Jonsered CS2149 to 346NE conversion - Need carb recommendation mild build

[RYNOSAWR]

Hey Gang!

So, I am finally about to get to my J’red CS2149 conversion to a 346 Xp NE OEM piston and cylinder, and I was trying to figure out the best muffler and carb combination for it.

I am planning on a base gasket delete, but I just cannot afford any port work and I don’t have the tools or the money to get the tools to port it correctly myself.

If someone reading this might consider a trade to do some port work, that would be awesome. I am going to list some items I have in the parts section of the classifieds (excellent used fuel tank with screw on gas cap for an 064 and 066) demo saw parts, brand new chain on rolls, lots of other stuff as I think of it.

I am wondering what carburetor I should try to get for it (or leave it stock) and what kind of muffler mod I should look at for a non-ported engine.

A Walbro HDA-198-1 is a nice bolt on upgrade, along with a 357/359 air filter and filter holder.

An option would be to buy @t4driller 353/346 and have him port it right away. Sell your saw and put money towards it.

As Joe said, a 198 is a great upgrade for a stock 346NE. As far as muffler just get a non catalyst type and put a second port on the clutch side, she’ll be breathing nice.

Like Onan said, 359 intake tract is an easy upgrade. Not very expensive. For the muffler just add a second port with deflector on pto side. Just gotta make sure to put it in correct spot so it dont hit case or burn top cover. Does your muffler have baffles in it or just a hollow can? With base delete, swapping to 359 intake tract, muffler mod, and bump the timing a hair they wake up pretty good. Will it keep up with a ported saw, no but it still will be a fun little saw.

What?
Only one I've done was an hd12. Doubt he wants to go that route

@t4driller how much advance have you seen them tolerate?

Simulpost! Lol!

Not much. Like 5 degrees. Sometimes a hair more. It does help with throttle response though. I tske a swipe or 2 with file and check it. Keys are cast in so you csnt just grab another key like on stihls.

Running a 199 on one of my 346's. It can be a little touchy to tune but I like it.

Adding a second port to the muffler definitely wakes them up. Just do whatever you have the tools for. A simple hole out the front will work even if it's not real classy.

I really like the EL42 on mine. Tune seems to stay true. Starts, idles and cuts great. I got sick of messing with the 199

What saws have el42’s on them for junk pile harvesting awareness?

 

[Backtroller]

Some 357 and 359s I think. Maybe the later ones? I’d like to know for sure if I’m correct in this assumption.

I buy new carbs off ebay. Usually 30 bucks shipped. Paid 25 shippes for a couple. All they had. I havent seen any on used saws. At my dealer tget are listed as 359 carb

Got ya. I don’t recall people talking much about 42’s vs the 198/199 conversions. Good to know

 

[beaglebriar]

el 42's can be had for around 35.00 on eBay. I'll try one eventually.
