I gotta ask

[bugfart]

Why did Homelite line up their ring gaps and right above the exhaust port?

This violates a deeply entrenched belief. That's where they go, there are little nubs in the piston and everything. Is this a built in governer?

You know what I wanna do right?

Ring gaps should go opposite each other and never over the exhaust port. NUBS ??????. I had the muffler off of my XLS 130 the other day to detail it and the ring gaps were definitely not lined uo in the exhaust port. I dont have an engine assembly manual for the Homy but having assembled a lot of motorcycle two strokes I have never seen it done. If you ever snag a ring I suppose you know they come to a real sudden halt. Im thinkin you would need to be ready to buy a new jug and slug. If the book states oterwise I would love to know, and if anyone knows where I can get a manual please let ne know.

Could the piston be in backwards?

 

[JohnL]

None of the Homelite's I've looked at had the ring gaps alligned with the exhaust port.

 

[HiOctane]

Have you got an arrow on the top of the piston showing a direction to ex?Does the exhaust port have a bridge?If no bridge,the ring end should not be in the ex port.

I have to ask the same question as Timberwolf. It sounds like the piston is installed backwards. No Homelites I've looked at had the ring gaps visible from the exhaust port.

The piston must be in bass ackwards, otherwise the gas pressure and the rebound of the ring would cause some serious ring clipping and a very short life.

A friend of mine just brought me a almost new 45cc Homelite that locked up on him. Bought it against me advice from popular tool center advertised as 'refurbished to perform like new', of course no returns all sales final. I pulled the head and find a broken ring facing the exhaust port. Piston had been installed so pin was at the exhaust side. Suprisingly it did not damge the head just broke off and locked the piston. Replacement will be facing the other way, and I will never let him forget it.

If this is on one of your 925's, yes the piston is in backwards.
ALL Homelites I have ever seen have pinned rings with the gaps on the intake side

It's the terribly scored xl923 miracle saw that ran for the previous owner.

On a more positive note the industrial oven cleaner proved to be an outstandig choice for the tar pit cylinder. Test subject 923cyl found a good 2 hr sitting will broke that stuff up. Do not get it inside the cylinder under any circumstance it will eat the chrome and pit the aluminum if left on it too long. Great for controlled use on caked on stuff.

How bad is it ?? have any pics

 

[bugfart]

Just got done touching up the cylinder, it's iffy... You have to look for it, but I'm surprised how well it came out. The saw has been apart, for sure. The piston, I'll get pics of that tonight I guess, is all scored and someone put on new rings and away they went for a little-while. Bizzar carbon pile-up like it was partially cleaned up once. The whole inside should have "falling carbon" signs.

A little carbon colony rides effortlessly between the rings.
