New Chainsaw prep ?

[bwalker]

Of the last 7 saws I have purchased 4 372's I bought were all to lean as set by the factory, the 361 and 440 stihl were close to spot on and the MS260 was severly lean.
I would never run a saw for long at the factory settings with out verifying them either with a tach, by the sound, or by the cut and feel method.
With differances in altitude and temperature between the various states there is no way a saw with generic tuning parameters is going to be tuned properly in all locales. Depending on how the weather changes in your area the carb my need to be retuned on a semi daily basis.

A buddy of mine just bought a MS280, it was turning 14200 on the tach, Stihl recommends 13500. He used to work at the dealership where he bought the saw, he said they gased them up and sent them out. He said they did not check anything as long as it would run. From now on I will check everything I buy.

does anyone know what kind of parts per million (or whatever units) the difference is in rich and lean? i would suspect pretty small, as 1/8 turn either way off correct setting makes a bunch difference by ear, but i have never seen any figures. just wandering.

John T., just curious, where did you purchase the 385? If you'd rather not say I understand.

Don't know the PPM, but I do know that even a hair change on most H screws can change the WOT 500 rpm. I do wonder what the saw is really pulling a few days after I send it out of the store. I usually set them slightly on the conservative side anyhow, just in case, and sometime VERY conservatively if the customer warrants it...

I think the one thing about running the chainsaw the one thing a person should learn is how to tweak the carb. The humidity, tempature and mix will change the performance. I don't mean just twist the screws a country mile, just tickle them a little. I suppose that is why the factory puts those little idiot caps on the adjusters, afraid they be tweaked too much.
I have never been afraid to purchase a unit on line, but there is always the first time to get a lemon, if a person is afraid of buying on line best be insured with a piece of mind by paying more for assured service.

Wanted to update this thread.... After 17 years my Husky 385XP is still running great.
Only cut 4-5 cord of firewood a year or an occasional "help a friend"
Saw has been flawless, cuts like a beast. every tank of gas I blow it off with compressed air and touch up the chain with a file.
looks like new ... almost..

Carb screws are like chain tensioner screws. They’re there to be adjusted
