I'm taking this Ryobi weed eater back to Home Depot, getting my money back and I will not be buying Ryobi again.

You are right Ryobi (a wholly owned Home Depot product) products are cheap junk. Take it back and get a good one.

I work with weed eaters and mowers. Weed eater fuel ratio is normally a 40:1 ratio. That usually all weed eaters fuel ratio.

Normal reasons for not reving are, blocked air filter, blocked spark arrestor in the muffler, or blocked exhaust port ( with carbon )

two cycle oil you can purchase from ACE, Menards,Home Depot.... the list goes on. Good Luck...

If its a 725r ryobi weed eater it takes a champion RDJ7Y with

a gap of 0.020 in. or (0.5mm) with a feeler gauge.

torque @ 110-120 in.lbs. good luck!

Try a couple fixes:
Air filter rebuild kit, and
Fuel filter rebuild kit.

Both kits are available at Home Depot but you may have to select ship to store if there are none in stock.

I'm not sure if Lowe's carries these, but I would imagine they do.

Please let me know if, and how, you may have already fixed the problem. I'm having the same problem with my Ryobi C430 4 cycle weed trimmer and am going to try the aforementioned fixes. I will check back and let you know if this works.

Good luck!!!

Go to sears partsdirect.com type in model no. of Ryobi you should have choice to see parts diagram, order part you need from sears.

SOUNDS LIKE YOU MAY NEED TO REPLACE THE FULE LINES THAY DO GET BAD OVER TIME

just cheap equipment. Mark it up to experience and do not purchase equipment fro home center or box stores ever again.

This is just one of the many problems of dealing with

the box stores rather than a full service qualified dealer. If you can

find one in your area, patronize them. Not just when the box store

lets you down but for everything. These type dealers are

disappearing and are not being replaced and soon they will all be

gone.

aside from carb adfustment. remove exhaust screen and scrape off carbon with piece of wood. also repplace the fuel pickup filter in the tank. couple buck at the home depot.
