Hi LaoMao. Thank you for inquiring about the RYOBI Expand-it 25 cc 2-Cycle Full Crank Gas Power Head. This RYOBI Power Head has a 2-cycle engine so it requires a fuel mix of 50:1 which equals 2.6 oz. of 2-cycle engine oil to one gallon of gas. Thanks! -Dina

It is still for sale at Home Depot for $159.00
The best thing I can recommend is to contact the Ryobi service center (go to there web site for the phone #) to find out if there is an authorized service center in your area. They are able to order parts and repairs for problems like this. Be advised based on your question and the repairs you have done on your own may have voided your warranty, but the Ryobi service center will be able to give you more info. on that. I hope this helps.
Thank you Benz for your inquiry. The item can fit most brands we recommend taking the unit into Home Depot to try it on a display.
Get the Electric Version. Less hassle, no gas, then buy a 6 amp battery, lasts 45 minutes cuts really well. (Battery it came with last 20 minutes, not a slouch) This gas model has sat in my garage most of the time unused, a waste of your money, IMO.
I have 3 Ryobi trimmers, one i owned for 10 yrs, over the years with all 3 they always gave trouble starting, the older one started the best but had a rough idle that i lived with ,i have discovered if you stay away from cheap gas use a little higher Octane & straight no lead you will have less trouble but many right out of the box have the Carb. adjusted too lean so when you move the choke to run position it`s lean and stalls or just won`t run . Having the Carb. adjusted by a repair shop may help, it takes a special tool !
It sounds like the engine has a major problem. Depending on the age, it may be und er warranty. My second power head did th he same thing not long ago. Without going into detail, I think the engine is worn out. Mine was about 3 or 4 years old.
