The picture looks better than my first port attempt at age 17, but that's not saying much. I sure wouldn't want to stand behind work like that.

Definitely not a stupid question, but they do rely on oil mist getting up there. I expect that if you were to put a clear OHV cover on the engine, there would be an astonishing amount of oil reaching the rockers. By the way, Kohler's have a seriously overbuilt valve train. Their valve springs...

Swedish fjord, maybe?

There can't be anything wrong with them. Started out as the perfect computer-designed saw, and has been reworked at least 30 times since release. Actually, I'm sure most work fine, but they've stung me too often to give them much time of day.

We call them 455/460 "Creamy Ranch"

Is there a known power difference percentage between the open and closed port cylinders?

I guess it depends if you are focused on lightweight performance or longevity. To some extent, those are mutually exclusive characteristics.

Don't be concerned about side-to-side play. The piston centers the connecting rod, preventing it from contacting the crank lobes. Usually the only play to be concerned about is up-and-down; make sure that there is no slop when turning the flywheel back and forth. The piston should immediately...

I'm 99.9999% sure he is just trolling.

Great info. The antiquated 8000 filter setup has been an Achille's heel of the saws.

Very cool! I can say from experience that there's an amazing dopamine rush that comes from turning a log into boards. Welcome to the forum!

Yes, it must be a mile different. I just got done milling some hickory and did some ash a few days ago. Those aren't even that hard. Black locust and white oak deserve their own super duper extreme hardwood category.

We have a sign hanging in our shop: A cheap job, quick....won't be good. A cheap job, good....won't be quick. A good job, quick....won't be cheap.

Any piston/cylinder pics? More history?

No experience on the Stihl. I've used the Oppama for years. They come with the weird alligator clip on the end--replace it with a spark plug terminal. They work well; there's no replacement for an adjustable spark stress tester.
