Scrounging Firewood (and other stuff)

[sean donato]

The original 346XP is,a 46cc saw with no primer bulb. The 346XP New Edition came with a 50cc motor and a primer bulb. I never owned the early saw but have had 3 of the NE saws. For a small saw it can rip thru wood. I should have kept one of my 346XPNE saws. I sold my last two after buying a 2nd Gen 550XP.

My 346xp oe, is one of the saws that the kids will get rid of after I die. Cut a lot of wood with it at one point of my life.

Unless you are smart enough to construct a working venturi.

The venturi effect over the wings of an airplane enables it to fly. It is also what draws the fuel into a carburetor. The fuel pump just pumps to the fuel bowl. The level of the fuel bowl is determined by the floats, just like in a toilet.

If it can lift an airplane, it can lift some water!

Influence of Bernoulli’s Principle​

"However, Bernoulli’s Principle, which is closely related to Torricelli’s Law, plays a crucial role in the operation of carburetors. Bernoulli’s Principle states that the pressure of a fluid decreases as its velocity increases. In a carburetor, the Venturi effect creates a region of low pressure, which draws fuel from the float bowl into the airflow. This is achieved by shaping the venturi to create a sudden contraction in the airflow, resulting in an increase in velocity and a corresponding decrease in pressure."

Torrecelli theorized that we are surrounded in a "sea of air" and that if you put a tube in water, and evacuated it, the water would rise about 30'. That sounds familiar if you have worked with jet pumps or other low lift pumps. After proving this was true, he then surmised that mercury in a vacuum tube would only rise about 32", again, depending on elevation and other conditions. He proved this, also, then noted that the mercury level changed with weather conditions. A barometer.

Both Bernoulli and Torrecelli contributed a lot to fluid dynamics.

Minty 346XP OE , arrived today, anyone who knows or run these, knows what they’re all about,

Nice saw, so what are they all about .
Good thing you got those big ole dual dogs .

A late model "first gen" 550 smokes a 346, and your "second gen" does too, unfortunately they added so much weight to it you may as well grab a 60cc saw, then you're so close to a 462 you may as well...

Here we go again with the weight thing.

After lugging around a pm 1000 the other day, everything feels light now!

I did a clearing contract out west one summer and ran one of those. You knew you had did something at the end of the day.

If you are just bucking or milling, power to weight is not that important. That said, speed and power are always appreciated, so none of my saws are stock.

I try to keep a variety of saws to fit almost any circumstance. My ported 261 with 18" bar is nice and light and great for limbing, and my ported 044/046 hybrid with 28" bar has excellent power to weight and is great for difficult felling jobs.

If you are working far from your vehicle, and/or on a steep slope, and the tree is not 100% and has to be hinged at a certain height, power to weight becomes very important. It also becomes more important as you get older ... like it or not, your strength and endurance will diminish.

The 125’s are fun to run for a little while, but not a all day thing, Rather be holding my 592 ,

ALL of my saws have either rubber or spring anti vib. I will not work with a saw w/o it. I don't need to have spring AV, but I need AV!

All of my saws, including the 660s are either ported or "improved", and run very well. One of my Cross 660 cylinders has been fully ported, another is stock but has a base gasket delete, timing advance and muffler mod and it also runs very strong.
