My new Poulusqavarna 2941 saw

[GeorgiaVol]

I had a fun project this past week that I thought about doing for a while, and now I'm almost finished. Basicly I took a 46cc Poulan 2900 engine and put it in my Husqvarna 141 case. I like the anti-vibe on the Husky better as well as the overall build of the saw. I also kept the .325 pitch sprocket and intake partition and changed the muffler to a new less restrictive muffler. I hope to try it out tomorrow.

So you took the p/c of the 2900 and installed it in the husky. Have to mod the cylinder flange?

Didn't modify anything other than a small bit on the partition where the fuel line comes up.

Nice - I know this has been done before, but I have wanted to do one as well. However, my 142 runs too well to mess with. I'll be curious what you think of the vibration level of the 46cc engine compared to the 40cc. Did you have experience running it with the original engine?

I've had a pet theory that the counterweights were only marginally big enough for the 36 & 40cc versions of this engine, and that the 46cc versions shake a lot. Many of the failures I've had on my 2775 were due to excessive vibration.

They are clamshells using the same engine design, both made by Poulan. The chassis are different.

I have run 2 other 141s but sold both. This one had bad bearings and the 2900 had a destroyed case. So perfect time to try something new.

It does have a couple minor upgrades. The 2900 saw must have gotten the case bolts loose because 3 were broken off and I had to drill them out. So I drilled and tapped to the next larger size.

Rain, rain, rain. So depressing. Guess wood cutting will have to wait another day..............

That's how it's been here also. Stopped to test a saw yesterday and got soaked..

I have a few poulan 295s and I like them,I like the motor even better in the Husqvarna chassis.The antivibe is much better.

 

[GeorgiaVol]

That was my hypothesis, but nothing but rain today. So I havent even tried it yet. I also like that since I kept the .325 sprocket, it can share bars and chains with my PP335

I've been curious about engine swaps on saws. So this is pretty interesting to me. I don't own enough saws to try it.

Did you guys notice if either one of the saws had a larger carburetor?
Did you use the husqvarna carbs & intake, etc or the poulan?
Ive got a 2900 superclean, somewhere mixed into my clutter.

The anti-vibe was super smooth, but it always felt like you were working with a water balloon.
( I grew up on rigid framed saws)
Took me a while to get ever get accustomed to the way relationship of the bar to handles, would change when you went from a bucking cut to a felling cut.
I goofed a few hinges till I got it in my muscle memory.

I used the Husky carb because my 2900 Didn't have one. I compared it to my 4620 Walbro carb and it just looked like the Zama version of the same carb.

My 40cc 142 has the same 34/64" size carb as my 46cc 2775. Or it did until the 2775 carb got bored a bit.
