Hello, I am looking for some suggestions on the best practices for dealing with hung leaners such as the one shown in the photos. This one hanging over a hiking trail. The situation is tricky as there is still significant tension/force from the root ball trying to stand the tree back up...

Sorry for another oil thread. There has been some recent discussion on this forum concerning the correct oil for Stihl 4-mix engines. The conventional thoughts are that Stihl Ultra (a JASO-FB oil, now an old formulation) was designed specifically to work in the 4-mix engines and that newer...

Hello, I have a Walbro WT-875 on a small 25cc blower that is driving me nuts! The carb has been rebuilt with an OEM kit. Fuel line has been replaced with Tygon 4040. Fuel filter cleaned and reused. The crankcase up to the carb heat insulator block passes pressure and vacuum (at least when...

Hello, Here is question to ponder on your Sunday evening... What is the proper way to tune 2-stroke engines that are always loaded? For these engines I am thinking mostly blowers or line trimmers. Due to the loading you can't get to the traditional 4-stroking at WOT and can't really judge...

Hello, At least I think that it is chrome. Normally I use red Scotchbrite on Nikasil cylinders which works well to roughen up the bore for new rings. However, red Scotchbrite doesn't touch whatever this cylinder is plated with which makes me think it is hard chrome plated. Suggestions on how...

Hello, I have a small 34mm diameter piston that that I will need to put a new ring on. Are there any good/recommended techniques for doing this to minimize the risk of breaking the ring? For larger pistons I have seen start at the pin and work your way around. Does this technique still hold for...

Search didn't turn up anything so here goes... Does anyone have any good suggestions on how to unstick piston rings? This is assuming that the piston is out of the engine and accessible. Right now I have the combustion chamber soaking in Seafoam just to see if it has any effect on the carbon in...

I have a small cheap Poulan with a CAT muffler. It is crimp sealed so not easy to open and remove the CAT. So what will happen if I richen the mixture enough lower the cylinder temperature for improve longevity? Will the excess fuel now make the CAT run even hotter? Possibly negating the effect...

Hello, I am finding that I need to upgrade my torx drivers. The set I currently have are too short and too fat to fit into cylinder heads and recessed mufflers. Been living too long with the T-27 Stihl "L" wrench! LOL. Today I needed a T-30 to remove a muffler on a Poulan and didn't have it...

Hello, I have two identical Stihl RollomaticE bars. One has a good sprocket but has a seriously worn bar groove. THe other is almost new and I managed to burn up the sprocket to where the chain is into the bar rails (don't ask). So I am wondering if anyone has ever tried to swap these...

Hello, Recently bought a couple of these for our trail club saws. Standard 0.325"-7 for 026/MS260 (0000-642-1236). I about fainted when I heard the price. Not very long ago they were like $5 each. Is my Stihler price gouging? There were 2 other competing dealerships. One downtown closed up...

Hello, Clam shells rely on a small gap to keep the bearing outer races tight and prevent them from rotating in their pockets. I have recently come across a Stihl clam shell that appears to have been manufactured with loose bearing pockets. It is not a saw but a very low hour HS56 hedge trimmer...

Hello, I received two chains like this when a volunteer sawyer retired and turned his saw back in. Anybody see anything wrong here?

Saw is a late 2006 vintage. Engine was completely bone stock. It had signs of running rich as well as the fuel pooling in the intake as is known for this model. I mostly solved the fuel pooling with an "L" adjustment. This worked pretty well but later I noticed that the "L" screw as only 3/4...

Hello, Team Rubicon is a disaster recovery group that has apparently implemented their own sawyer training standards and courses. Have any of you worked with them or have access to their training materials? I am interested to see how their training compares with that of the USFS. So far I...

Hello, Yesterday, I went to our local charity firewood cutting group and found some nice green pecan to cut up. Boy, is that stuff hard! While I managed to get out without hitting any rocks and a still fairly sharp chain the tie straps and sides of the cutters are pretty well coated with baked...

Hello, Working on my first one of these. The oil pump was salvaged from a parts saw with a burnt up motor but looks like it had considerable usage. The pump does flow oil but I was surprised it was only about 1/4 - 1/3 tank of oil to tank of gas. This seems too stingy. It had a razor sharp...

Hello, I have a 2007 vintage Husky 345 E-series (whatever that means) that seems to be pretty stingy with bar oil. Was out cutting a large blowdown 20" dia. so that bar was buried. It looked like it used less than 1/2 tank of oil to about 2/3 tank of gas. It has a brand new 16" Oregon B&C on...

Hello, I help teach a chain saw safety and certification course for our local trail organization. I am looking for an (almost) idiot proof way for a relatively inexperienced user to know if their chain is sharp or dull. What has traditionally been taught in class is to look for good sized wood...

Hello, I just got through rebuilding a Stihl MS251. It has the Zama C1Q-S295 carb on it. It is currently bone stock. I carefully removed the limiter so that I could retune it if needed. In the process I measured that the factory setting for the "H" screw with the limiter full CCW was 1 1/4...
