20"-24" Saw Opinions

Thanks for all the advice on the 440. I snoozed and loosed. Got sold already. Must have been a good deal.

 

Don’t wait on the MS 261 then, it’s going to be gone too! But if you just have to have 24” bar capability then pass…

 

I think I'm sold on a 4910 20". I can do the exhaust modification and intake modification myself. I like the warranty they carry. After all, I'm only cutting pine (and clog my chimneys haha). If I really like the saw, I will buy a new one down the road and send it directly to someone to be ported. As a former motorcycle mechanic, I can appreciate working on something new vs. used.

 

I'm sold! I've watched and read too many reviews. The saw impresses me. I'll be ordering next week, most likely through Home Depot. Generally easy to get things replaced if something goes wrong.

 

Hey MasterMech, where have you been hiding?

 

I believe Sawdust Man has a minty newish Shinny 492 for sale at a respectable price. Same as a 4910

 

Truth.

I'm asking $325 shipped.

It's burnt about 10 tanks of e-free mixed at 40:1 with echo red armor.

Just listed it on evilbay on Saturday, but I'd gladly sell it direct.

 

Zack323 This hell yeah deal!!

 

What do you mean by 'tune them with no load at RPMs significantly outside their typical working range'? For me personally, I'm not looking to get too carried away. I'd like to scream through 16"-18" Ponderosa Pine or Lodgepole. At this stage in wood cutting, I could use a faster saw for efficiency.

 

The max rpm on my 350 isn't much higher than the rpm in the wood.

 

You basically turn the fuel up until it is over revving and “4-cycles” or changes tone.

that way when you’re hogging into wood hard, it’s got sufficient fuel to get the job done.

 

Nice to see you “stopping by”

 

That's not quite right. It doesn't over rev, it just spins faster than it does under load.

 

I hadn't thought of this, but most of my cutting is in the 6000-7000 feet range. Power is certainly lacking at this altitude due to thinner air/less air. As with a motorcycle, you generally lean an engine out at altitude. As I understand, the H/L screw is a fuel adjustment screw. The further out you turn the screw, the more fuel you are adding. Is that correct? 2 stroke motorcycles have an air screw which is counterintuitive as you open the air screw, you lean the engine.

 

You are correct on both

 

That means you lose roughly 20% of your power at 6-7000 ft. All the more reason to have a ported saw....You might still have stock power at altitude. We drove the old buick at 12,500 ft, and while the power was down, it still had plenty of go left.
