I have a Ryobi blower / vac approximately 3 years old which was working fine one day and will not start since. I replaced the spark plug and check to make sure all connections were fine. when starting it seems that it is not getting either a spark or fuel is not getting to the motor.
Check the spark gap
Back to basics, remove the spark plug, lay on its side against a metal part of the machine ( away from the plug hole ) crank the engine, do you have a spark at the plug? if yes then we more that likely have a fuel issue, if no spark the ignition unit is bad ( make sure the switch is on ) if you have a spark re fit the plug, crank the engine with the choke on, remove the plug again is the tip wet? if no there is no fuel to the engine, remove the fuel filter from inside the fuel tank and replace with new, try again, if still no fuel to the plug a carb strip and clean will be required, for the time it takes it is well worth removing the muffler and check the condition of the piston face through the open port, any signs of scuffing and the machine has seized and will require further investigation.

take off the fuel filter and see if that works . if it runs then it needs a new fuel filter. keep me posted

Line from tank with the filter on it is the supply line and goes to the carb inlet fitting. This is typically on the "bottom" of the carb (with the tank being up) and will usually have a fitting with barbs or a bulge on it to ensure a tight fit. The other fitting on the carb is the return line and is usually a straight tube fitting with no barbs. That line goes the suction side of the primer bulb. The third line goes from the outlet of the primer bulb to the return barb fitting in the bottom of the tank. Fittings have to be removed from tank to properly install the new hoses on them. Remove retainer ring on outide of tank and push fittings into tank, then shake out of the fill opening. More details on replacing hoses are listed in another post about Repairing Ryobi trimmer.
To leemineres, if hoses are on right and unit still stalls after starting initially you probably need to disassemble carb and clean out using spray carb cleaner. May be sticky needle valve, or partially plugged port or jet.Could also be hole in diaphragm. Gasket and diaphragm kit would be good to add when you take apart, even if diaphragm does not have a hole.

Hi,
You can download the manual at www.managemyhome.com. I have the Ryobi 720r and the sparkplug is a champion RDJ7Y.
Good luck!

Starting problems with 2-cycle engines are usually traced to fuel line/filter clogging due to jelling of the fuel mixture while the engine is idle. Best fix is fuel mix pretreatment with some kind of gas saver in the gas can. Marine grade additives are the best, such as 2+4 gas treatment. Now your stuck with pulling the fuel lines and blowing them clean. If the carb has a primer bulb, you can sometimes force the fuel through, but a complete cleaning is in order. Pulling the plug and putting a few drops of fuel mix directly into the cylinder head, (or in the air intake), can sometimes get the motor to fire. This proofs the problem as being fuel starvation.

No spark what would cause this?
