Questions & Answers

My blower won't throttle when pressing the trigger, it starts when choked and stays running until the motor is at operating temp.
Greg for model number TB2MB asked on 2020-03-10
Hello Greg, thank you for your question. We would recommend checking the throttle cable and carburetor on this unit. It may be a fuel issue or the cable may not be connected properly. I hope this helps.
Why does this trimmer continue too stall after using it for a few minutes, the carb has been replaced and the spark plug is new also, this is an ongoing issue

this blower I'm not use during winter. Last month I tried to star it but it did not run. I think something is wrong with the spark plug. I replaced the carburetor and spark plug and it still did not start.
hiep for model number 41AR4BEG966 asked on 2018-10-02
Hello Hiep, Thank you for the question. I suggest checking the filters to make sure they are clean. Also check the recoil spring and rope for any wear or damage. You can also check the Leaf Blower Ignition Coil/Module, Part Number: 753-06003. Hope this helps, good luck with this repair!

I had a pinched fuel line, and since I had my trimmer tore apart I wanted to tune it all up. I didn't want to rebuild the carburetor so I just replaced it with a new one.
1. Removed the cover to the air filter
2. Removed the 3 screws holding on the outer cover
3. Loosened the bottom two screws on the lower outer cover.
4. Slide the bottom cover back, and pulled the gas tank out.
5. Removed the two screws behind the air filter, pulled them out and slid the carburetor up.
6. Hooked the new gas tank line to the new carburetor. Ran the line from the carburetor to the primer. Then ran the primer overflow line back to the gas tank.
7. I slid the carburetor in replaced the two screws, then slid the new gas tank in. Tightened the bottom two screws that were just loosened to hold the gas tank in place. Replaced the top cover put the final three screws back in. Then changed the spark plug. It fired up on the second or third pull and ran better than when I purchased it new.

Repair Difficulty:
Easy
Time Spent Repairing:
30-60 minutes
Tools Used:
Screwdriver, Socket set, Torx driver
1. Removed old fuel lines, filter, primer bulb. Lines and bulb cracked apart due to age.
2. Replaced fuel lines, filter and primer bulb with new parts. I had to remove the preassembled fuel filter from the fuel line so I could feed the new fuel line into the tank from the outside. Once the line reached the opening for gas I reattached the fuel filter to the line. I have no idea how the fuel line can be fed through the fuel line hole at the top of the tank from the inside of the tank on my Ryobi 990r trimmer.
3. Removed old spark plug and replaced with a new one.
4. Removed carburetor, took it apart and cleaned it with carburetor cleaner, replaced all carburetor gaskets with new gaskets. Take pictures as carburetor is disassembled to make gasket placement and reassembly easier when you put it back. Also note the hole that the throttle cable is attached to on the throttle link to before you take it off the throttle link.
5. Reassembled outer plastic covers on trimmer with new air filter.
6. Engine starts right up now.
