Hi. Got the above mini tiller with carb noted. Been sitting for years. Got it out, replaced fuel lines and primer bulb & cleaned carb. Bulb will not pull fuel into carb; hooked up right. Runs when gas poured into fuel inlet. Would the fiber flappers be hardened and not allow primer to work? Any other suggestions? Wanted feed back before ordering a kit. Thanks.
Hello sir, my machine will only start when pumping primmer bulb or squirting fluid in the carburetor than stops. the fuel line has broken off, in most small carburetors this is a ongoing problem.old fuel will crystallize when left in tank for a long time.plugging up ports, fuel lines, small screen in carburetor.fuel lines will dissolve clogging carb.this is why it will run when the choke is on creating a vacuum to where there is fuel forced in the carb to rum,also the gas will evaporate leaving the oil behind clogging up carb.the thing to do is remove carb. and clean out,replacing gaskets or fuel line if necessary.use carb cleaner to clean out carb.make sure to make note where fuel line go.the fuel filter broke off of fuel line letting debris get in carb plugging it up.the muffler is known to clog up a lot on these machines where they want run. the compression should be 60 to 120 lbs any thing below 60 is junk. when adjusting the carb screws turn in all the way than turnout 1 1/4 turns turn in slow until machine runs also you need to check for spark by removing plug and grounding against engine to check spark, ok.a new spark plug would be a good ideal too , if you are going to make these repairs use new fuel line and filter,hope this helps,any comments welcome,thank you, !!
A failed check valve in the main nozzle (main jet) will cause symptoms of "no Prime." Not many address that issue, but I have run across it many times doing carb rebuilds and repairs. The diaphragm carbs without main nozzles (usually have only 1 mixture screw) and small ports in the carb ventur); also fail to prime as air backwashes into the metering cavity when the primer/purge bulb is released. Failed check valve is the case. As a shade tree mechanic, I personally am trying to find a FIX for these failed check valves as they render the carb useless.

Here is a link to parts listings, when searching put in the work Cultivator and it gives you a few options. Hopefully the pictures will let you decide which one is yours.

The primer pulls fuel through the carbruetor
So take your return line from the carb. and hook it to the inlet side of the primer and the other side
of the primer bulb transtions into the fuel tank.
You know when you have hooked it up right when you press the primer it fills with fuel and dumps back into the tank.

Thanks for all your great replies. Really appreciate the time you all took to comment. I found the problem. The needle valve was "re-sticking" randomly after cleaning. It would fork for a few minutes and then stop working again, which was what was befuddling me. I soaked the darn thing over night and used a variety of cleaning fluids on the seat with some mild "scrubbing" with a plastic tube. After around 20 years of sitting, I guess it was REALLY gummed up, LOL. Don't remember the last time I used it or why I stopped using it.
I am designing a new herb garden and have some landscaping issues that are too tight for my Troy Bilt; I got to wondering if there was any way to get that old Ryobi running cause it would be perfect for these projects. After a couple of days, it is still starting and running; and digs like a badger. Neat little tool.
Thanks again for your help, everyone.
