Check carb adjustment screws. Also may have a blocked muffler. There is a spark arrester screen that becomes blocked. Usually 2 screws hold this in place at muffler exhaust, remove screen and use small tourch to burn it clean.

Engine start to run rough and shot off after 3-4 minutes running

Possible solutions:
You could have water in your gas if so a $3 additive will unfreeze and eliminate this which will cause rough idling. If your carb is clean make sure to let the blower warm up for several minutes, take off the choke as it warms and it will run smoothly. Last if those dont work, adjust your carbs mixture setting screw (when the engine is warm). (and check your oil! Hope this helps.

Hard starting, rough idle when cold, then smooth running when warm

Need year/make/model/mileage of vehicle to provide a more specific set of troubleshooting steps.

When was the last tune up? Hard starts when cold are usually caused by fouled spark plugs, worn plug wires, or weak ignition coils. Fuel systems are not as effected by temperature changes as the ignition components.

How to start the blower friend lost manuel

I am going to presume this is a gas blower.

1. Make sure you have the properly mixed oil and gas in the fuel tank.

2. Put throttle lever setting to choke or start.

3. Press primer bulb 4-5 times, until it gets stiff and feels full.

4. Pull cord until the unit starts or at least sputters.

5. Put the choke lever to the 1/2 way point and pull rope again. Should start. When it has run 30 seconds or so, put choke to the off position.

My Ryobu RYO8554 only runs when it is in the carb lever is in the start position. ANy use of the throttle kills the engine. been that way since I bought it. Thanks Jim

Hi, if you have the lever in start that means the carb is choked. If you are only able to run the engine when the choke is on, then it is starving for fuel. First, make absolutely sure you have the right fuel mixture, then try to start the engine. If the mix is correct, then your carb is out of adjustment. Find the two screws that adjust the high and low idle on the carb. Turn the low idle one quarter turn counter clockwise and try to start the engine again. This adjustment will allow for more fuel to deliver into the cylinder. (adjust more if needed). The high idle may also be out of adjustment, so tune this screw with the throttle on high (and running) until you hear the transition between the high rumbling sound and the high even sound this point is you high idle. Good luck
