    Certified or not is not so important. Not sure why that is mentioned every were. To me that means he is done the school, not the work and experience. It will likely not run lean for a faulty valve. It will loose compression and if run a length of time it will most often get plugged. Carb fault is can cause of scoring. Not as common as over heating from dull chains and over loading saw, but yes it happens. Usually noticed in performance of saw before this. Scoring on the wall is usually aluminum from piston. As it melts the heat it sticks to the wall. Piston rings can cause scoring if it break up in smaller parts. Mostly they snap in half were it is hottest/softest. Usually right by outlet. I think it ran lean and got over heated. Carb can be faulty or set wrong. Filters can be plugged, all lot of other stuff as well. Fuel is a big factor in this equation.. There is many "tells" you can see when you take them apart to get a feel of what went south. When you put it together you see, feel and hear if its right or not. Performance is the key! If they run right they perform as best.

    I had one saw here that it went thru and made marks in crank. Not common as such stupidity require some effort.

    When I file freehand I can adapt my filing to the users job at hand as well as the model of chain he is using. Each chain model is different, not just in pitch and tooth type. To get them to cut optimally saws engine property's has a big part in it as well. Easy to do when free filing, if you know what to alter to get most out of it.

    They don't function optimally on all chains. Its not a universal thing...

    They set the riders too low for me. I like tooth sharper and riders higher.

    Magnus replied to a thread 020T Gas Tank in Chainsaws!
    The model description when 020 got "updated" was just 020, no T no AV... I have the sales brochure some were. Yes, really confusing. Guy's come in and say they want another 020 and this plastic thing sit on the counter... Many walked away. Those who didn't was mostly positively surprised. Unless they had the accessories for 020AV and wanted a new power unit. Then they were in for an other kind of surprise!

    They are glued/melted together, not bolted as magnesium. One of the 200T variations: 020

    The older magnesium 020 had same tank regardless of handle. There are a few variations but all mix. JB weld and such is harder to get right than changing seal. If its is broken its better to fix each part and put together. Hard to get it to last unless you glue 65% or more of the crack. The newer 020 with plastic tank is another saw completely. They kept 020 name when new model came for some reason but changed it to 200 later.

    If its the older magnesium version its two parts bolted together with a seal. Split it and reseal. I think gasket is still available, but I use "form a gasket" from permatex.

    I file quite a bit. Mostly off saw in a vise placed in chest height. On rare occasion I file on saw, vertically.

    I run only Aspen. If I am not sure the saw has run on it I pull cylinder and clean. Be careful when shifting fuels and especially oils. It can have consequences. About one or two percent of the saws that shift fuels get cooked. Not worth the risk in my opinion. Some oils give carbon buildup. Some oils are penetrating and crawl in under this and it end up burning over piston. If it can't get out right away it burns and is harder and harder. It looks like tiny bits of iron. Sometimes it gets between piston and cylinder. Most get out and rattle around in muffler.

    Could you add this to models library? That would be great. Strips on intakes I see often. Most times its not that good. I have seen a few that works, wide enough with enough pressure in correct places.

    Magnus replied to a thread More air in Chainsaws!
    These are made. Also bigger with up to 600hp diesels. But they are a bit pricey and more complicated to move around. There is a guy that has a portable mill built on his Scania log truck here. He run it with a separate (smaller) scania engine. On log truck he run it from crane. Seen it run on Elmia Wood once. I think point with saws is to use what we have and make the best of it. Running them hot is often more operator error than its a faulty design on saw. They are run too hard so rpm go under the max output and get overloaded at the same time rpm on fan get lowered. Thats were the blower idea comes in I guess. It won't help as saw get damage from overload anyway. It gets hotter faster than heat can travel in cooling fins. Better is to learn how to run it correct.

    If you have 20" or 48" it is same thing. You still need to pay attention and not run it hot. If you do, bar is of little or no importance.

    Magnus replied to a thread More air in Chainsaws!
    Idle on a saw that is too hot is not good as its generating way more heat than airflow around cylinder can remove. That and a low flow of fuel air mix/oil/cooling inside engine will make it get even hotter the first minut of idle. Better is to flip throttle without load a few times. 5-10 depending on heat and size. Don't take my word for it... Get a temp guage and look for yourself. Testing is what I do to find out if something work better than something else.

    When running saws like this its a lot better to not run them hot. Try to make them better with mods in covers etc is not nearly as effective as learning how to not run them hot. If they do, best way to cool them is running without load. just flip throttle up and down in rpm. NO Idle...

    If you open winter shutter it will run on hot air. Not good. There is a reason for having shutter, heat wall air guides etc.

    Many saws have oilers that only work when clutch is engaged. In dry wood and long bars, a couple flips on throttle with bar tilted down a bit usually cool saw as well as lube chain and bar tip. I drill the holes if its tiny just as Brian and always have pumps on max! Oil is cheep compared to bars and chains.

    I tested the 620SX. It ran nice. A good saw for felling medium tree with. Reminded a lot about the HVA162 in performance. Perhaps not the highest chain speed, but good torque and well built saw.

    Not that I am a builder by any means as the guy's mentioned in this thread, but I play with my saws to learn and have fun. I can't let others take my fun.. I need all fun I can get.
