Question about Ryobi Garden
I have a Ryobi (RY10521) C4620 Chainsaw and it doesn't want to start up. It has lots of spark, the chain guard is pulled all the way back, and its getting plenty of fuel. I do believe its getting to much fuel. When I pull the pull the spark plugs it fully saturated. So do I adjust the L rpm jet but if so how do I adjust them? My H L rpms jets do not have the limiter caps. Should there be limiter adjusters caps on there but so that someone can adjust them? Since I dont have the caps, there are no red or yellow plastic caps to adjust, how do I adjust them? All that's there is a metal round nub with a notch that remains, no philip nor flat bladed screwdriver can be used.

If plastic cap is present, it should just pop off with a thin sharp hook. Look carefully at the screw heads--they may be 'D' heads which require a special screwdriver and are supposed to keep owners from moving the screws (thank the EPA for these). Only authorized saw servicing dealers have access to these tools and therefore are the only folks allowed to adjust these saws. Being nonconformist, I made my own by drilling the center of a 1/4" rod, sawed off one side somewhat and welded a flat across the cut. Hope this helps!

It does sound like its to lean.They come from the factory to lean to start with usually.You need a special wrench to adjust it.I bought mine from ereplacementpartsonline.I think it was about 7 or 8 bucks?They fit a lot of different saws and weedeaters.You may need to open both screws up just a little?Mine was one and half turns out from a very lite seat.If you screw in it do not tighten it.Just till you feel it stop.Then just bring it back out a turn and a half.Should be very close.
