Question about Garden
My ryobi cs30 trimmer will start at full choke, run above normal rpm's just after that, but if i go closer to half choke it dies. im suspecting it's due to a rupture in some diaphgram in the carb that reacts to something to pump fuel into the cylinder, and maybe the richer mixture just after full choke is all that can sustain it until less richer mixture slows down the vibrations and the diaphgram fails?
i am also getting gas leaking out of the carb's air intake. what do i need to do? am i completely wrong about the diaphgram, and just need a new carb? plumb need to replace trimmer? i dont know.

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.

As with all 2 strokes if you have compression and a reasonable spark, you only need fresh fuel with correct oil ratio) and they must go !(as long as you haven't fiddled first and all gaskets are sealing) I start mine by(1) pumping the primer till it is firm,(2) full choke,(3) pull till it kicks ONCE,(4) half choke, pull till it runs,allow to warm up and(5) switch to run (you may need to apply a bit of throttle while pulling as in (4)(or give it a few more pumps if it dies) If all is ok, check that when properly warmed up there is a smooth transition from idle to full revs, if it hesitates it may need the LOW SPEED mixture leaning (clockwise) SLIGHTLY.If it dies the LOW SPEED mixture may need richening(anti-clockwise)(adjust 1/8 turn at a time) Make sure that motor is just peaking at full revs and is on the RICH side of peaking (HIGH SPEED mixture)(this will avoid seizing it Adjust both till it revs cleanly and is JUST rich at full, and idleing nicely and it should start without too much trouble.(If you have fiddled and are lost,-about 2 1/2 turns out from closed on both needles should get you started)

Yes, Your carburetor sounds like it needs cleaned. Or you may possibly need to purchase a carb. kit for your trimmer if the cleaning doesn't do any good. When cleaning the carb. use a Den Tek Brush, (teeth cleaning brush), to clean the small ports. Also, check the small screen in carb. Can get clogged easily.
