Thanks guys.

I will check out both Stihl and Husqvarna. This purchase is long overdue. I am ready to spend the money.

Also thanks for the tip on the premium gas.

I have a few more questions.

Does anyone have any thoughts about the chainsaw chaps or other specific safety equipment? The chaps seem like cheap insurance at $59.

Regarding the modes of failure on the saws...all of the above.

I am wasting too much time using and repairing the saws. They seem to just rattle apart.

I initially started out with three similar cheap lime green saws that the previous property owner left behind. Two are identical and one is slightly different.

From the three, I was able to make two working saws. The engine of the third saw, one of the twins, is seized up. I have canabilized many parts, including the housing, grip bar, chain bar, chains, adjustment screws, hand start recoil mechanism and chord to replace broken items I can remember.

On both working saw the bar adjustment screw rattled loose and disappeared.

On any given day one or the other won't start so I am swapping the remaining bar adjustment screw depending on which saw is in the mood to work.

Neither saw likes to come up to speed and has to be nursed.

The crankier saw leaks chain oil pretty bad.

Right now both saws are on my bench and I am out of cheap parts. I need a recoil chord for one saw and a chain bar and probably a chain to get other saw working.

Even when the saws are working, the blades dull very fast going through oak. It seems that I am spending more time sharpening than sawing.

The chains don't stand up to much sharpening either. I have used hand files and a Dremel to sharpen and destroy the blades. I am also considering a bench sharpener. Any thoughts?

Besides the saws' mechanical shortcomings,
The trees I am clearing are bigger than the twenty inch bar can handle, going all the way around. I need at least three more inches of bar to get through some trunks.

The one cool thing about this project is that I live in a rural area and I have a well tested burn spot on my property where I can safely and legally burn the debris as I go along. We are having some nice evening bon fires.

Thanks for all of your advice.
