OK - interesting info - perhaps I scip that one then
- anyway one can have a non-branded one locally
quite cheaply ... .
The stihl and husqvarna dont give warranties for the tools sorry. even for the MDG1 or the AUTOTUNE DIAGNOSTIC so buy from ebay or amazon
you happy your wallet happy;);)
 
How sensitive is it with possibly minute leaks in im-
pulse hose?

(One of mine such hoses looks spledid in pinciple,
but possibly as it could have been "shaken" a little
at its fittings due to vibrations to become ever so
slightly untight - just a (hopeful :) ) guess - should
be easily fixable in that case with tie-wraps (if that
is the right glossary) I suppose - which I have
plenty of ... .)

A lot of saws have some common problems , to have a generally idea the saw must hold pressure and vaccum for long time maybe loose a little but its other think to loose 1 psi after 2 minute and other after 5 seconds , some times the temperature and the vibrations deform a little some parts so a just a little leak its not the end of the world, yes you can use tie-wraps but better go to something more oem solution.

Very!
 
So _ I bought a Mityvac MV8500 pressure/vacuum kit
as well as a Mityvac MV5530 compression kit for a total
of 233 USD = 210 EUR from the USA - will have them
here within a couple of weeks or so - Mityvac MV8550
kit has scale pressure/vacuum range +/- 60 psi /4 bar
which seems too hefty for chain saw testing ... Mityvac
MV8500 seems to be the right kit for chain saws with a
scale pressure/vacuum range +/- 30 psi / 2 bar ... .

you only need 7 psi for the tests no more
 
If you look in 346xp workshop manual you are right
that many tests are 0,5 bar = 7 psi - but some are mo-
re pressure - for example that of decomp valve which
is 0.8 bar = 12 psi-ish ... anyway it was no I who start-
ed the talk about Mityvac-stuff :) ... .

before some weeks i have a stihl for repair was full of leaks have leaks even in the handles, the mytivac can not give me a good indication and i deep the saw in water, but i forget to low down the compraised air , i push the triger and ..................... a noise pop listen , its the clutch side seal, go out from the much pressure,
so dont go over 7 or 8 psi
 
OK - thanks - the last thing I want to do is to impose
unnecessary crank-shaft-seal-substitutions on myself
... that's for shure ... .

I dont dip them in water any more I just spray the whole thing with lots of soapy water and look in all the suspected places seals and gaskets being the usual. I test the fuel line, carb, the tank I do vac and pressure vac should not hold pressure should, I check impulse line everything.

i use the soapy water also , sometimes i deep them in water but the most times soapy water
 
now i have a 260 that the rpms dont go over of 10k , tomorow it have a good carb hammer test , it have break my head :angry:
