I have not tried saving a piston yet.
And he looks so tall in the video: not father of LepraWookie height at all.
Run it like you stole it!
Do you still use acid on a cylinder that has deep scratches? Like one that was seized.
If it has deep scratches, through the plating, the acid will eat the cylinder itself, instead of the alloy transferred from the piston.
Could this cylinder be saved? Is from a Jonsered 2258.
What should I use to clean it out?
Looks like a buffing with Scotchbrite would be enough to clean that cylinder.
Thank you guys for helping me!
Cleand the cylinder, the best I could!
That cylinder looks good.
My rule is to feel without looking..... (that's what She said).....lol
If you feel it, then at the microscopic level it's a gorge. However, carbon and oil will help to seal it up over time, somewhat.
Now i'm waiting the ring.
Ordered one at the local dealer for 10$.
I'Ll run from now on 33:1, synthetic oil. ULTRA from Sthil!
if you run ultra possibly be prepared for a massive headache.
Ultra is some of the dirtiest oils out there IMO.
And probably the worst smelling to boot.
X3... Smells horrible. And definitely not the best oil in my opinion

CristiRo (and everyone else) Be sure to remove that decompression valve and remove the spark plug,
then carefully clean flush out ALL of the remaining residue from cleaning the cylinder.
The cleaning pad will leave some (abrasive) grit behind, trapped in the crevices of the the decomp valve.
This will also be in and around the threads of the spark plug and the decomp valve.
We wouldn't want to run the engine with that gunk still in the cylinder.
That would negate all of our work when it scarred the cylinder and piston.
Best thread I have read here
That's what I just did.
I also had to clean de carbon build up in the combustion chamber, so the decomp valve and sparg plug had to be taken out.
All the best!
What did you clean/flush the grit out with
