FOUND IT Any dolmar dealers still have a blue 7910?

[fordf150]

What do they run with the HD filter and full wrap handle bar?

EA7900PRZ2 is what your looking for

 

[exSW]

Buy one!

Really don't need another 80cc.

 

[SOS Ridgerider]

I didn't need another one either, but by the time I'm done with these two, I'll have four of them. I clearly have a problem with the Dolmars and Makitas, but I'm completely ok with that. Lol
I really like these saws, and my first Home Depot Makita was the reason I sold my Stihls and Huskys.

Two saws I'll never sell. My dolkita 6421 and my Poulan 4200. Everything else has its price.

How do they run never ran one? Is the 7900 or 7910 as good as an 044? Guess i need to start looking for one

 

[astnmacgto]

I ran one of them the other day to cut abut 6 cookies, Ive been told they were a very smooth running saw, well that is an understatement. Vibes were non existent and it cut so smooth it is like it wasn't even running. Whatever the dolmar engineers did, theyve got it figured out

Just wait till you put that 7900 top end on it and bury a 28" bar. It makes me smile every time. Run a 5 series husky. They are the same way, very smooth.

A 7900/7910 will at least hang with an 046 size saw.
Check the Home Depot used rentals. I've gotten at least 3 that way, and I believe that's where @astnmacgto got his two from as well. They're good and torquey saws at 64cc, but once you get a 79cc top end on them they're fantastic, in my opinion. Some of the smoothest saws I've ran too.

Whats the diff in 7900 and 7910

 

[SOS Ridgerider]

Whats the diff in 7900 and 7910

7900 is the original, 7910 is the newer version. There are a few differences. The 7900 has a higher limited coil, 13,500 vs 12,800, non EPA muffler, and the cylinder and piston are slightly different. You can only buy 7910 top ends now.
The Home Depot saws are Makita 6421 with 13,500 coils, and stainless mufflers. Makes a great saw to convert to 79cc. I believe at least one of the builders here on the site prefers doing the 79cc saws this way to get the higher limited coil.
The flywheels are different too, and need to be matched with the proper coil, although I know som have used a 272 coil and made these saws unlimited.
There might be other differences, but these are the ones that come to mind at the moment. Maybe someone else can chime in and add to this, or correct me if I've given out any false info.

add to this a bit

the Makita EA7900 is the same as a Dolmar PS-7910. Not sure why but when Makita rebadged the saws they went back to the 7900 designation for the current saw

$322.00 is the listed price, but I've seen them go for as low as $275.00. I usually ask what their bottom price is. They usually have a little wiggle room from $322.00.
Put the 79cc top end on and the muffler mod and you're in business! Everything should be plug and play.

Nice im gonna go check it out never ran a dolmar but i want one i think i will put hd filter kit too

 

[Cracker Boy]

Are they open port cylinders

 

[huskihl]

Are they open port cylinders

6400 is open port. 7900 are bottom fed closed port

Because of the bottle neck in the HD filter elbow, the standard air filter flows more air. But the HD setup may last longer between filter cleaning

Can you make 6401 a 7900 by changinging cylinders

 

[SOS Ridgerider]

You need both piston and cylinder. 64cc is 47mm, 73cc is 50mm and the 79cc is 52mm.

 

[astnmacgto]

Yes both of mine came from home Depot and I talked them down to 300 each

The one. Bought from Depot had a pinched bar which made it throw Sparks bad. Needless to say I got a discount that covered a new Oregon bar and 2 Stilh chains
