Question on Homelite E-Z piston

[Ax-man]

Did Homelite experiment with something like a ringless piston at one time, dumb question I know, but I really don't know how else to explain it. I've been working on some E-Z's to get them to run again and came across this different looking piston, the top of the piston appears to take the place of the rings.

I took some pic's to show what I'm talking about, first pic is of two saws, left one has the usual two rings, the right one is the odd one. Second pic is of the odd looking piston but closer up to show what I'm talking about.

The saw has point ignition and is the red and white color, if that helps tell how old the saw is, darn thing has compression but not much fire, that other saw is going to be a donor saw to get this one running.

Caution the pics haven't been resized, they are a little on the big side

I'm pretty sure theres a ring on there, its just kinda hidden, and matches the piston color pretty well.

I have one of those EZ'S also.

they call it a "Head land" piston ring.

Mine does not run, but it is in line to get fixed up, just needs a little TLC

I know they have a smaller bore than the SEZ (I think)

Ive got some info on it somewhere around here. I will try to dig it up & post it.

Mike,

Would the bore be the same as the blue E-Z ? I might have to swap jugs from another saw to get this one to run good. Oh, thanks for the help.

I think as long as they are both EZ's they are the same bore. The Super EZ has a bigger bore and the stroke is different.

I lucked out on this one, fixed the ignition, wire on the cutoff switch wasn't attached that explains why it had little to hardly any spark, put a new carb kit in it and did some Mickey Mouse adjustments and got a good running saw. Saved me some work from having to tear it down to the bottom end.

Thanks for the help on this oddball piston. If I run into another one I'll know what I'm looking at.
