RY252CS Ryobi Trimmer - Overview

Pulled trimmer apart, found plastic shims on coil broken. This allowed the coil to drop onto the flywheel, which stopped the crank and in turn sheared the flywheel key. If the key shears it will throw the timing off and the engine will not start. The key is made into the flywheel so it had to be replaced. The trimmer runs again.

It didn't, After 2 new sparkplugs 2 coils iand a fly wheel and coil set using a business card. And is killed switch disconnected? Still no spark and I don't have the clue and I'm amechanic.

I have been using string trimmers for over 40 years now, doing the grounds work at a small motel, and this is the best combination I have found!

I have the new 40V battery carbon fiber shaft model, but I use the curved shaft. I have stacked stone walls and many obstacles to get around, and the curved shaft works best. But, Ryobi sends their straight shaft with the new trimmer, and it turns in the opposite direction (counter clockwise) and is hard for me to get into the areas I need.

To correct this, I use the Oregon brand Gatorhead, which fits on the Ryobi with no modiification (easy) and the line comes in spiral discs which can work for either direction of trimmer head to dispense effortlessly. Now, I have a new curved shaft on a new trimmer with the head turning in the clockwise direction.

This item has been discontinued, so get it when you find one, and stock up on line discs too!
