being a 4 stroke, can you run ethanol gas with out damaging the carburator like the 2 stroke

Asked by: br549
You can run 10% ethanol, but the user manual discourages E-85 gas. Alcohol-free gasoline is best, because it is less likely to gum up over time. Always use a fuel stabiizer, and filtering the gas is recommended, as passages inside the carburetor are extremely small.

Brought this with a brush-cutter to take care of the fence-line at my country property. Used the trimmer at my home and it work beautifully. Got out to the property and I couldn't get it to stay running, then it wouldn't start at all. While it was running, the brush-cutter worked well. It was knocking out large brush without a problem. I was going to bring it back to Home Depot because I couldn't get it to restart and decided that I needed to try it again. It has started flawlessly at home several times. Will see what happens the next time I get out to the property.

Rated 5 out of 5 by from Complete Monster! This thing is a beast! A total monster. As can be expected from a 4 stroke, this thing has tons of power and torque. It is a little heavier than the two strokes, but the power is worth it. I pulled it out of the box, read the directions (actually important), added the oil, and after some assembly I was ready to go. I followed the directions and it started with two pulls, but stalled. It was cold outside. Two more pulls and it was running. I had no problems cutting heavy brush, twigs and stuff. You really need to be careful, because this thing can really launch rocks and stuff. I love the string head, but I did need to take it apart for the first reload because the line broke inside the head. Cleaned up most of my acre in a few hours. You'll never go back to a 2 stroke.

After decades of dealing with balky 2-stroke outdoor tools, I am fed up.Since I already had a Ryobi 2-stroke trimmer, which was so hard to start that I began to develop shoulder problems from trying to get it running, I decided to try the 4-stroke head unit only, as my trimmer attachment would work with it. I have only used it for a few hours, but so far, I am very pleased. It starts every time with 1 or 2 pulls. The only difficulty I had was on the first start, when the engine would not turn; I removed the spark plug, sprayed some WD-40 in the combustion chamber, and gave it several pulls until the engine turned over easily. Put the plug back in, and it started on the second pull. I was alarmed by the number of 1-star reviews, but after reading them, I am convinced that most, if not all, bad experiences were due to owner ignorance. 1) Small engines have small carburetors; small carburetors have extremely tiny fuel passages. With a 4-stroke engine, NEVER let it sit for a long time with fuel in the tank/carburetor. Drain the tank, then run the engine dry. You can't do this with a 2-stroke, because the piston needs the oil in the gas mix for lubrication. If the carburetor is not drained, then fuel will evaporate, form varnish, and eventually clog the tiny fuel passages. If at all possible, use alcohol-free gasoline, which is less prone to form varnish, and add an ounce or 2 of Stabil or similar fuel stabilizer. When in doubt, toss the fuel, and start with fresh gas. 2) A 4-stroke engine has an oil sump. On this 30cc engine, the fuel sump holds only 2.2 ounces of oil. If you let the oil run low, or use the wrong grade of oil, the engine will almost certainly be damaged. CHECK THE OIL LEVEL EVERY TIME BEFORE STARTING THE ENGINE. Use 20W-50 conventional oil, or 15W-50 synthetic (such as Mobil 1). These heavy grades of oil can usually be found in a motorcycle oil section of an auto parts store. When held in the "normal" operating position, the oil sump will be at the bottom of the engine. DO NOT operate it 90° to vertical, or upside down. The tool attachment has holes so that it can be rotated at 90° intervals. If you use the engine at any other angle, the oil sump will be starved, and the engine will be damaged. 3) Not related to the 4-stroke engine, but several reviewers complained about plant matter wrapping around the shaft. There is a gap between the cutting head and the tube. This gap exists so that you can get a wrench on the shaft, but the opening can trap plant matter, especially if you are whacking tall grass. My solution was to cut a second of soda can about 1/2" wide, and wrap it around the upper body of the gear box, closing the gap. I used doubled sided tape between the aluminum and the gear box, then secured the aluminum with duct tape. Then I took a piece of semi-rigid plastic sheet, ~1/16" thick, and about 5/8" wide, and secured it over the aluminum. This overlaps the spinning head assembly, without actually rubbing against it. With the gap closed, even the tallest grass no longer gets caught. 4) I have never used a bump feed trimmer that I liked. They all jam eventually. I replaced the bump feed trimmer with one that has two slots for pre-cut 0.95" cutter line. When the line wears down, I just push out the old pieces and slide in new ones. I gave this 4 stars because I have reliability concerns about the plastic camshaft (I haven't actually checked to see if it's still plastic, or if Ryobi has upgraded to metal). If well lubricated, the plastic should hold up, but there is very little room for error. Use the wrong oil, let it run dry, or hold it upside down, and the engine is almost certain to be destroyed. If the 4-stroke power head continues to work reliably, I may add other attachments. If it doesn't, I will update my review.

Rated 2 out of 5 by from adaptable Purchased post-season, less than a tank of gas through it so far. Tested the included straight shaft trimmer, and, also, my old curved shaft trimmer from my 25 year old Ryobi, 2 stroke that I'm finally replacing. I'll be using my collection of attachments that have served me well for over 2 decades. I'll use this machine year around, for my snowblower, hedge-trimmer, cultivator, leaf blower, and the 2 string trimmers. [This review was collected as part of a promotion.]

Rated 4 out of 5 by from DON'T WALK INTO THIS TRIMMER BLIND! So you saw this little whipper snipper at the store and you aren’t really sure what you are looking for; you don’t know what 4 cycle means and you just want to replace your old 2 cycle trimmer. IF You Do Not Want Your Life To Become More Complicated Go Back And Purchase A 2 cycle Trimmer! If you are curious about 4-cycle and why this thing has such bad reviews than I can help, read on: First, this trimmer is a beast! Low end torque, easy starts, great idle, terrific throttle response, less exhaust, less noise. It’s great! 4 cycle motors offer a level of refinement above their 2 cycle counterparts. I use only pivot heads, and this thing has no trouble spinning up four doubled up .095 lines! My 25cc 2 stroke trimmer would simply bog down and die mid throttle with this set-up. I never use auto feed heads, nothing but trouble, including the one that came with this trimmer, or maybe im just cursed. I prefer pivot heads, I find them more convenient in the long run. Here is the quick and dirty on what you need to know if you buy this trimmer: -This trimmer has an oil pan like a car, YOU HAVE TO PUT OIL IN IT, check the oil level periodically and change it about once a season, just like you do in a car. 1 qt of a nice synthetic oil will serve you for years and years. Caution – Over filling will damage the motor – consult the manual. -There is a maintenance interval for valve lashing; you can do this yourself with cheap set of feeler gauges. You can look up a How-To on the internet. You don’t have to do this on a 2 stroke but no need to cry about it. -You cannot flip the trimmer it on its side for edging, instead you have to flip the head shaft, which is not nearly as convenient. It is also a pain for head attachments like pruners or the chainsaw Ryobi even put pictures of these attachments on the box, no wonder consumers are confused! I wouldn't recommend any of those for this trimmer, it was made to operate in a horizontal orientation only. This could be a deal breaker for a lot of people. -You HAVE to store it horizontally or vertically with the engine down and trimmer head up. If you don’t oil will go in bad places and lock up the motor, don’t worry you can easily fix it, just don’t try to start it in this condition – consult the manual. -The box recommends using an ethanol fuel treatment / stabilizer. In reality you should do this on all of your lawn equipment. But good on Ryobi for throwing that info on the box. A lot more info should go on the box of these trimmers so unsuspecting consumers know what they are getting into. *If you want a 4 cycle trimmer that can be oriented in 360 degrees you are going to have to spend the extra money on a Honda. But that technology does not come cheap* What you should know about all of the bad reviews for this product: Almost all of the bad reviews for this trimmer are a result of people who did not understand how to properly use, maintain, and store this 4 cycle trimmer. If you read this review, you wont have that problem. No one reads manuals except for me apparently, Ryobi could do more to make this essential info more accessible, such as a blurb on the box. THESE TRIMMERS DO NOT HAVE PLASTIC CAMSHAFTS! Ryobi addressed this question in September of 2015 in the questions section. People have inspected their trimmers and found metal camshafts dating back to 2013. The user that had a plastic camshaft may have had a really old unit or another model all together. With that said, a properly maintained motor, even with a plastic camshaft should be fine. See the review of the gentleman who has had a Ryobi 4 cycle over 8 years. These are quality units but you cannot treat them like your old 2 cycle trimmer, 4 cycles require more maintenance.

Rated 1 out of 5 by from Not Worth. It worked fine for 9-10 months. Then it started to leak gas from the cap and latter on I was not able to get it to start it. My first Ryobi 2-cycle string trimer lasted about 4-5 years. My second Ryobi 2-cycle string trimer lasted about 2 years. Bad quality. WILL NEVER CONSIDER PURCHASING ANY TOOLS FROM THIS COMPANY.
