028 intake port.

[Mathewsdxt75]

The intake port on this 028 an has this little nipple on the piston side, can this be removed when opening up the intake port?

 

[P.M.P.]

I don't know because I just *f-word chit up if it were me I would ask or send it to this guy @tree monkey

Can thin it a little but cannot remove it, holds the ring ends in place.

I did what you thought you would do....
CHIT is an understatement.

I guess I will slide the cylinder back on and see how bad I flubbed it up.

Yes, if you eliminate the bottom ring.

 

[Mathewsdxt75]

I put the cylinder back on and see that both ring ends are on either side of the intake opening and supported by the cylinder wall. But I do see how the bottom ring may not have enough support. Since I removed the little nipple, I assume it is a consensus that I screwed this jug?

 

[Adirondackstihl]

I screwed this jug?

Yep.......Unless you run a top ring only.
What bore is that?

 

[Mathewsdxt75]

44mm.

 

[Adirondackstihl]

44mm.

Hmmmm
I have minty 42mm I'd trade ya.
But that would be a slight down grade on your side

 

[Mathewsdxt75]

Thanks but if anything, bigger is better.

 

[blsnelling]

Ditch the bottom ring.

Is the whole ring into the intake port at bdc? Maybe a base gasket delete (If possible) would lower the cylinder enough to keep the ring above the intake opening. Or like Brad mentioned, leave the bottom ring out

Nah
The gasket would need to 0.1875” thick....lol

Oooh. Dat's a bunch

 

[Adirondackstihl]

Oooh. Dat's a bunch

Well.....maybe not quite that much, but it would def need to be thicker than the stock 0.020”

just stake the bottom ring center of port, the rest of the ring will still serve a purpose

 

[Mathewsdxt75]

With the base gasket out, even the top ring just barely starts to peek into the port at bdc. I think the top ring will be fine, but then I thought taking out the support nip was ok

just stake the bottom ring center of port, the rest of the ring will still serve a purpose

Damn... that is a very intriguing idea....

Do ALL oem stihl cylinder have "Stihl" cast into them?
