at least STIHL sticks to the old fashioned flavors

The MS 400.1 runs great. I don´t regret buying.

And I will buy the MS 400.1 with 45 CENTIMETER bar

STIHL 2 stroke vs STIHL 2-Mix engine: ( Link below ) Link

The MS 363 is NOT the manual carb version of the MS 400.1 C-M This is a fact you all should keep in mind MS 400.1 = 2-stroke 2-Mix engine MS 363 = 2-stroke engine ( no 2-Mix ) i.e. you won´t see the MS 363 in regions with higher emission standards like EU, USA, ....

At AGRITECHNICA (The world's leading trade fair for agricultural machinery) we were told , that STIHL will release the MS 400 with heated handles in the nearby future.

By using a sufficently designed manifold (more strato air, less crankcase air) and by decreasing the rev treshold of the strato valve, they can use this engine also for concrete cutters. That is what "simpler" means with respect to the patent claims. i.e. one engine allows many applications

But keep in mind: If a nut is lost, one has to mention, the whole bar might loose it´s tension.

Summary: -injection valve [7] into crankcase -extra solenoid valve [25] to block or choke the strato air: ->no limited coil needed, closing [25] limits the max. rev.

Does the 880 sprocket cover fit on the 881 and vice versa? (They look similar)

:roto2cafe: well, gentlemen. there is always someone , who paid a little bit more. Dsrp 1180$

Okay. If they are looking for s.o. to buy Dolmar. My bid starts with 80$. Cash

Discussed years ago, here or on some other site: The MS 651 has a thicker cylinder gasket. Low fuel quality yields higher probability of misfiring. The thicker gasket reduces the compression and hence the probability of misfiring is lower. That is... if STIHL offers the MS 651 in your country...
