I would not use Stihl oil at 32:1, it will not burn clean and will build up carbon. I would only use it at 50:1 in engines that are stock.

Don't have an opinion on the company, but AMSOIL Saber (at 40:1) lubricates very well and burns clean. I use it in ALL my 2-cycle stuff. It works well for me, so I use it. Would never claim it is the best, but it is VG. I hear about a lot of different oils, but if this one works well for me...

Well, I like sleepers, so my Mustang's blower is unseen / under the hood. A Whipple Twin Screw Intercooled!

My brother has one, it is stock, and he loves it. My ported 261 is my favorite small saw (with 18" 3/8).

I'm not going to say that temperature does not affect mileage, but I notice a distinct change in my mileage after the fuel changes no matter if it is colder or not. A cold day in the fall compared to a warm day in the winter, when temperature is almost the same, and with the winter fuel my...

I do notice a difference in mileage with winter fuel, usually a decline of 2-3 MGP (or more). I often do the same trip with my F-150 from home to my cabin in the Catskills and back. Half the trip (on Rte 17) is very hilly and results in poorer mileage, especially when hauling the ATV and other...

I run Amsoil Saber at 40:1 in all my 2-cycle stuff. Most of my saws are ported, none are stock. It burns clean, lubricates well and so I will keep using it. Buy it a gallon at a time.

Fuel or oil?

No, I have tried to in the past but it never worked out well, so I don't bother. You can get a good idea of compression when you start them up.

I do not have e-free gas available locally. I run AMSOIL Saber at 40:1 in everything and it seems to stay good for long periods of time and when a builder ripped one of my saws apart, he said the parts were well oiled. It also burns clean. It even seem to prevent the inferior bearings in...

AMSOIL Saber is Blue.

Since we have no way to measure it, there is no way for us to know if you are correct or not. Nice theory though. However, I'll go back to my previous statements: Testing on each saw may be different and is likely the only way to find the best muffler. Most of my muffler testing was done on...

Exactly, that is why headers have collectors, and tubes of the right length and diameter. Conversely, Funny Cars and Rails generally do not have collectors, but they still pay a lot of attention to the length and diameter of the tubes. Similarly on the intake side, a dual port manifold will...

A properly ported saw will usually create power at higher RPMS and will need a less restrictive exhaust ... it is about matching components. Piped saws will create the most power, but they have a "chamber" and smaller outlet, it is all about experimenting to create the correct pulse that...

I will respectfully disagree. I've discussed this with porters who are far more knowledgeable than I am. A hole in the front of the muffler will reduce back pressure (sometimes too much) and result in more noise than performance. They prefer to add openings to the side to preserve some degree...
