is designed to combust at 50% or more above small engine compression psi. That has to mean high octane fuels will not fully...

Skippydiesel, in the interest of space I only quoted a portion of your post. I guess the time difference allowed you to jump in on while we were dosing. I'm sorry you said you didn't agree with me, but your post seems to confirm what I said so I'm hoping you'll switch sides. The issue is...
