Stihl MS390 versus MS360, Worth Fixing the 390 up?

I would have too look at mine. But I too think you have to pull the whole handle off the saw, which is not an easy task on those. But I do not remember seeing stihl or mahle cast anywhere thats visible on mine either???

 

That is basically what this guy is saying. I looked at some cylinders on ebay and they have Stihl and Mahle cast in them. I'm thinking I may be able to take a screwdriver and feel the "stihl" cast in the cylinder. If not I guess I'll have go by the looks if the cylinder.

Ok after seeing where it is. I am pretty sure there would be no way to see that with the handle on? Maybe I am wrong? But I have never tried to look for mine as I bought it new and its never been at a shop so no way its been swapped. I have had the saw totally apart though..just didnt look for the castings.

 

File half the thickness of the key.
On some builds, the key is removed. It's for location, not to hold the flywheel on. clean and dry surfaces only. Taper fit.
A couple raps with the cordless impact sets it better than anything else I've used.
The factory timing advance is quite mild on the 1127 and 1123 series saws. Levi's 025 has been advanced 10 degrees and still no issues.
That little thing puts out as much power as just about anything else in it's size class. Sans a really hot 346 OE.

 

Gotcha, No worrys.

 

I've got a 250 I've been wanting to play with with. I'll have to keep the 10* in mind. I think the non pro saws are really detuned and there are some big gains to be made easily.

 

I'm thinking more like comparing a round turd to a longer turd.

 

I would be really curious to know what the port timing #'s are in a 250 as opposed to the old edition 025.

 

No i have a better method , i turn the flywheel like a casino rulette when it stop i welded to the crankshaft , perfect every time

 

Why most of peoples believe everything that see to tv ??????

 

dont worry all the china ebay carbs that i have buy writte zama and for ms 180 writte and stihl also sometimes can not understand them , theese shorts make good copies sometimes

 

As the statistics tell not me this F35 is round and long turd together , have loose many times from other older models anyway

 

But as the only super power with a real air force, we are still unmatched. We have spent billions on that project though!!


Thank you to all that wear the uniform, my brother in law included!!

 

You would need to remove the 4 hex screws holding the starter cover and look underneath. If you turn the flywheel so fins are on top you can just see the "Stihl" on the cylinder on mine.

 

Thanks so much, I'm supposed to go tomorrow to look at it. I'll take my battery impact and bits

 

Goverments many times spent millions on bull....... projects , some peoples must eat with golds spoons , for sure not me and you

 

Well, that settles it. Lines have been drawn in the sand. We have the 360 and 440 here to test against it so what the heck! Details to follow!

 

It will probably be a long time before I get into mine that deep.

 

Might have to try advancing the timing.

Here is my 036. I have a feeling the 039 is going to beat it though. Still need to replace the impulse line then she's ready.
