Ifixoldjunk 778 #1 Posted September 8, 2022 So I’ve ended up with another old homelite XL-12. When I got it, it was locked up solid. My initial thought was it was probably heat seized. Until I pulled the plug and muffler and found… Sand? Speedy dry? Something gritty? But like big chunks that probably wouldn’t make it past the carburetor. Almost like it was intentionally dumped in there. I cleaned it out and broke it loose. Seems to just have one scoring mark by the exhaust side of the piston. It will run for a second until I give it some throttle. Perhaps it still has the compression to run? My question is why was there so much damn sand in it? It was basically enough to fill a teaspoon. Im thinking it was intentionally sabotaged at one time over the last 30+ years. Maybe the boss man wasn’t giving the employees new equipment? Maybe they just didn’t wanna cut wood that day? Idk. Regardless I hope to get this one running. It looks like a nice low hour saw. It has the original 24in bar as well. Most of the paint is good as well. maybe someone tossed some sand at a unknowing lumberjack? 2 1 3 Share this post Link to post Share on other sites
WHX?? 48,815 #2 Posted September 8, 2022 Had an engine come to my shop once with sand in it. Push mower parked by a sand box and kids... well their kids... 1 Share this post Link to post Share on other sites

lynnmor 7,305 #6 Posted September 9, 2022 I suspect that the white stuff is corrosion that formed inside the engine. Are you seeing sand in the intake or exhaust? 1 Share this post Link to post Share on other sites
Skwerl58 704 #7 Posted September 9, 2022 That looks like the stuff that was in my gt14 bowl when I started on it. A gritty, dry sandy texture gunk that I am still wondering what it was. Cleaned up and rebuilt the carb, changed fuel lines and hope to get it going soon. 2 Share this post Link to post Share on other sites

Are you seeing sand in the intake or exhaust? I picked up an old 50's boat motor and pulled the plug to see if it would free up. It had several teaspoons of Aluminum corrosion just like that.. Thankfully I just wanted it for a wall hanger! 1 Share this post Link to post Share on other sites
Ifixoldjunk 778 #9 Posted September 15, 2022 (edited) Well, after a slight carb adjustment she’s building chip piles again. Got real lucky on this one. honestly baffled how this still runs, let alone with 150PSI compression. Has slight scoring on the piston. I’ll just use it as my beater saw. It’s rough all around but seems to run like a top Edited September 15, 2022 by Ifixoldjunk 1 Share this post Link to post Share on other sites
