My ryobi cs30 gas trimmer (3 years old) has been difficult to start this year, has been getting worse all year and now wont start. What's up?

Dirt or varnish in fuel filter or carburator. Change filter if there is one.

Flush out the carb with a varnish remover.

Open high speed needle valve 1/8 turn farther, then turn in while running until it just smooths out.

how do I repair/replace the pull cord on my Ryobi CS30?

50:1

Is the fuel old or has it been drained and refilled?? Sometimes old fuel will do this. Also make sure the air filter is clean and free of oil/dirt as this will also hinder the starting.

The primer button also is something to check. Push it 7 times, full choke, pull for 5 times, turn to half choke, and the unit should start.

Let me know,

Chip

No trick - sounds like it is stuck!
Can you take it back?

If no - well - keep trying :(

Are you taking if off to put on other head attachment?

Mine says 50:1 on the gas cap. It's a 2006 CS30. Model #RY30120.
2.6 oz of 2cycle oil to i gallon of 89 octane fuel is what i use and have no problems

If you still don't have a spark with the new plug, then you may have a kill switch wire grounding the motor, keeping it from starting. If it's not that, then you have a bad ignition module (coil).

what model is trimmer? cs30? if you found the line on it clockwise, that's your problem. on the cs30 it rotates counterclockwise if youre looking at the head while trimmer is upside down. the line has to be wound opposite direction or your going to have a MESS of string in the head.

what do you do when there is no spark??????????????????
how do you fix???????????

try removing the starter housing, inside will be a large white or black wheel, visually inspect to make sure the componets are not damaged and that nothing jamming it. try using a lithium spray grease to lubricate the componets. if it still doesn't work the inner coil is probably damaged or came off track. it is very difficult to fix or replace this coil. i suggest taking to your nearest service center but if you would like to try it yourself, let me know and i will give you further instructions.
