Hello I have a Ryobi HT26 hedge trimmer that is one year old. It starts fine but dies after I try to release the choke and pull the throttle. I cleaned the air intake that was semi plugged, replaced the spark plug and changed the fuel. I also checked for binding on the trimmmer blades. Any ideas?

Standard plug gap for most chainsaw, trimmers and hedge trimmers is 0.5mm

full choke on , push petrol bubble 5 times then pull starter cord., with luck it will kick in to life after a 20/30 secs put on half choke , run again for 30 secs the no ckoke.

The main problem with Ryobi products is that they flood very very easly. So the more time you try and pump petrol into the carb the more it will flood . If that happenes then choke off and switch off and then just pull starter cord for about 30 secs then switch on and it could start if not prime it again as above good luck

If you remove the air filter you should see the choke butterfly valve on the air intake to the carburettor.
The choke lever should be connected to the axle of this valve on the outside of the carburettor.

• Alow the engine to run for longer on the start setting before you switch to run

• Ensure air filter is clean. Foam elements can be washed with hot water and detergent. Paper elements can be cleaned with compressed air blown from the inside of the filter but ideally should be replaced.

• Check fuel lines aren't kinked or blocked restricting fuel flow.

• Ensure fuel filter isn't dirty. This is probably located at the end of the fuel line in the tank.

• The fuel lines may have become airlocked.This can happen if the tank is run dry. If the trimmer has a primer bulb, alternatively press it several times and then try to pull start the engine with choke on. Repeat this several times. The primer bulb should feel spongy and fill with fuel.Once the engine kicks, switch to run.
  

its probabley your throttle cable , try pulling the throttle full on when you starting up the trimmer word of warning though only do this on a very flat surface..

The fuel line probably has become air locked .Keep pressing the primer bulb if the trimmer has one and also repeatedly try to pull start the machine with the choke on. Eventually the air should be flushed from the line.

My Ryobi 890r brush cutter will start and then die

you need to adjust the high speed needle turn it out in 1/4 increments as you throttle it, low speed may have to come out alittle but do high speed first. I had to answer this as I use to have a pastor john in sturgeon bay, miss him alot.

could be the coil

purchased new unit
