Hi All, I was given this Ryobi brush cutter not working and am trying to bring it back to life. I have never had one so all new to me.
When I received it it was all covered in oil. I expected there was a leak so cleaned it whit a degreaser solution. I emptied and washed the fuel tank which had some melted rubber ring inside (maybe from the cap) on very old fuel.
i took the carb out and it seemed clean, so did not want to mess with the gaskets or diaphragm as i saw someone in youtube saying Ryobi doesn't provide kits anymore. The carb is a WT148A I then replaced the air filter (made my own out of foam) as it was almost non existent Checked the spark plug and looks clean and new. I investigated the petrol/oil mix and the recommended seems to be 25:1 so went to bunnings and bought the Ryobi 2 stroke "high quality" oil and prepared a small amount of fuel for the initial test.
After a few tries I managed to get it running but it died out after some 10 seconds or so. I never got to switch the knob to the run position. The problem seems to be a large leak showing at the exhaust. I opened it up, removed the plastic cover at the back (where the air filter is held) gave it a wipe and tried to start it with the cover off. this was not a good idea as it seems to shoot fuel out of the carb (through a hole which would be normally blocked by the choke knob.
When I took the cover off, there was a small amount of fuel around the carb but the exhaust had a lot more. I am not sure whether the leak is in the exhaust or whether it is dripping into it from the carb (which is located right above it) I managed to get the cutter started a second time but again died after a few seconds. Once it dies I had to try hard to get it to start again and the fuel seems to be pouring out of the exhaust.
