2-cycle newb here...

[Anonymous No.1626650]

I've got this year-old gas leaf blower which was working until 2 weeks ago but won't start anymore. I can't get to the spark plug because everything is cased in plastic, which is held in place with deep T-star bits and I don't have a long, narrow T-star screwdriver.
Anyway my question is, how long should I wait before trying to choke/start it again? The manual says to not pull the crank too many times, but doesn't explain why that is...

[Beppu No.1626660]

>>1626650
Give it 10min a restart the process. If you tried to prime and start it too much, you probably flooded it. Mess with the choke, pull a couple times 100% closed, then 50% closed, then open and see if any luck.

And go spend $7 on a set of torx keys for the future.

Also read up on how to take care of those tools. If you put it away for the winter or aren’t going to use it for awhile, empty the gas out of it. The old gas will gum up the carb and degrade the fuel lines.

When you pump the little primer bulb, is it filling up with fuel like normal? Or are you getting a lot of air? Don’t focus on the spark plug alone, I have never had a small 2-stroke engine not start because of a spark plug alone, it’s always the carb and fuel lines from being stored with fuel.

Ryobi suck. Something to keep in mind when buying tools: You can often get a good one second hand, for the price of a brand new piece of shit. As for your problem, save yourself a lot of heart ache and pay 25 bucks to have a garden tool mechanic to service it.

Floods with gas. Do yourself a favor and go watch a vid about carburetors. Also find out how to drain the gas and do an oil change. Understand how it works and maintain it. Small engines are simple. It needs gas/air crank and spark. My money is on shitty gas or dirty carb if it won't start.

Start it on full choke and hold the throttle while pulling the starter, get it warmed up a bit. Then start it on choke again, hold the throttle and then switch to no choke while still holding the throttle. Had mine for two years and beat the shit out of it, these kind of two stokes can be finnicky and you have to learn the timing of it to impel it to go sometimes.

[Anonymous No.1626741]

>>1626650
I've noticed a lot in california near the ocean choking the engine is not needed unless its particularly cold.

It's an e-z start engine so dont drop start it.

Flick the choke/starter to start, this locks the throttle at a higher idle good for starting it. You dont need to squeeze the throttle or anything just pull on the starter. If it doesnt start after two or three goes then flick it back to run. The throttle is still high from you flicking it to start so give it a couple more pulls.

Also modern gas is cancer. Get ethanol stabilized additive and add it to your two stroke mix.

He's right, I get my tubes clogged all the time and have to replace them because of shitty gas. It can happen fast to but try the easiest stuff to fix it then try the more advanced stuff. Just basic troubleshooting. Good luck, I know how frustrating it can be.

There are some that do both. They don’t work particularly well on either.

>>1627190
No. He wants OP to get a centrifuge and take the oil back out of the gasoline and add it to fresh gasoline.

>>1626901
Why would you change the oil on a 2-stroke chainsaw? Chop down a couple more trees and the bar oil will run out on its own.

I have a weed eater that the little primer bulb won't fill. It will start but at full throttle bogs down and dies. Half throttle is fine.

Must be a fuel flow issue?

dude it needs maintenance.
check the spark arrestor screen. it's probably clogged with carbon. it's the little screen that is on the exhaust port. once it's off spray it with oven cleaner and hit it with a toothbrush after.

[Kevin Van Dam !ZNBx60Gj/k No.1629465]

>>1628079
Check the fuel lines. They degrade over time and get brittle and crack so it will suck up mostly air. You can prime it and get enough fuel in there to start it but as soon as you hit the throttle it starves and dies.

You can find the lines all over, I think even Walmart sells fuel line kits.

[Anonymous No.1630325]

Well I'm convinced it's the carburetor... I tried cleaning the air filter, and noticed that if I soak it in gasoline afterwards, the thing fired up just for 5 seconds or so (burning off that gas).
Not sure what to do from here.

Carb is gummed up fammo.

For some reason that’s the only fucking small engine carb you can’t find on Amazon for $20. They have plenty of other Ryobi replacements, but all I can find is aftermarket gasket and fuel like kits. You can buy a brand new carb for $50 a few places, part number is 308054121.

You can try cleaning it and taking it apart more but I never have luck getting them to run like new after getting clogged with old gas. I just get the new carb.

[Anonymous No.1630554]

>>1630545
That's what I suspected, unfortunately. Looks like you can order it from Ryobi for $37.50 but they probably charge another $12.50 for shipping: https://ryobipower.ordertree.com/catalogsearch/result/?q=308054121
I've never cleaned one of these things, but since I'll have to take it apart anyway, I might give that a shot

Are primer bulbs supposed to empty in these engines or remain full of gas after choking/starting?

[Anonymous No.1630852]

>>1630827
Not that engine but my weed-eater has some fuel in the bulb all the time.
I still have to press it a couple of times before cold start to ensure fuel fills the carb.

[Anonymous No.1631020]

Well I give up. I opened up the carb - it's clean as a whistle. Confirmed the gas(mix) is good, spark plug works fine, fuel lines are good.
What a fucking piece of shit. I could take it to a ryobi service center but I am skeptical they will fix it and honor the warranty.
No more ryobi for me....

Order that kit anon posted here >>1630567

The little jets and bullshit will clog despite everything inside the carb looking clean to the naked eye. That happened to me on the leaf blower, the gad made it look shiny but something was clogged. So you can rebuild the thing with all new parts, or order a new carb. I would suggest the fuel lines too while you’re at it.

And you can blame the tool, but none of those small carburetors will hold up to ethanol fuel sitting in there for months.

If it’s still under warranty, bring it in and they will rebuild the whole carb or put a new one on there.

[Anonymous No.1631111]

>>1631045
This also get all the parts you're not replacing and soak them in carb cleaner in a small closed container over night.

Ethanol gas is really shitty in a lot of different ways. I wish they'd stop subsidizing it.

try holding down the throttle while pulling the string. If you're flooded, it will start after a number of pulls. then let it idle, tap the throttle whenever it feels like it's going to stall. let it run for a minute or two then try full throttle

[Anonymous No.1631945]

OP I’ve worked on these professionally, if you get that carb cleaned and it still doesn’t fire, it’s likely that the rotor/flywheel/magneto/whatever you wanna call it is defective, in that situation you should take it back to Home Depot and have them send it to Ryobi to get fixed probably under warranty. Then when it’s out of the warranty period in a few years toss it in the dumpster and never buy Ryobi again.

>OP I’ve worked on these professionally

>rotor/flywheel/magneto/magneto/whatever you wanna call it is defective

all 3 of these are different things.

a flywheel is there to add weight or for gear reduction

a rotor is a winding around an ironstack or squirrel cage that generates a field when it spins inside of a stator

a magneto spins inside a stator as well but it is like a cup shape and it will have a lobe or some other means of either opening and closing breaker points or signalling a capacitor to discharge at specific times

[Anonymous No.1632121]

starting fluid..give a shot in aircleaner/carb, if fires you know you have fuel issue, if does not fire it is spark issue
