Ryobi Trimmer won't fully power up

kennykenny

I have a Ryobi trimmer 775R in which I have finally gotten to start but upon pulling on the throttle to increase the speed, the trimmer either stays the same speed or dies. Also, when I adjust the choke switch from A to B to C, when I move to C(or the run selection), it typcially dies but doesn't do die on B. Again, the speed will not increase.

Does anyone have any suggestions on what the problem might be? I have tried new gas, spark plug, new carb., cleaned out the muffler, checked the fuel filter, adjusted the carb settings. What else can I try? Thanks!

Run some Seafoam through it. Depending on how long you have had it, the float could be varnished.

Sorry, not familiar what seafoam is? Get at HD?

It's a magic elixir that every garage should have some of.
The others on that very short list are Sta-Bil, Techron, Marvel Mystery oil...
and PB Blaster. Get some of each today (at Wally's, AutoZone, etc).

I think you can get it at HD, but I'm not positive. Any auto parts store will have the stuff.

Regarding your question, there's about a 90% chance that you've got some old gas gumming up the main orifice in your carb. It's extremely common with oil-in-gas mixtures for 2-cycle engines.

The Seafoam should clean it out. If not, you may have to remove the carb and clean in manually.

Electric!

I bought my electric Ryobi trimmer recently, and I will never go back to gas.

Now that I've said what I really wanted to say, here's something more on-topic: How's your fuel line? My dads suffered the same symptoms until he replaced the line. Might not be your problem, but you didn't mention it in your first post. Might be worth looking at to at least rule it out, if nothing else.

I had the same problem, you have to put fuel stabilizer in the fuel, or take the piece of junk back where you bought it. Ryobi is the worst cusomer service I have ever delt with, very rude and cold. Try John Deere products, they work ten times better and their people are very nice.

Others will argue with me but I don't think ethanol was meant for small engines. You can get canned fuel without it pre-mixed with oil for two cycle engines. You should be able to find ethanol free gas at a marina too.

I don't like leaving two cylce fuel in things even for a short period of time.

Don't mean to insult you but I am sometimes known to forget the obvious. You did check the gap on the new spark plug right?

Never mind. Just looked at the date of the OP. I suspect sometime over the course of 4 months the things was made to run or was replaced.

I tried the Seafoam and didn't have an better luck getting the thing started. I didn't try the obvious with the spark plug gap but did try a new spark plug. I guess I assumed the gap was pre set at the factory. Maybe bad to assume?

Yep. Almost never right out of the box....
