I started out with a 334T. I still have it from new from i think 2001? I needs a new fuel line right now as i think i was a little rough when i replaced the primer bulb and something has come loose and fuel streams out when you pump it or start it. Yeah not real safe.
Since then i have had a 338XPT for the last 4+ years and it has been great. Fits me like a glove and i can use it blindfolded i am so used to its feel and handling. I don't know why they get such a bad wrap. I will concede that the bloke that designed these series of saws was smoking something fairly strong to think that the air filter at the front was a winning idea. Other than that nothing, as in nothing, has broken or needed to be replaced other than filters and plugs. Good power to pull the 14" bar in our Aussie hardwoods. It's up there with the most reliable saws i have ever owned.
I use 200T's a lot when i am using my works saws and not my own. Yes power is good and balance and reliability is ok also. They however break down like anything else. I was sick and tired of having to use my own saws because the 200t was in the shop waiting on parts again. Latest repair it got a new carb. Dealer did not ask if we wanted a Chinese carb but we got one anyway at full ridiculous Stihl price. Saw is barely useable now and dealer says it is running the best they can get it to run. It was running better on the old leaky carb. Honestly unless you have the time and patience for the attention these older saws need i would recommend something newer. Boss wanted to run and get the 201T as soon as he could. I said wait a while. This was the original one before they woke up and advanced the timing on the production saws. He still thanks me that i made him listen. I know a local climber that threw one out of a tree cus it was that bad. I have never used one for more than a few cuts however, as i was smart and steered clear from all the bad press. How a company like Stihl can release a saw like that i will never know! When you rely on the saw to put food on your table and all the dealer does is put out his hand for money time and time again and never really get to the root of the problem, it is difficult to establish any trust. The new one Stihl has finally fixed with the advanced ignition timing is by all accounts a close to worthy equal of the 200T. Seems like a nice saw and i would not have a problem with owning one given the chance.
I however followed my own gut feeling and got a T540XP about easter this year. I was a bit concerned about the autotune though and not being able to work on my saws the way i have been used to. Not real happy to plug a saw into a PC! I finally fired it up about 3 weeks ago and am very glad i did! Even on it's first tank, after the autotune breaking in procedure, it was out cutting my old reliable 338XPT in the same log by over 3 seconds.
Same size bar at 14" and both on a new loop of 91VXL. I now have about 6 or so tanks through it and i am leaving my 338XPT at home most jobs. Yes it takes a little longer to warm up and smooth itself out, but i believe that this is just a character trait of the autotune system in general? Power is incredible for a top handle. Even with it being barely broke in it is more snappy and responsive than any stock 200T i have used. I have not experienced the off idle problem i have heard some mention? It seems to cope better being buried in large diameter hardwood too. Feels a little heavier than the 338XPT and maybe a little more rearward bias balance, but i am getting more used to it each time i climb with it. Do not listen to those who say it is a disaster or not built well or some other uneducated nonsense. There are many climbers here (and in the US) who were shelving their useless and expensive original 201T's and buying T540's. Many i have spoke to around our area say they won't be going back to Stihl for a top handle for quite a while because of the complete lack of support regarding the problems with the original 201T.
