Sorry Vernon, just a little shell shocked at this time of year.. Most customers say that it never ran right since it was last in for work,
or they bring in a rusted piece of junk for sharpening, and oh yes, a
spark plug.
Most everyone does not bring in a saw, unless it does not run.
Most of them run the pis s out of them until the piston is damaged,
then they bring them in for the sharpening, and "tune up", or plug.
There is a small fraction of customers that will request a parts
install, because they see the need for it, not that the unit is running
poorly,but they see the part going south, and they want to nip the
problem in the "bud".
But that usually is not the case. If a customer brings a saw [or
whatever] in for a specific repair, i usually note the request. And as
well, I note on the work order, that if the requested request does not
make the unit, start and run correctly, I will call them and inform them
as such, but they still will owe for the parts and labor of performing
the original request.
Sorry if I got my panties in a knot in your case, but I deal with folks
everyday, and all of them try to get me to fix their equipment for
as cheap as they can, no matter if they are a deacon, or a crack dealer.
Just been there, and done that alot.
the readjusting of the carb, in your case, is fortunate that it cured
the problem, as a cracked fuel line will surely introduce dirt/crap
into the carb, as I would have informed the customer if it was brought
into my shop. Adjusting the carb richer would compensate, maybe,
for a while, but I would not take that chance, as I would have informed
you that going through the carb was needed from the getgo.
A cracked fuel line, in a carb box will ingest lots of fine dirt in the carb.
If someone comes in requesting a specific part install, I note that
when they bring it in, and if they claim the saw starts and runs great,
then I get real detailed on my comments on the work order, as that
throws up a huge red flag, because I have been there and done that.
When I worked at a mower shop in a nearby city, a local lawyer called
in to ask if we could sharpen the blade on his pushmower during his lunchbreak,
he would drop it off and come back by an hour later, he wanted the blade
sharpened, ONLY.
When he came by, it was stuffed in the trunk of his BMW. I went out
to get the mower out of his car, one of our lackeys followed, when we
were lifting the mower out of his trunk, he shouted, "Be careful!"
The lackey brought the pushmower in the shop, I went in a short while
later and removed the blade. I usede my impact wrench, but the
wrench zipped without resistance, a broken bolt piece came off with
my socket, but the end of it had dried jb weld on it.
He had broken the bolt, while trying to remove it, so he jb-welded back,
and took it to the local mower shop for just a "sharpening".
I work on all types of stuff, and if I am wrong in my earlier post, I apologize,
I just deal with all types, and have heard it all.
