Makita EA3601...the most intriguing saw to date

[Backtroller]

They really did slim down the starter assembly.

The 420 has got some oil and petrol in the tanks and it's holding a bit of sawdust both are wearing the same bar and chain
The ps-352 is empty

The 420 does feel bigger I used the luggage scales to get a rough idea of weight
Ps-352 9lb
Ps-420 11-12lb

Though not as fat as the 420/421, it doesn't look like it will fall over too easily.

These pics may help sort out the airflow in these babies, and can anyone translate them?

Well, I still don't quite have the flow figured out. If I had the engine in front of me it would likely be obvious. I've learned to be cautious of any 'advertising brochure' from the marketing section of a company.

I do note that the flow through the second set of reeds moves through a very small set of openings. I expect someone will eventually open them up to see what happens. It will probably need a fair bit of carb work to dial it back in - but could make the saw really breathe.

Dolmar is spending some serious R&D time working with reeds in the strato system - they're on to something and they know it. The 6100 was an interesting design for a first try. Now this, - try a bit of this, a bit of that and then BINGO a 65cc saw with the power of an 80cc saw.

I wonder if Dolmar ever tested this design with a carb on the strato port. The fact it doesn't have an 'offset' combustion chamber to aide turbulence may give an indication of its original configuration.

Very very interesting......

I'm spending the next few weeks catching up. Then I'll get one to play with. It's great to see Dolmar/Makita stepping up to the plate on new technology.

The theory with the 6100 was that they were working around patents but I think this shined some light on it and they are using reeds to accomplish goals that can't be done without them

I'd love to see an animation....

In my mind I see being able to take huge gulps of air and get lots of primary compression to gain torque at low to mid RPM. Then at higher rpm when reeds alone would limit top rpm and are less effective, the piston port can do what it does best.
I can't wait to dig into it when it shows up!

Of course!
I'll be looking for insight from y'all...

Its good to see the modern small 2stoke is not following the footsteps of the dinosaurs. These products and new design concepts give me faith they will be around for a while yet and be the simple/strong/light & powerful alternative to the 4 stroke. I love 2stokes and their inherent nature all this stuff is promising!

Here's a few of the 420 and 352

Whats the new model for the previous 421?

You can't blip throttle on the 3600 series very much or it will load up the engine and stall.

Germany is very happy with the performance of the new generation saws they are testing. Can't say any more yet.

 

[fordf150]

@paragonbuilder what all extra pieces parts you want for your first attempt at porting this bad boy?


$17 for a piston, be cheap to try trimming for some intake and transfer timing changes

how much time have you put on this 3601? I got about 2 tanks thru mine now and its still impressing me for 35cc.

I can see this size saw being very appealing. I wish I was caught up.

New models are what keep my job interesting.

I prefer the size of my 346 over bigger saws. Id be interested in this new style in a 421 size

i think this saw blown up to 50cc with everything built the exact same way would be killer.

That is probably in the works. I honestly believe reeds and more ports will be the future.
