How to fix a Ryobi Trimmer that won't start?
- J
  John ChandlerJul 30, 2025
  If your Ryobi Trimmer engine won't start, several factors could be the reason. First, ensure the On/Off Stop Control is in the ON position. Next, check the fuel tank and fill it with fresh fuel if empty or contains old fuel. Also, make sure you press the primer bulb fully and slowly 10 times. A fouled spark plug or a plugged spark arrestor can also prevent starting; in this case, replace or clean the spark plug and clean or replace the spark arrestor.

How do I fix a Ryobi 890r Trimmer cutting attachment that won't advance?

  If the cutting attachment on your Ryobi Trimmer won't advance, there are several things to check: * First, stop the engine and clean the cutting attachment if it's bound with grass. * If the cutting attachment is out of line, refill it with a new line. * Check if the inner reel is bound up and replace it if necessary. * Also, ensure the cutting head is clean by cleaning the inner reel and outer spool. Other potential issues include a line welded (disassemble, remove the welded section, and rewind), a line twisted when refilled (disassemble and rewind the line), or not enough line exposed (push the bump knob and pull out the line until 4 inches are outside of the cutting attachment).

  If the cutting line on your Ryobi Trimmer advances uncontrollably, it's likely due to oil, cleaner, or lubricant being present in the cutting head. To resolve this, clean and thoroughly dry the cutting head.

Why does my Ryobi Trimmer engine lack power or stall when cutting?
- K
  Kelli ThompsonAug 14, 2025
  Your Ryobi Trimmer might lack power or stall while cutting due to several reasons. Old fuel is a common cause, so drain the gas tank and add fresh fuel. A fouled spark plug could also be the culprit; try replacing or cleaning it. Additionally, a plugged spark arrestor can restrict engine performance, so clean or replace it. If these steps don't resolve the issue, the carburetor may need adjustment by an authorized service dealer.

What to do if my Ryobi 890r Trimmer engine will not accelerate?
- M
  Michael GallagherAug 19, 2025
  If your Ryobi Trimmer engine won't accelerate, consider these potential causes: old fuel, which requires draining the gas tank and adding fresh fuel; a dirty air filter, so clean or replace it; or a plugged spark arrestor, which should be cleaned or replaced. Also, stop the engine and clean the cutting attachment if it's bound with grass. If the problem persists, the carburetor may need adjustment by an authorized service dealer.

Why won't my Ryobi Trimmer engine idle?
- R
  Renee SmithAug 25, 2025
  If your Ryobi Trimmer engine won't idle, it could be due to a few reasons. The air filter might be plugged, so try replacing or cleaning it. Another common cause is old fuel; in this case, drain the gas tank and add fresh fuel. If neither of these solutions works, the carburetor may need adjustment.
