My keeps stalling after i removed all parts and clean things out.
So for a week i wasn't able to get my to get my ryobi start. So i took out the spark plug while in the process the trimmer fall from my hand and on to bucket of used oil so it was covered with oil. I clean it off. Put the new spark plug in. give it a try. it didn't work right away. I came back the next day. Finally it start but would stall out like 5seconds after it starts. I took it apart clean any extra oil. didn't see any gas leaking. cleaned out the carborater. still stalls out. Please help.

When in doubt, clean or replace the plug first. Then, if I get spark of any kind, I'll call it good for now and verify three other things. 1) pull the spark plug, ground the plug wire and turn the engine over to verify compression. Put your thumb over the hole and you'll feel it. 2) fuel - is it fresh and clean? not more than 6 months old with no water, and a clean filter. 3) Be sure you have clean and unrestricted air filter and passageways. If it all looks good, start looking at electrical wiring back to the magneto (things that might drain current to the plug). Keep in mind that a slight nick in a flywheel key can affect timing enough to keep a small engine from running.
i was given one of these trimmers thats almost new but missing a bunch of parts so im seeking one that owner declares as 'junk'. ill buy and pay cash. locked up okay, blown engine ok, just need handle and body parts with aircleaner assly. anyone got one to sell me? seven06 three22 fourthree79. call mark, regards!
Hey www_mike350, Just fixed my Ryobi 3043YW. I got this given to me not working and didnt even need it. I already have one. I decided to have a look over it, see if I could get it going. To my surprise everything looked clean. I checked for spark, that was good, compression seemed good. I took the spark plug out and tipped some fuel in the cylinder, put the plug back in and tried to start it. If it started I would have suspected the carby, but it still didnt start. I was really annoyed because everything looked clean but it still wouldnt start. There was fuel, spark and compression, I didnt know what else could make this thing not start. I pulled it completely apart and found the rotor assembly was the problem. It was causing a timing issue, meaning that it was sparking at the wrong times, when there was no gas in the cylinder. On the inside of the rotor is a pin or a key that lines up on the shaft and gives the spark its timing. That key was made of cast iron and had broken off, causing the rotor to spin on the shaft out of alignment. This through the timing out. I lined it up and tightened it and its working again. I couldnt believe it when it started, I have spent hours on this thing. I will have to try and replace the rotor (Part no. 300952001), otherwise it will slip on the shaft again sooner or later and do the same thing. Unfortunately I need to replace the gaskets too now as most came apart when I was pulling it apart. Hope that helps someone out there! email@example.com
Assuming you still have evidence of fuel in the cylinder after carb work; and still have visible spark across the plug, I would install a new spark plug. It is fairly common for a spark plug to cease working under pressure in a cylinder while appearing ok outside of the engine.
Stihl weedeater was running and stopped suddenly. Put in a new fuel filter and cleaner air filter with soap and water. Checked spark plug and it appeared fine. Started the weedeater, ran for a second or so and stopped. Spark plug wasn't gas fouled. Could it be the carburetor needing new diaphram gasket and spring.
I don't mean to over simplify this, but are you using fresh gas? Gas string trimmers are extremely ticky when it comes to gas. They like it SUPER fresh. And while the gas and oil mixture should be right, it can be off a little bit and still run. Try draining all of the gas out, and then filling up with fresh mix. This is ALWAYS my first step with string trimmers, and it fixes the problem 75% of the time.
Hope this helps!!
