would you think the chainsaw would still work like this? The sides are not scored at allSomebody trying out his aluminum welding skills while also increasing his compression?
craters lolAre those craters or bubbles? Cool.
i think so because all the craters are pretty much a perfect circle. Do you think the chainsaw would still work like this?I would think somebody sucked up a mouth full of bb's but it's probably a ball bearing that fell in through the carb.
none whatsoever. Only damage is to the top of the piston and cylinder.What does the under side of the piston look like? Any cracking?
possibly, the only thing is I found nothing in the combustion chamber which I managed to unseized with heat. Would you think i could weld in the holes and sand it down?Could it possibly be a butterfly screw?
ok thanksI think any repair attempt would add risk. I’d blend down sharp edges on piston with a Dremel polishing something-or-other. They make a rubbery wheel with embedded abrasive. The outer edges of crown may be peened outward so maybe flat file the edges back to cylindrical. Ring groove may be crimped below peening too. A jewelers file may address any of that.
Then I’d assemble and run. No way I’d weld it.
I'm not very bright sometimes so if you care about this saw Id fix it right. Cold-hammering aluminum with a ball bearing probably put invisible cracks in it.ok thanks
You mean repace the piston?I'm not very bright sometimes so if you care about this saw Id fix it right. Cold-hammering aluminum with a ball bearing probably put invisible cracks in it.
