20 Most Recent Ryobi Blower Vac 205mph Leaf Blower Or Vacuum Gas Powered Gasoline Zr08510 Questions & Answers


Hi Paul:
I'd start by pulling the spark plug, attaching it to the lead, then spin it over and check for spark.
This will probably be a 2 cycle motor (Check to confirm) so make sure your fuel is mixed correctly.

This happened on my older Ryobi as well. Turns out it was the fuel lines. The ethnol in the gas made the lines swell up inside.

The primer does not necessarily need to work for the unit to run. It does have a choke to aid cold starts. However it is a good indication of something wrong in the fuel system. A primer bulb that does not return to shape or does so slowly indicates a clogged screen in the carb. Check the fuel filter and fuel lines. Replace the fuel lines if they are stiff or discolored, rebuild the carb and replace primer bulb.

Not sure if your model has two throttles or one. It should have a trigger and a thumb lever. Be sure the thumb lever is closed. if that is not the problem your mixer might be to rich. it says 50:1, but use 40:1 and see if that helps

Without more information, the best guess is that the piston is probably seized in the cylinder, this will not fix itself by adding oil now. It likely needs a new piston and/or rings and/or cylinder or shortblock assembly. You can google your model number for sources of repair parts. Depends what you find when you disassemble it, if you can get the piston out you may be lucky to get by with a new set of rings and honing the cylinder.
But it will be a batch of work for a $200 blower. May be worth it if you can do it yourself and the parts arent too much. Certainly a shop couldn't do it for less than the replacement price of the whole blower.

FLYWHEEL REMOVAL:

Use long-nosed pliers to remove the washer from the shaft.

While applying steady upward pressure to the flywheel, firmly strike the end of the shaft with a rubber mallet until the flywheel breaks free. Several blows from the mallet may be necessary to free the flywheel from the engine assembly.

Stating the obvious it is running too lean on the mixture screws, you may well need a special tool to do this, but you need to open ( anti clockwise ) the H screw on the carb about 10 minutes on a clock face, this will richen the mixture and aid acceleration.

Sounds like a fuel problem - have you tried using partial choke? At least, this might verify that you just have a fuel problem. The 4-stroke is not as temporemental as the 2-stroke, but worth checking a few simple things : Is there an obstruction in the fuel supply ? Is the fuel tank supposed to be vented - if so, is the vent blocked ? Is there some dirt in the fuel, leading to a blocked jet in the carburetor ? - if so, drain/empty the carburetor, clean sediment & ensure all jets are clear and refill whole system with clean fresh fuel : If the carburetor or any part of it is loose, there might well be an Induction air-leak ( which could impair the engine's intake of fuel ) : And (of course ) - Is the spark-plug badly "gapped" or fouled ? Try to isolate and eradicate in a methodical way, good luck !

This is just the return to tank pipe, it does not need to be in the fuel, just in the tank far enough not to leak out the top.
