Cat free sounds good to me. I can't believe they can't leave anything alone. Iam going to try and contact a sponsor. Thanks for all the info.

Makes sense - since the US-spec 6400 is equipped w/ a cat in order to be EPA compliant, I'd imagine the 7300 and 7900 need one as well, but only the 6400 is offered w/ a cat. Perhaps the cat restricts too much flow to be suitable for the larger motors.
If it was just a cat muffler bolt on to get it to comply you would think it would have been done by now. Makes me wonder if still didn't pass with the cat on it and they are working on plan B. (whatever that might be...)

Scott was at our Dolmar distributor today to pick up some oil & saws and he saw a pallet of 7900's that came in today. They still have the stock muffler but they are limited on how many can be imported. But the 7900's have taken another price increase a few weeks ago.

Dolmar has been running the Cat on the 73cc Cut Off saws for a few years now.
I gotta throw a Cat muffler on a 7900. They sound awesome on the PS-6400.
So the question is, are they going to have cats at some point? or are they just going to ship a limited number of saws? Honestly this doesn't look good if you ask me.

Dirty engine is a term invented by EPA and CARB (California air resourses board). The stoichiometry of internal combustion engines suggests that a larger engine will use more fuel and therefore produce more emissions than a smaller one. It is labeled as "Dirty". There are certain displacements that are considered "Clean". It is a system that lacks logic. That is what forced Stihl to produce the MS650. They would rather you run 5 small chainsaws, than 1 big one. At any rate, before you spend your money, call Dave Milliken at 250 282-0001, he is a very nice guy and a sponsor on this site. Even with shipping it might be cheaper to buy a 7900 from him. He is a Dolmar dealer in BC Canada

Potential bad news for 7900 fans.
Called a site sponsor that was recommended to me. Said that he could not ship to me due to his contract with dolmar. Which I undertand
He also said that he cannot get anymore 7900s either. He said he believes that it is going to be even more than a cat muffer but a stratoengine. That just sound like SH!t to me. I hate the epa and ethanol equally.

Makes sense, if a cat muffler alone would have done it, they'd have just used the one from the 6400.

After realizing that I can't get a 7900 down here Iam looking at this.
Bailey's - Makita DCS6421 64cc Chainsaw with 20" Bar & Chain & 84cc Upgrade Option
How close to a 7900 is this. Does it use the same oiler, pull starter, etc? I rebuilt a 660 and a 441 would this saw be about the same to change out the BIG BORE?

The base saw is exactly a 7900 with different colors and a smaller p/c (also the cat muffler). Changing the top end will be no different than doing the top end on a 660 or similar pro saw.

same exact saw except for p&c, colors and decals.
That combo deal is pretty sweet.
The other option would be the same saw from HD for $472 + $180 for an OE 7900 top end.
Do a search, tons of info on the upgrades, pros, cons, install pics, etc. Very popular saw/mod with generally rave review results.

Being that my Dolmar dearlers around here are basically useless, where is a good place online to buy most of the wear parts for a Dolmar. Like carb kits etc. Baileys doesn't seem too. Maybe i just don't know what all the numbers mean on the carb kits. Going to keep reading today to try and inform myself.

The boys from The Cutting Edge above (166 and cuttinscott) or Kyle from Edge and Engine.
They are both excellent dealers and ship parts.
There's a couple of more Dolmar dealers here but can't recall who ATM.
My dealer told me 7900's are still not available and he was told June would be the earliest he would be able to order them. Might be a few heated handled versions available though. No news on whether they will have a cat or not.
Look forward to a revolutionary new 7900 sometime later this year!

IMHO strato engines are a plus, nothing wrong with them at all, and a much better than simply using a cat muffler.
DON'T hold your breath! I remember how long it took for the PS420 and the PS5105 to arrive after word got out about them! From what I hear is the next new DOLMAR will be in the 55-57cc range. Not sure if it will be a new big block design or....................
