Actually Ben the price point & the saws performance is what carried the German saws as far as they got . The limited support killed any real commercial interest . Efco is another example of a decent "Italian saw" both homeowner & commercial grade , that shabby distribution & dealer support killed ! Your absolutely correct , that lack of continuity of field usage within North America , gave little credibility of their actual commercial operating worth !
I always heard about Dolmars being cheap, but not in my neck of the woods. I can't recall exact prices, but they were marginally cheaper than a Stihl and about on par with a Husky. Of course there was only one dealer near me and at the time I lived in logging country.
As for actual performance in the field. The 7900 did cut decent but it wasn't all it was hyped up to be on this sight or what the specs suggested. It was also pretty fragile in a commercial logging environment. That coupled with waiting for parts shipments from Germany soured me on the whole deal and vowed never to by another saw from Dolmar or any other risky dinky mfg. The only real choice is between Husky and Stihl for the professional.
Someone explain how the bad diaphragm carb was pumping more fuel? Wouldn't it be less? OP care to enlighten me?

I read it as the computer was forcing the saw to run rich. Which must mean the computer saw a lean condition.
So how does the carb pump more fuel with a failing diaphragm? Computer dont pump fuel.
Yes, concur, remember that is what the tech saw when he looked a the computer. Computer was trying to add fuel but having a torn membrane it was not getting fuel. Having the carb apart twice a good exam of the guts might have seen the defect.
Update for all the Mad Scientists on here:
at the Dealer today with the 400c
a.) 17 hours on saw
b.) computer is forcing the saw to run rich
c.) Mechanic inspected (as i did twice) C&P = no scoring = shiny like new
d.) His guess = bad carb or air leak
e.) $50 to find out exactly which goes directly to repair
f.) frackin computers are stupid = buy a FREE Carb saw

All it can do is pulse the injector more or less. The computer TRIED to add fuel because it saw a lean condition. It never actually made the saw run rich due to the failed diaphragm.

Wouldn't the computer engage/invole the Solenoid at this point?

i just read this from Stihl website:
"The electronic solenoid valve takes just milliseconds to feed the correct amount of fuel into the engine as calculated by the control unit. Manual carburetor adjustments using adjustment screws are a thing of the past."
That was a question you answered to me meant for the OP because he stated it was in fact .I was trying to tell him it cant actually.
He stated this, see b, he said said forcing not trying to run rich.

No worries.
Well my q
Question still stands then maybe he meant telling it to .

Well, i am sure that the direct quote from the Stihl Mechanic using the word 'forcing' could be easily understood as you now suggest "telling it to".
i seem to remember the Stihl Mechanic saying "the computer is trying to adjust" which would mean it is interacting with the Solenoid, in my estimation.
That is why i looked up the official Stihl website statement which i posted for everyone.
It is important to note that this was my first interaction with a MTronic carb saw.
My normal procedure when cleaning a carb is to have a new carb kit installed as well.
As some of you know, we have cleaned carbs before without installing a new carb kit and the end result was = FIXED IT.
And when just cleaning the carb failed, we installed a new carb kit which fixed-it, as long as the problem itself resided in the carb = failed diaphragm/gaskets/etc.
Thats pretty well what I said in summary within poor distributorship & dealership representation within North America . As for price point every Dolkita I have owned was $300-$500 cheaper than the competition Husquarna or Stihl offered in the same saw class here in the Great White North . Perhaps not the same economic advantage South of the border . Yes , again on the parts sourcing back in the day with the non existent dealer support network . Today over nite parts availability is the norm here . However your obviously correct , none of the German saws ever made a scratch on the North American Commercial Market for the reasons you have indicated . It's been a two horse race pretty much since the early 80's within any serious logging & arborist sector conversation . P.S. Reminds me of the auto sector actually lol. Back in the day I had Camero Z28 & Firebird Trans-Am . 427 & 455 Big blocks . Then finally bought a 1969 Porche & BMW . Day & nite difference in performance & handling & design philosophy's & technology mission statements . Much like what the Japaneese did to the bike market early in the 60's when the British & American big twins ruled the streets . Today unfortunately North American auto industry is a complete joke , Kia & Hyundia rule the small car market & Nissian & Toyota will soon capture the truck market . Pretty sad , sorry for my rant brother !
What saw did you judge the 7900 against because I have a 7900 and it cuts very good compared to anything in its class.
I agree Wolfy , have owned two 7900 & a 7910 . Stock they perform very well within their class . Their AV system is the smoothest I have ever witnessed . However , basic muffler mod or ported they are world class performers and is where they get the name within performance that Ben alludes . I have owned or own ms-660 or 575 xp saws . Some were marginally faster or slower in the cut , stock , however neither handle better or smoother than my Dolkitas . All my 7900 or 7910 eventually became muffler modded (cat delete) or fully woods ported . Then , they became world class performers , that what perhaps Ben experienced in 3rd party water cooler conversations . I know my new 7900 XD ( full wrap & canister air filter with sock prefilter) out of the box was a joke until I removed the cat in the muffler & sock prefilter & retuned with my tach . after a full tank of Shell 91 ultra & 40:1 Red Armor break in . Kevin has agreed to do his renowned porting on it this spring for me that I know will provide a fun filled & reliable performer for some of my 30" plus , White pine blow downs out at camp . lol. Anyhow Ben will fill you in with real world comparison since he has owned more than a few good hardwood saws and is quite right in the rinky dink support they received within the US & Canada unfortunately !
I was mostly running ported 372's and non ported 385's at the time. I did have a stock Ms440 with a dual port muffler as well as a stock muffler modded 372.
I am not saying the 7900 was a turd, it clearly wasn't. It just wasn't overwhelmingly faster than a muffler modded stock 372 and certainly wasn't faster than my ported 372's.
