Hi _ I have an 041 AV which I love. The guy I bought it off ran it on about 1:40 with the Stihl 2 stroke oil. He says 1:50 like the weedeaters was too lean. I came across the original factory specs which list it as 1:20 but I think that is when oils weren't as good as today. I tend to go anywhere between 1:30-1:40 depending on my mood. If summer heat I run more oil than in winter. Hope that helps.
I have the owners manual for my 041 farm boss it states " The mix ratio1:40 with stihl oil and 1:25 for other branded oils
67 cc
An 18" or 20" bar would be ideal on a Stihl 041 http://store.chainsawr.com/
The Stihl 041 Super has a 48mm piston diameter and a stroke length of 34mm. Using the formula for the displacement of a cylinder, which is π/4 × (diameter^2) × stroke, the engine displacement calculates to approximately 64.3 cc. This means the Stihl 041 Super has a displacement of around 64 cc.
To start a Stihl 041 AV chainsaw, first ensure the chain brake is engaged and the fuel mixture is prepared. Set the choke to the "cold start" position, pull the starter cord until you hear a pop or see signs of firing. Then set the choke to the "run" position and pull the starter cord again until the engine starts. Once running, disengage the chain brake and allow the saw to warm up.
It stands for Anti-Vibration. I have two Stihl saws made in the 80's (an 015AV and an 034AVSuper). The 034 replaced a really old 041 without the AV, so I can attest that it really makes using the saws a lot more comfortable if you plan on using it for more than an hour or so at once. But then again, all the new Stihl saws have the AV now :o)
The Stihl 041 AV typically uses a 3/8-inch pitch chain with a gauge of 0.050 inches. The specific chain size is often referred to as the Stihl 3/8" PM or similar models, depending on the variation of the chain. It's important to verify the exact specifications in the owner's manual or with a Stihl dealer for the correct replacement chain.
Sthil?? Chinese cr*p; or Stihl?This problem can occur on any type of chainsaw (Husqvarna, Dolmar, Solo etc.) and not only on Stihl.There could be several problems.1) Maybe the clutch is worn out or even broken2) Piston rings might be worn out3) Piston and cylinder might be worn out (these two are very expensive)4) Fuel filter and fuel lines as well as fuel vent (if there is such on your type of chainsaw) might be clogged5) Air filter might be clogged6) Ignition coil might be faulty...I had a similar problem on my Stihl 041 AV. I replaced the clutch (took the good clutch from 031 AV and installed it on 041 AV - it fits and works great, btw :D) and piston rings.
First remove the clutch cover to expose the clutch, bar studs and area of the tensioner. Next you need to remove the bar studs. To do this tighten two nuts agains each other on the bar stud, then put a wrench on the lower nut and use it to loosen the whole stud. Repeat for the 2nd bar stud. Sometimes if you are lucky you can use vice grips on the shoulder of the stud to unscrew them, be careful not to damage the threads. After removing the bar studs, the inner bar plate and tensioner assembly lift right out. http://store.chainsawr.com/
Stihl 041 AV is probably one of the best chainsaws ever made. It has displacement of 61 cm3, cylinder bore 44 mm, piston stroke 40 mm, 4,0 PS@7500 rpm (5,5 PS@7500 rpm reported when tested by DIN), 3,8 Nm@5000 rpm. It weights 7,5 kg with 33 cm bar and chain without liquids (that would be approx. 6,8 kg for powerhead only). Fuel tank capacity is 0,62 l and oil tank 0,25 l. Oil flow rate is adjustable from 4 cm3 to 16 cm3 @6000 rpm.
What are the units of -041 / Are they 'radians ' or 'gradients'. You do not indicate.
There should be a screw that is inside the bar and with the head at the front of the machine. It shares the pin to push the bar with the 041 I own a 031 and it has a different way to adjust the chain/bar. Between the two nuts that hold the bar tight, there is a recessed screw. First loosen the two nuts alittle and then turn the recessed screw - clockwise to tighten. It is something new to me also. I don't know how long Stihl has been using this?
