Chain saw carburetor

That's the way I've been solving mine, Steve... with the caveat that when I take the original carb off, I put it (with any other removed rebuildable parts) into an oval-shaped plastic storage container strikingly similar to those found containing my favorite brand of Chocolate Almond  ice cream...

I haven't had a bad replacement carb YET... but at the price, I generally have two of each on my shelf.

The part that makes the most SENSE (and why the OEM doesn't see fit to replicate) is that when you buy one'a them carb kits, it comes with replacement fuel lines, filter, usually a spark plug and air filter.  The bar oiler pump, likewise, comes from the aftermarket in the form of a 'kit'.    Now, I don't put much faith in the spark plugs, but when I go through one of my saws, I disassemble, clean it all (including the muffler!!)  inspect the piston for scoring... then replace the carb and fuel lines, the oil line and pump, I scrub out the bar, flood the sprocket to rinse it out good, inspect it for damage, file off the burr, inspect the sprocket/clutch (replace it if necessary), then put it all back together with a new chain.

Darned few situations where I do all that, and DON'T have a good running, reliable saw for the season.  I've lost count of how many saws I have in my armory... probably a dozen... but they all get the same treatment.

I USED to use my saws until they'd have running problems, THEN tear them down.  I learned something really really amazing...

I found that they'd NEVER give me any kind of problems when I wasn't using them.  If they were on a shelf, sitting, they'd never flood or stall, they'd never have problems starting, or running... or oiling...  they'd just sit there, and wait patiently without a complaint...

But the very moment I took 'em out to tackle a task, I'd find problems... 

   so I'd hafta stop what I was trying to do, and carry it back in, and go through it.

So I started carrying TWO saws... that way, if one had a problem... I could determine wether it was from a bad batch of fuel (because the other one would suffer the same problem) or from some other situation... like a dulled blade... at which point, I'd stop what I was doing, and carry them BOTH in for a rehab.

So I started carrying THREE saws... the first two for the aforementioned problem, and the third, because invariably I'd be cutting through something and the first saw would have running problems, the second would wind up with a dulled blade... so I could pull out a third saw that was ready-to-go, insert it into the same kerf, continue the cut, only to find out that it too, had an immediately dull blade.

Then I'd get a fourth saw, and stick it in there, just to make certain that the rock buried inside that tree really WAS tougher than my freshly-sharpened chain...

(is there a theme forming here?  )

But really... I'll offer this advise to ANYONE...  If you want to be successful at accomplishing your tasks in a swift and efficient manner, accept my offer of experience... learn from MY mistakes!!!
