Primer Bulb won't prime or fill with gas, how to fix. (purge bulb)

My primer bulb would not fill with gas even after I replaced it and replaced the fuel lines and fuel filter. This video shows how I fixed it. Was just a stubborn clog in the return to tank port that took more than a blast of carb cleaner to clear.

Short and sweet and directly to the point! Very refreshing! Keep making more videos like that!

[@ironmanxrp4980]

Exactly 💯

[@jimholmes964]

Going through this at the moment. Yeah, mine's not clogged, but WILL NOT draw fuel into the bulb. Bought an after-market carb, new fuel lines/tank grommets, new fuel filter. Absolutely tearing my hair out! Jim, Australia.

Did the aftermarket carburetor work? I'm having the same problem. I took the carburetor apart. Also cleaned that area inside where primer bulb goes and I think carburetor fluid is just went through that nozzle. I'm hoping priming works now but also interested in probably buying an aftermarket carburetor.

Bought this for my small back deck in the Eastern Sierra. kzbin.infoUgkxoHYZbq5g9fkcAtinlTqstNlje-UQkCHN We get A LOT of HEAVY snow so I was a bit skeptical but it was worth it! After the first storm of the year this has exceeded expectations! It throws snow very well, even 10-12” + that said the more it piles up the harder it is to maneuver the machine. It is exceptionally light weight and overall exactly what I was looking for. If you have a large amount of snow and a lot of area to clear, you may consider something with a drive engine to help maneuverability, but for decks, second stories, roofs etc, you can’t beat the light weight to great snow throwing ratio. Side note, the chute rotator is a bit flimsy and it initially didn’t seem to work, after a few uses it seems to have loosened up.

That looks like a Weedeater brand blower. I have the same one, or a very similar one, and that thing has been VERY good to me. Original carb, original diaphragm, original everything. I don't ever remember changing even the primer bulb. Recently the return line broke right at the tank, so I replaced both fuel lines. It's kinda crazy to think that I bought it back in like 2005. It's performed like an absolute champ. It was dirt cheap, too.

Ya someone gave it to me non running, happy to have it around, very simple, not much to go wrong with it.

[@markamberg8362]

Thanks. I think I have the exact same problem and I am soaking mine in a small cup of carb cleaner over night. Wish me luck. 😅

[@ironmanxrp4980]

I have the same issue found this vid and im sure this is the answer. Thanks

[@jsimm4587]

That’s a small check valve don’t poke it with a wire . It should open one way and close the other. It should close while the bulb expands after pushing drawing fuel threw the other hole pushing blows the fuel out and back into the tank closing the carburetor side .

[@am932]

I tried cleaning with a wire from a bike shift cable but couldnt get it cleaned up, thanks for the info

[@JacobAHull-nx6rx]

Man this was it. But I still can't get er to rev up right. Thanks

[@mojamski]

Great info thanks. I had the exact same issue hopefully this will solve it

[@spencerwoods1023]

Update?

[@namastezen3300]

Thank you. All the best regards to you 🙏

[@Luciano-jg5ws]

It can be other things, I solved it by lifting the metering lever.

[@emersoncampbell2661]

Thanks, I will try your methog.

[@lisanash258]

Would you be able to answer a question I have, I recently brought a petrol strimmer from SGS engineering and I had to return as the unit was too heavy for me to use. When SGS received the item back after I confirmed I did not use it try to, they are saying as there was fuel in the priming bulb they can not expect my return as they are saying I put fuel in it, and attempted to start it, which I did not. My question is would there still be fuel in this bulb left over from SGS testing this unit as surely they would have tested it. I would really appreciate your thoughts why there is fuel in the priming bulb. Many thanks.

[@RepairNut]

@@lisanash258 your guess is as good as mine. Someone could have tested it during manufacturing, or maybe someone else returned it already before you purchased it.

[@irvingguerrero7303]

short and sweet. Like it.

[@Raysmusicchannel]

Thank you brother wow

[@user-ms6rm1fc9x]

Suck or soak it?? Im confused

[@oldguy8177able]

hi,biggest mistake because i have done it is the tubes to gas tank have be seated properly,if not the petrol tank can not hold perssure,nothing will work,like me you will look every where else but there good luck

[@ocam988able]

Thank you

[@rickwright4852]

I’m not sure how it was working because there’s a check valve in the fuel line fitting. Fuel is not supposed to go through it. That is a return port and fuel or air goes back into the fuel tank from it.

[@RepairNut]

Mine I don't think has a check valve, those are just cheap brass fittings, but not sure. But the bottom fitting pulls from the tank, and the top one is where the fuel returns to the tank. I suppose it is really a Purge bulb and not really a primer bulb, just pulls new gas into the carb and purges what is in the bulb back to tank.

[@hedger48]

Yes, isn’t that supposed to be one way? Out of the carb and into the tank?

[@RepairNut]

@@hedger48 Yup.

[@tomt9543]

@@RepairNut the round silver plug with the hole in it is indeed a check valve, and if you could pass carb spray, air etc. from the brass pipe and out the hole, then the check is blown out! If you watch Walbro’s KZbin videos on rebuilding these things, they warn against blowing anything including carb spray through any orifice in these little carbs because these valves are just a tiny disc of paper thin rubber, and cannot stand pressure or probing with a pin, wire, torch tip cleaner etc! Some of the Walbro brand checks are replaceable, typically the brass ones, but some others are not, and most other brands don’t have replaceable ones at all! So blowing out or piercing one would require ordering a new part of the carb that it’s mounted in, or trashing the carb! Most 2 cycle carbs have at least one, some have more. I can’t believe you got this thing to run like that! You should go buy a lottery ticket!! Ha!

[@RepairNut]

@@tomt9543 well it is still running!! It wouldn't blow through that port either direction so must've been blocked somehow.......

[@danielbyrne1899]

Good one ! Thanks

[@charlesoverton]

Thanks

[@rocknral]

Here is a strange one. Ive cleaned a Zama carby. Cleaned the check valve. New bulb, lines on correctly. Will not pull up fuel. Disassembled carby to check multiple times. Still wont prime. Spray with ether to start and runs, idles, and response like a champion. But srill no fuel in bulb??? What the hell is going on here?

[@javierserranoyoutube]

Something else that comes to mind is that when I pump the primer bulb, it does not return to its original position. This may be your indication that you have this issue. I am going to try cleaning that part you show here and see if it solves my issue. Thank you.

[@javierserranoyoutube]

The other thing I noticed on mine was that the line connected to the primer bulb was not long enough, reason why it was not sucking gas. I cleaned the part you show in the video regardless. My trimmer started but did not stay on for long. I am moving now to replacing its gas filter.

[@AldousHuxley7]

Concise! Thanks

[@austinhinkson1414]

👍🏼

[@mrsdavis85]

Pull string will not work on my echo hedge trimmer

[@roseymalino9855]

If you mean the cord is stuck and does not withdraw when pulled, check for cord having slipped off reel and being jammed between reel and case.
