A few weeks ago I came upon two old saws. A Stihl 012 and the saw in the title. Both were considered junk by the owner. Compression seemed good, so I took them, free. The Stihl had some broken pieces and needed cleaned. Piston and cylinder looked good, so I repaired/replaced the broken pieces, cleaned it, tuned it and it runs and cuts great! The homelite needed a lot of TLC and the carb was way out of calibration. Anyhow, finally got it running and it cuts like a banshee. Except once I shut it off, it floods and won’t restart. Dry it out and it starts and runs fine. Any thoughts from the forum experts on why it floods after running perfect and being shutting off? I’m stumped. It idles in all different positions so I don’t think there’s an air leak, but is that a possibility?
Leaking past the needle and seat, stiff rubber, weak spring, worn needle/seat. That is where I would look first.
Pretty good bet, & make sure the fuel tank vent is open. It is possible to pressurize the tank & push too much fuel in after shutdown.
Thanks for the reply. This sounds like what is happening. The saw runs great. Shut it off, let it sit for a couple minutes and it floods and won’t easily restart. Let it sit for an hour or so and it fires right up and runs great. Any suggestions on how to check fuel tank vent?
Vacuum, or slight air pressure to the tank. It should bleed off quickly. I don't know that saw real well, but I'd run it till it's warm, then loosen the fuel cap & try to restart. If it still floods then it isn't a vent issue & quite possibly the carb just needing a clean & rebuild.
Got a chance today to test if the flooding problem is simply a fuel tank vent issue. It seems to be the vent. No flooding when I loosen the fuel cap. Fires right up after setting a few minutes. Thanks for the suggestion! Here’s a picture of this saw. It’s small but it cuts nice. I rather like it. It still needs some TLC. I plan on putting into the firewood rotation when finished.
Yep I think Screwloose has it. I have one those saws by the way and rebuilt the carb on it when I got. What great little saw they are.
