Took back the junk weed-eater 2-cycle trimmer to wal-mart. Went to lowes and bought a troybilt 4-stroke trimmer. Except for it being a tad heavy, it starts and runs excellent. It holds a whopping "3.4" ounces of oil, and the filler hole doubles as the oil drain. Kinda weird, I have a 2-stroke lawnboy mower, and a 4-stroke string trimmer!

Glad to hear you're happy! What engine does that Troybilt use? I didn't know there was another common 4-stoke trimmer out there besides Honda (or the "semi" 4-strokes mentioned in the other thread).

It doesent state the manufacture on it. For being a little under $200.00, I would bet its the new briggs&stratton fource engine. My guess is they do this because they want the owners to be confused, and it might make them more prone to buy geniune replacement parts through their channels?

Check out Consumer Reports 6/04 issue for a complete test of string trimmers--very good summary. (I bought a Troy-Bilt TB25CS after reading their test--it was rated a "best buy"--haven't used it yet though)

Yes and no. You can turn them sideways and it will not affect lubrication. Most of those small 4-strokes basically atomize the oil, and it's just "there" in the crankcase (kind of like how it's suspended in the A/F mixture in a 2-stroke engine). You can turn those small 4-strokes 360 degrees with no ill effects.

The Troybuilt trimmer is a Ryobi unit. This machine does NOT like to be run on its side.

don't you think the people who design small trimmers, where turning it at many odd angles is part of the task probably considered this when designing it??

Sorry, I meant "yes and no" as in, yes you can turn it 360 degrees, and no it will not affect lubrication.

If the engine in question really is the Briggs & Stratton Fource engine, you can read about it here:

Found out that the troybilt 4-stroke weed trimmer engine is built by RYOBI die casting USA. They are makers of all the 2 and 4stroke weed trimmer engines used in MTD weed trimmers under the names like troybilt, yardman, ryobi, cub cadet.....

Here is a link to the Ryobi product:

It does claim that it operates in all positions.

They DO NOT run 360 degrees continious! The ONLY unit that will is the honda. If you run that Ryobi/Troybuilt or the Briggs on its side for too long it will die. I have been to many dealer meetings and have talked about these.

False advertising from the manufacturers? It says right on the websites of both that they can be used in any orientation. If I bought one and it had a lubrication failure from operating it like the manufacturer told me I could, I'd be right upset. It's good information to know...that they'll fail if operated too long upside down...but it strikes me as odd that they're marketed for 360* operation, but can't stand up to the test.
