My Ryobi 2 cycle weed eater will run when choked, but when the choke is off it dies. Any suggestions?

I would inspect carb and see what the difference is between 1/2 choke and no choke. Set the choke, move the throttle and look into carb- doesnt need to be running. Sounds like something is still restricting airflow at no choke.

chokes are an obstruction placed over the inlet to increase the vacuum in the carby and cannot be pressed
Primer bulbs are used to suck fuel through the diaphragms to expell all of the air in the system to allow starting
normally press the primer bulb until it is full of fuel
apply the choke and pull until it fires
remove the choke and at full throttle pull until it starts

I have a husky 4 cycle I have to choke it and it is a bulgar to start once I get it running it runs like a champ just make sure you check your oil first

This is a tell tale sign of a lean fuel mixture. By choking the unit you are manually creating a richer fuel mixture. I would purchase a compression tester from a local parts store and check compression. If that's ok, I'm willing to bet the problem is still carb related. Two stroke carbs are tricky to clean because of high/low ports that are one way and sometimes impossible to clean. Did you remove high and low needles when cleaning carb? Another trick is to mix seafoam with your gas, then mix two cycle oil to proper ratio. Use 2 ounces seafoam to one gallon of gas, then mix two cycle oil to proper mix. Hope this helps! Good luck and happy wrenching!

You probably need a slight carburetor adjustment. Try to turn the L mixture screw (the one near the bottom of the carburetor on the air filter side, closest to the engine) 1/8 to 1/4 of a turn counterclockwise. These mixture adjustment screws ( L and H) have odd heads on them and conventional tools won't turn them. I use an automotive type plastic wire connector (around 22 gauge) with a ring terminal end which I can hold. Tap the plastic end of the wire terminal connector onto the head of the screw with a small hammer and this will enable you to adjust the L screw. This adjustment will increase you high speed side and possibly allow it to run off choke in a regular manner.

just bought a new Poulan 25cc 2cycle gas power weed eater . I can start it with the choke on but as soon as put on run it dies.

does it blow out alot of blue or dark exhaust? if so adjust screw on carberator as it maybe be running rich, if this doesnt work have the switch checked for malfunctioning

I have the same problem. It will run if I put it halfway between Half Choke and Full Choke. But, just dies if I put it on Run or Half Choke. Don't ever loan your WE to anyone, They might just try to run it on straight gas--That is what happened on another week eater that I had.

you need to replace fuel filter inside the fuel tank . fish it out with and empty tank using a coat hanger and a small hood bent on the end.filters are around $9.00

you need to adjust the carb ,look for small screws around carb turn out 1/4 to 1/2 turn good luck
