RYOBI RBL-30MVA 30cc when pressing the primer bulb to allow petrol thro, nothing happens? and as its not letting the petrol thro, the leaf blower will not start....any suggestions? thanks ben.

Did you check the hose from the fuel tank to the primer bulb circuit? No gasee, no runee.

replace spark plug.if spark plug okay problem could be carburetor or air leak at fuel lines or check primer bulb for crack which cause air leak.any breaks in fuel line or primer bulb cause air leaks fuel system cause carb not get fuel run engine.

Homelite and Ryobi appear to be made by the same manufacturer. Home Depot now carries a "Fuel System Tune-Up Kit, AC04122," that includes 2 replacement fuel lines and a replacement Primer Bulb for 25cc, 30cc, and 26cc 2-cycle engines. Cost is $7 +.

Replace your fuel filter that should do the trick

Sounds like the pickup line for the primer is not far enough into the tank. Most primer lines are only far enough in the tank to work if the fuel tank is completely full. The primer works like a suction, air is pushed into the tank and the expanding bulb draws fuel into itself. A longer primer line can be installed, and most saw or trimmer dealers will carry rolls of it. Let me know if you need anything else or if this helps, Daniel.

who knows. Ryobi should have all tnhis info freely available on their website. National secrets are easier to find (many being on wkikleaks). Perhaps a mole at Ryobi could post??

If your fuel filter is clean, and none of the fuel lines are pinched, then you probably need to replace the diaphragms, gaskets, and screen in the carb. Some carbs with the primer bulbs mounted on the carb have a check valve in the primer system. This is the least likely problem, but it is possible that the check valve is defective.

chnge the plug for the best you can get then depending on the mix petrol oil mix u could cahnge that ie if its 50:1 go down to 40:1 or visa versa if that doesnt work bin it and get a sthil or an ehco

yes,,,,its a dirty carb jet or a blocked carb jet strip the carb and blow out all the running jets,dont go poking wire into any of the jets to clean them this could bistroy the jet/s
