I mean, sure I have already made a profit off the lot, just by selling one trimmer, that I got for free, entirely apart from this lot of trimmers, so I'm already in the positive on them.
Anyway, I'm getting sidetracked. Regarding these two Poulan trimmers, unfortunately one was missing the head, and missing an air filter, and cover, as well as the spark plug. Sure, I have a few plugs around, from salvaging out of other trimmers that were pulled apart for parts, but the parts missing from it made it that I simply cannot actually get it started.
I'll be ordering some replacement parts for the trimmer, such as the air filter cover, gas cap, and primer bulb. It would be good to have the two working, as they can easily turn a pretty good profit, considering the whole lot is already bought and paid for in full.
On to the repair of these machines, and honestly, it was interesting, to say the least.
I started off with a spark test, to confirm that, yes, I am getting consistent spark, which I was. That's a
good sign, I'm sure. Next, I decide, let's check the engine compression, to make sure I'm working with a good engine, which, honestly, I was pretty sure I was, but just to make sure... And this is where things go a little downhill, and that's because of the compression results. 76psi. That's not a good sign at all!
But the weird part, is that I got the same reading from a Homelite trimmer. To put that to the test, I decided to test the other Poulan, and sure enough... exact same results!
There's no way that I can use that tester on two three different machines, and get the exact same results, without calling the tester faulty... Although to be fair, it isn't technically faulty, it's just horribly inaccurate with engines of that size.
Larger engines, such as on Lawnmowers, it is much more accurate, and gives very good results.
Next was checking the piston, and cylinder out. That meant, pulling the exhaust, and sure enough.. Springs! Oh how I love springs (no I don't)...
That was an entirely new challenge.. Pulling apart the machine was pretty simple, it was only a dozen or so screws, and the machine was apart.
Then I was confronted, face to face, with the dreaded spring restraint exhaust. I do not like those, and would much prefer they have bolts, as springs are nothing more than stored kinetic energy.
They can cause much pain!
Well, I fought and fought, and sure enough, got the hooks off... The cylinder looked perfect, as did the piston. Ring moved just fine, and so I put it back together.
But I had to fight with the machine, as those springs really did put up a fight, and didn't want to go back on.
Carburetor was then opened up, with the diaphragm being a rock.. hahaha! It was hilarious! It was as stiff as cardboard, and would do no pumping... So carburetor was put into a Mineral Spirits bath, inside a glass jar, then placed into the ultrasonic cleaner for about 20 minutes to get nice and clean. And nice and clean it was!
Bought a new diaphragm for it, shipped from Amazon, put the carburetor together, reinstalled it on the machine, replaced the fuel lines, reinstalled it on the shaft, added fuel, and....
Took it outside for its first test... and sure enough! It fired up just fine and dandy..
Sounded fantastic!
It's always satisfying when a machine fires up after you've repaired it.
