What seems to be the problem with the Ryobi C430 string trimmer�s throttle? I have not seen much quality in the low end cost trimmers (Toys) vs semi or commercial grades. I have been sold on the 200.00+ Echos that are not split shaft, straight and 2-cycle vs 4.

Working with mechanical tools/machines and investing in them, I have not found many multi-purpose tools/machines that would do all the jobs well. I basically stay away from tools and machinery that I have not seen and proven to work (a few years). Great Ideas But Toys IMO! This causes me to have more tools but satisfaction with them.

Could be the Ethanol in the gas you are using!
It's causing problems with all these small engines.
Do a Goolge search for Ethanol and small engines.

I took Throttle Problems to be a mechanical issue due to "poor design". I agree with, "Could be the Ethanol" if it is not weekly used equipment with Stabil treated fuel or Etc. We need to hear the problem from Jerry.

It's a poor setting in order to meet epa standards. One just needs to cut slots in the mixture screw heads so you can adjust them with a screw driver (or buy the super-secret pacman driver), just like the carbs in classic cars. And absolutely don't use Ethanol.
