Problem with homelite xl 923

[tico93]

Greetings!

I have a problem with my chainsaw Homelite XL 923. It was brought to my family by my grandfather in 1968 and it was running perfectly for almost 40 years. One day it just went crazy. It's running on full throttle all the time. I know that the problem is not the carburetor, because I had it cleaned up and fixed by a mechanic for old chainsaws. Since I remember we were using 50:1 fuel oil mixture. Does anyone have any clue what the problem might be?

I really want to repair it because it's a powerfull chainsaw and we would need something like that right now

Please help.

(P.S. I'm sorry for my english, I'm from Slovenia..)

Probably bad seals, maybe a bad gasket in the intake system. If it's running full throttle, don't run it until you get it fixed or it'll seize up, it runs lean.
Some times you can tell if it's bad crankshaft seals by turning the saw on one side, then the other, if it speeds up on one side or the other without touching the throttle, the crank seals are bad.
A saw that old, all the rubber parts should be changed(seals and diaphragms).

Check on the Homelite thread under chainsaw then chainsaw stickies, one of the guys there could probably give you part numbers and more specific information.

I cooked one of my Homelite 1050's because it was sucking air around the carb where I cleaned it out. I pulled the top of the carb off to clean the diaphragm. One of the 4 screws felt like it was stripping so I didn't tighten it down real tight. When it started racing wide open I kept cutting to finish the job, burned it up, Joe.

I got a Homelite XL 923 at a garage sale, old but it seemed that it has every ting at first sight. Decided to start working on it, unfamiliar I checked the manual on line: recommend 32/1 gas ratio.

this site here http://houseofhomelite.proboards.com/ deals with Homelites, I think they have parts manuals, etc.

Thank you Mike, I will check it right now. Happy New Year.

Yep, we ran 32:1, some of the older ones ran 16:1. As the newer saws started running 50:1 our saw shop said the 50:1 was fine, the new formula's lubricated just as good as the old 32:1. My Super 1050 that I mill with I run 40:1, but I have run it often with 50:1. That is not the one I burned up. I was running 32:1 in that one when I cooked it. An air leak is not your friend, Joe.

Good to know, thank you Joe. I can't wait to start restoring this saw. I remove the spark plug and started the engine, lot of sparks, love it. Fuel tank however has a lot of black deposits in it. Since I don't know much about working on it I will approach everything slowly and any information that I can get are very much appreciated. Thank you to all of you that for taking the time to enlighten me and others with your comments.
