They will eventually. And most likely sooner than you think. Just like everything else that was once dominated by a 2-Stroke engine market. Especially when you consider that a chainsaw puts as much or more pollutants into the air in 6 hours, that a new car does driving coast to coast. There is no way that ecologically driven states like California will allow for that to continue. The rest of the country will follow suit, as soon as alternative 4-Stroke engines become available. And you can best believe the major chain saw manufacturers are currently working on that full bore as we speak. No matter how you look at it, 2-Stroke engines are a dying breed. It's only a matter of time.... And not much of it remains.

http://forestryforum.com/board/index.php?topic=42187.0

"In one day's use a mid-sized saw puts out about as much pollution as a mid-sized car does driven across the country."

"Anyway, I compared this with a car driven 3000 miles, as shown in the second table, both the Federal regulations and the more advanced ULEV regulations which many cars now meet. As you can see, a saw having the power of a MS-361 and meeting the Phase 1 regulations puts out just about the same total emissions in 6 hours as a car meeting the Fed. Regs. driven 3000 miles."


Meh, I'll believe it when I see it. Can't wait for chainsaws to go up in weight/size while going down in power...

California will do what California always does, but luckily I still live in the freedom loving part of the US smile

Furthermore, the emission differences between an automobile and a hand held power tool mean little. If people start riding chainsaws down the road things may change though... People still plate and ride two stroke dirt bikes on the road, but at least thats more apples-to-apples.

cheers

Nothing new here, been happening for hundreds of years. Only difference is they used to jail you, or saw off some useful limb, or disable some helpful body part, like your tongue or eye. Be thankful for progress.


Time to stock up, then. How long before old chainsaws are selling for twice what they cost new?

Around 2004 I was on a top end run with my 105 mph in the 1/4 mile flat bottom I was cruising at 6500 rpm feeling like I was going fast when a bass boat with a 300 Hp Yamaha and 4 guys drinking beer passed me like I was standing still. After getting over the speed of the bass boat I put the pedal to the metal and even at 7500 RPM limiter I couldn't catchup with the bass boat. Being humiliated I sold the boat . Outboards are so efficient they are screamers on the water.

Some OPE 2 cycle engines use a catalytic converter. Hoping that 50 to one oil is lean enough not to cap the converter with junk. Mostly they work well, now for how long, who knows.

Meanwhile, had a great summer using my 115 HP old school 2 cycle V-4 Yamaha outboard. Thanks for all the posts. Hit it!

Most outboards don't die of engine wear. They die because the lower end gets smashed, the cooling system goes out and they fry, etc.

Around the world, Tohatsu 2-strokes sell well, and will continue to. Once a local wrench learns to tune 2-strokes, they are far simpler to maintain and tinker on than most 4-strokes.

I don't think that 2-strokes will go away in salt water use for a l-o-n-g time. For inland waters that do not she much commercial traffic, sure the 4-strokes will rule. It's just normal market segmentation taking place....

I have had 2 stroke engines on outboards in the past. The 4 strokes are far superior and are the wave of the future until we have electric outboards. I would not buy a used 2 stroke engine because the 4 strokes are so much nicer and quieter. The newer E-tec engines are fairly quiet but can be troublesome and difficult to diagnose. I really like my 2007 Mercury 4 stroke 115 HP which I believe is made by Yamaha. I have had it since 2012 and had zero problems other than the starter clicking instead of engaging once in a while but it would always start. I feared it would drop me dead when I needed it most therefore I replaced the starter.

Last carb 2s I had was a 1996 Johnson ... then a 2006 OptiMax … what a change that was … pretty clean engine and great hole shot …
So now have 2012 4s Yamaha … does not have the same hole shot but love how quiet it runs …
Changing oil is easy …

Nope, the new direct injected 2-strokes (Tohatsu and Evinrude) have computer controlled oiling and lean the oil down to 100:1 for low speed use. They do have over-rides to richen the lube regimen when doing commercial work and during break-in. In some cases they are cleaner than some 4 strokes. They qualify for Tahoe.

I'd love to have a new Tohatsu 90HP 2-stroke. But I'll have to kill the Johnson 70 HP 3-cylinder first; and I have a spare power-head with good compression on all holes, so that ain't likely ...

I also have a 140HP V-4 Evinrude waiting for a short light hull so I can go terrorize the Petaluma River. Not really any enforceable speed limits on San Pablo Bay. That's why the off-shore guys like to test and tune there laugh

4 strokes are the future? Only thanks to marketing. The Etecs are more powerful, burn cleaner, and are more fuel efficient. The only thing going against them is that everybody has it drilled into their heads that 4 strokes are cleaner. The Etec is the cleanest burning outboard made.

Ignorance so many times drives the marketplace. 4 stroke marketers have done a good job.

Don't get me wrong, the 4 stroke outboards are really nice. Just operate one back to back with the equivalent Etec 2 stroke on a similar boat and you'll find a significant difference in acceleration and fuel economy.
