Put in new carb parts, cleaned all carb circuits, runs only a little better than before...when adjusting carb, has limits on how far you can turn it, just starts to run a little better when limited out. is there a way to reset the limits?
I have a RYobi SS30 and it will not run at all. I have pulled the cord about a hundred times, yes after about 10 I should have gotten the picture, but if anyone knows what to do to correct this I would appreciate this. I am not very mechanically inclined so any help would be appreciated

If your fuel filter is clean, and none of the fuel lines are pinched, then you probably need to replace the diaphragms, gaskets, and screen in the carb. Some carbs with the primer bulbs mounted on the carb have a check valve in the primer system. This is the least likely problem, but it is possible that the check valve is defective.
line runs from little filter in tank to carb. line from carb. to primer bulb line from primre bulb back to gas tank. lines are 2 sizes need to cut at angle end of lines in tank so you can get them thru holes and grab with needle nose plyers and pull them thru. make sure you put the little filter on end before you pull line thru and leave enough so filter can move around the whole tank. second line in tank is smaller and need to cut and pull it thru hole in tank to primer bulb
Sounds like you need to adjust the carb. Remove the caps from the carb. Turn both screws clockwise until all the way seated. Start the trimmer and while running begin to back out the screws slowly until the trimmer is running strong but is smooth. Once you have the carb adjusted you can put the caps back on or you can discard.
Try getting some carb and choke cleaner and spraying down the carb. You might have some varnish in the carb and it won't let the fuel flow properly. My ryobi 4 cycle trimmer does that every year. I clean the carb and it usually runs decently. Good luck roundo4
You should have 2 small adjuster screws next to each other on top of the carb.Try adjusting each of them a little with a thin screwdriver as the engine is running.Put strimmer on the ground first and adjust screws while you are revving engine until it runs correctly.Trial and error and very small adjustments can make quite a difference.Hope this helps.
check for restricted exhaust next
some manufactuers put screens in their exhausts and they tend to plug up sometimes remove clean and put back screen.
When you removed carb. and dimantled were the rubber pieces soft and pliable? if they were not then consider a carb. kit
Be sure on the needle valve side of the carb. the diaphram side
the gasket goes first then the diaphram not the opposite. Zama or walbro the same deal
sometimes you have to dismantle the carb totally and drop it in carb. cleaner for awhile to allow to penetrate where its hard to clean and sometimes you have to replace the carb,but not always
the initial carb. setting for high and low is 1and1/4 turn and tweek from there.
Also the smallest pinhole in the fuel lines will create havoc also.
and if compression is weak or low the carb. will not work properly either.
Try these things and maybe it will help you some?
I don't mean to over simplify this, but are you using fresh gas? Gas string trimmers are extremely ticky when it comes to gas. They like it SUPER fresh. And while the gas and oil mixture should be right, it can be off a little bit and still run. Try draining all of the gas out, and then filling up with fresh mix. This is ALWAYS my first step with string trimmers, and it fixes the problem 75% of the time.
Hope this helps!!
Many times with a gas mix, after sitting for a while, the mix separates and gums up the carb. Taking the carb off and soaking it overnight in a parts or carb cleaner and running carb cleaner through the tank and gas lines will cure this.
