My choice is Echo saws.I have two that start easy and run well.My stihl saws started to hard and they come with the PIA filler caps.Here's my dilemma: My Stihl 031 that I bought new in 1978 finally bit the dust after many years of noble service. It was one heck of a rugged saw. So, I'm looking for a replacement and have been perusing websites and a couple of local dealers. What I've found fills me with unease. The current stock seems much less robust - lots of plastic, and I've heard grumbles about poor customer service, specifically regarding Husqvarna. So, what to do?![]()
The 4-mix are valved 4stroke engines running an oil/gas mix so they don't need crankcase oil. This saves weight and they are mostly on the Stihl trimmer line. Some of the newer Sthil chainsaws are strato saws and are still 2stroke. The strato technology allows the saw to take a "gulp" of fresh air between the strokes to better separate the exhaust air from the fueled air. Bad explanation, I know.

Seams like a backwards way of doing things. What's the point of a 4 stroke if you are burning oil? The small Honda engines use crankcase oil but once the engine starts the oil vaporizes so the engine can run at any angle and still get lubricated. My string trimmer has a Honda 35cc 4 stroke engine and runs great. They even use the Hondas in remote control planes that fly upside down.

...they come with the PIA filler caps.
That's good news and about time.The local power company I work for has started to buy different chainsaws because of stihl PIA filler caps.Last month I went to a chainsaw / trimmer safety training meeting put on by a Stihl rep. He said the German guys for Stihl say the only complaints about the locking gas caps come from the U.S. market.
You will be happy to know now on all new Stihl chainsaws there are easy to see alignment marks on the cap and saw to start the cap on right. All other new Stihl equipment in the U.S. Market, trimmers blowers etc. now have standard screw-on caps. No more dumping gas down your leg with a trimmer or down your back with a backpack blower.![]()
stihl is a great saw i have a 029 model and have had zero problems.
I have an MS170 with a 16" bar, an MS311 with a 20" bar, and MS 460 with a 28" bar, and am very pleased with all three. I bought the 311 as an all-around saw, and like it for that, but was getting worn out when it got down to limbing, and bucking smaller trees, so I got the 170. The funny thing is, I find I use the 170 probably three times as much as the 311 now.
I used a Honda powered trimmer a few times. It had great torque. The down side is they have a timing belt that needs replaced like every 100hrs.
The 4mix technology that Stihl uses goes back to the 30's. They used it in Airplanes. Stihl has refined it more.
The timing belt is good for the life of the engine. The Honda uses 100 mL of oil, not much weight savings. Anyway I just thought it odd that Stihl would use a 2 stroke mix in a 4 stroke. Is the exhaust smell the same as a 2 stroke or does the engine burn the oil better and/ or does it have a catalytic converter in the muffler to help clean up the exhaust?
