scored piston

[Mike mandry]

I picked up a really nice looking Homelite EZ (an early blue one, made in 1971)

Anyway, it seemed to have decent comp, but I pulled the muffler & it had some piston & ring scoring. The rings were toast & they appeared to be on the verge of being stuck in the grooves.

the ring grooves were full of carbon & gunk, I assume from using cheap oil & or stale gas. The rest of the saw is in great shape.

I managed to clean the cyl up pretty good. I used 220 grit & scotch brite on the piston & it cleaned up OK

I have a new piston for this saw, but it is missing the pin. The pin from the scored piston fits, but seems just a tad too loose for my taste, so I think I will have to use the old one.

Anyone know whre I can get a set of rings for this & a cyl gasket ??

Id also like to replace the crank seals while it is apart.

I emailed Hawkins bros, but have not got a response yet.

Check out the pics of the piston & let me know what you think.

Scoring

I dunno. I never thought the piston being scored itself would make any difference since all the compression is really done by the rings. I think if you had a good set of rings and the cylinder wall is not scored you should be ok. If the wall is, you can probably get a machine shop to turn it. Hope it works out for ya dude...

Dont look too bad, it is a homelite your working with.


Were the rings stuck? Are they scored?




The blue saws, when their in good condition are some of my favorites.

RBW: yeah, the rings were scored, but not horribly. They werent completely stuck, more like all gummed up. Quite a bit of carbon in the ring lands & in the ring gap.

You wouldnt have a set of rings for this would you ??

Cosmeticly, this is a 8

I think I am going to run a 13" .325 bar on it. Its got a smaller bore than the SEZ, so I dont think it will do to hot with a 16" & 3/8

Nope, no rings.

I would like to set my SEZ up with some .250 chain, and an 8t sprocket, bet that would cut like gangbusters.


Pm me if you dont find anything in the next few days. I just found an outfit out of virginia that bent over backwards getting me some 925 parts. They got me 2 rods and 2 sets of rollers for them for $46!



Even managed to find me 1 ring from a shop near by them and drove over, picked it up and shipped the same day.



If the girl on da phone would have got me 2 rings I woulda married her.
