Great video. I failed to take enough pics when taking mine apart and missed some details about gasket order. This video was a lifesaver!
thanks friend. glad I found this. I didn't realise the kit covered so many carburetors and might have used a slightly different fuel pump diaphragm first time I tried and the saw wouldn't idle. After watching your guide, I took the adjustment high/low screws out for cleaning and whilst there filed slots into them so I can now make adjustments with a flathead screwdriver, because I don't have the special tool. All round awesome.
Thank You - great video and explanation of the parts. I used this to rebuild the carb in my craftsman chainsaw. I found the screen was plugged and causing the saw to bog down when hitting the throttle.
Thank you for the tutorial! My Stihl 026 chainsaw has a Walbro wt-194 carb. It's very similar to the one in your saw. I'm guessing that's an old Craftsman saw, from back when Sears/Craftsman equipment was at the top of the food chain on their power tools....
After doing the carb rebuild, empty the tank. And add fresh ethanol free fuel, a new fuel filter, and clean out the fuel tank vent. Then cross your fingers and start her up....
Great video i just picked up an old Craftsman leaf blower for the spring. Previous owner said he had a hard time starting it. This will help alot!
just rebuild my carb, thanks for the help, worked like a charm
Thank you for posting.
Excellent video - just helped me rebuild a WA-146 :)
Used to repair a Husqvarna 136 chainsaw carburetor. thanks for energies spent to make this video.
Great video and I'll be using it when I rebuild my WT carb. Thank you
1 of the best vids yet lol. Ty!
Hey man, thanks for the vid; this is helping me greatly!
He got the spring and needle in on the first try. Took me about 30 mins.
Excellent quality video and advice. Thank you.
2 1/3 turn for Low side. I use this setting to get started and then fine tune
Very well presented thank you
Did you post a video about the welsh plugs? Can't find it.
Is the end of the needle valve lever that is fork shape suppose to touch the top of needle valve when its level . Mine has touching the bottom of the needle when level
Nice tuto!! Have you something about the RCGF walbro style carburetor?
Perfect video, very helpful, thank you!
Bravo - my primer has lots of air bubble so does fuel line .. I must have a hole in fuel line .
what about @ 7:09 the brass screen check valve cleaning or replacement ? regards
My saw starts up goes right to high races to high speed . Will not idle . It is a new carb . Could be carb if so what a good name . WALBRO carb good 1 to order?
valuable, thank you...
So is there any need for me to remove the Welch plugs. My chainsaw dies when I go to accelerate it after starting
thank you but i would like to see how you can change the cercle metal?
Perfect, thanks for posting ;) good job
my fuel can't get out from the tank, I shot air by the line and air n fuel got out from cap ! Do the tank is not plugged and diaphragms seems to work ok on carb so why I Can't get fuel ??
What dya think guys ?
Hello, where did you get the little damping tool you used on the screen?
My motor cuts off at idle, runs rough at mid throttle but sounds pretty good at full power. It's also blowing more smoke than normal. Hoping this rebuild will fix the problem!
Thanks
Fajne rozwiązanie i dobrze opisane
In my tries of getting this blower to run, I found out the L screw is totally missing. I think that is why the blower won't stay running. Do you think that is the problem.Larry Starnes
Great thanks. Interestingly another guy on YT working on a similar carb (model aircraft) says to seat the diaphragm with the 5 hole disc plate side outwards?...wt..
Thank you, your video helped!)
I own a Poulan blower/vac which has a Walbro carburetor. I cleaned it but sometimes the engine will stall while idling and if I pull the trigger. What should I do about that?
Have you adjusted the low speed screw? Sounds like your low speed mixture is off
I spend over $16 on a Walbro rebuild kit and check valve. The carb continues to fill the crankcase of my saw with fuel even with both of the adjustment needles turned all the way in. The internal check valves can go bad. They aren't easily serviceable and are not included in the rebuild kit. The metering needle seat can also wear out and isn't replaceable. If you disassemble the carb and find any bad gaskets or diaphrams you're better off saving your time, money & aggravation by scrapping it and buying a new carb. If the gaskets and diaphrams are good, clean the carb, try it again on the saw & pitch it if it doesn't work.
That is good unless you are looking for a carb. that is no longer available.
Brand new husqvarna brush cutter 345FR 800$ and the POS carb floods the machine. I turned the screws in all the way and still floods. Its spotting a ton of gas out. I bought a new carb, but want to fix the broken (new original). What could it be?
@@bradspaugh9827 There is certainly more than one reason a diaphragm carb can flood. If you go onto the ZAMA website, there is a troubleshooting list in their tech guide that lists all the possible causes. A common one is a small bit of trash holding the fuel needle open constantly or the metering lever diaphragm has been installed wrong in the carburetor.
Could you post the complete list of walbro carburetors that KT-10WAT works on please.? Thanks
he showed the full list
Grrr! Metering diaphragm and fuel pump good. I'd say some jelly from water and untreated fuel. I have done thousands of these wt's, not to mention every single other brand small engine carburetor that has probably ever existed. From pulse to double barrel v twins to very rare anymore Tecumseh v twins with the dual plastic carbs. And I'm not talking bowl replacement kits, 3 componants ever really needed for dem. Love mikunis though, best carbs out there. Old bowl style Tecumseh is the most difficult. IF you really can properly do an old bowl Tecumseh, not the ones with the emulsion tube o rings either, that is when carburetor madness sets in.
I agree 100%!
I've got an old Craftsman commercial walk behind edger with a Tecumseh 3.5hp motor. My dad let it sit with gas with ethanol in it for 2yrs. (Yes, he did) The bowl was all rusted out. So I tried to find a new carb, and they dont make them anymore. So I ordered a Chinese fleabay carb, and the throttle and choke are in a different orientation. Grrrr!
So I tried using the new fleabay carb parts to rebuild the Tecumseh carb. Craziest carb I've ever worked on!!! And, of course that idea was a no go... So, I'm going to try and rig up the choke and throttle with a paper clip to the fleabay carb. If that doesn't do the trick, she's heading to the dump...
1 1/3 turn for HS, good to know after my carb stopped I lost track for stock setting
What is the stock setting for low speed?
I just realized you posted the low speed in another comment. Duh lol
Thanx bruh.
I got a never started brand spanking new Walbro wt-688 that floods cylinder in Al-ok 54cc.
Not sure this vid helps but I learned that I’m screwed.
Maybe youre hoses are inverted
I just watched your video and rebuilt my carburetor. I am having problems with getting my blower to run. It starts using starting fluid and runs like 20 seconds and then dies. Do you have any ideal what the problem is. To me, it doesn't seem like its getting fuel but I have no ideal why. Looking at the fuel line, it doesn't seem like it is a solid line of fuel going to the carburetor. It looks like it has breaks in it .Any suggestions what the problem is? Thanks in advance
did you resolve? Maybe the L screw to adjust
I took this exact same carburetor on a brush cutter the only difference is mine works with a pulse line
Those Hi Lo adjusting screws on my carb have a tamper proof component fixed. so cant give it a thorough clean. Might just have to bin it.
John Small you should be able to pry the caps off.
You can cut them off. They are nylon. Once they are off, you can properly adjust your Factory-set LEAN carburetor to run the way you want.
Never spray carb/choke cleaner spray into those circuits. It can ruin the carburetor.
@@roycagle3646 how? Its a chunk of metal?,
Looking for a new wt324
What happens if the hole on the cap is facing the H & L screws instead of the opposite?
nothing, placement on the pump cover plate isn't a big deal. it's just there to allow a relief when the pump pulses.
That is an atmospheric vent hole and should be facing away from the engine.
Pop off pressure spec?
what causes the gas to run out of carb
A leaky seal
Bad breather on the tank can do that. Temp warms up and pressure builds.
I don't think it matters which way the little vent hole is facing.
Ihave to keep pushing my primer button to keep the auger running what could be wrong with it
Tip: The primer bulb does NOT push fuel into the engine at all. It pulls fresh fuel from the fuel tank into the carburetor and pushed old fuel and air in the carb BACK into the fuel tank. This is true whether the bulb is mounted on top of the carburetor or not on these diaphragm carbs.
The carb isn't pumping fuel or it could be dirty in the screen inside the carb rebuild kits are cheap and it's not hard to take it apart and clean it up just don't hit the diaphragms with carb cleaner it will dry them up
@@prospectingwithdisabilitie8288 dont spray carb cleaner onto plastic or rubber parts as it can danage them too.
My kit came with three gaskets. One blue, one black, and one beige and textured like yours. What is the difference besides the holes?
Those are not true gaskets. They are actually the fuel pump diaphragms for these carbs. The blue one is made of mylar...like a drum head. The beige one is made of teflon. The black textured one could be made of butyl rubber and will pump the most fuel.
Should I use the blue one I put old one back in it the one with white and crossed
How do you clean the muffler ?
Bruce. Try caustic soda -- as long as ther is no aluminium of course.
Remove it and cook it in a fire.
Nice well filmed vid, a little slow for my tast, but ok. One thing to point out: If You pull out the little filter: Never reinstall! Allways replace with a new. It is superdelicate and tampering with it will most certainly cause You grief.Reinstalling it with a drift, backside of a drillbit is useable as "Donyboy73 points out.

Why did my weed eater muffler fill up with gas???????
Take your muffler off and take out your plug look in the exhaust port on the cylinder move your piston by pulling the starter rope slowly and look for scoring or scratches on the piston you're rings could be toast another thing it can be is if you have your fuel lines on backwards it can flood out your engine but my guess is that the piston or rings are the problem
Thanks Chris
I think you need glasses. It's WT991
Why does the manual say for starts to bring out both the low and high valve pins about 1 to 1-1/2 turns? Both mine were 1-1/2 turns yet you have it set high side at 1-1/3 turns and the low side at 2-1/3 sides. Shouldn't they both be about the same?
That means mine is running richer at idle. i could reduce the low side turns and lower the idle RPM.
Normally, they are about the same, but do NOT have to be. Many folks tweak their carbs to accelerate more quickly and/or not overspeed at high rpm.
You sound like John malkovich
Be careful using carburetor cleaner spray on these small diaphragm carbs. Strong solvents can and will swell up the check valves that you do not see in the Low and High speed circuits; rendering the carb useless. It also can affect the check valve in the brass main nozzle of the carburetor, again making the carb useless. Your best bet is to NOT use any strong solvents on these when stripping and cleaning them. I like to use WD-40 to float away dirt and loose debris.
Same goes for blasting with high pressure air. The check valves can be damaged. On some, they'll blow out of the carb body and be gone forever.
Been there, done that.
@@bartprice3439 Yes indeed they can sir! Great point!
doing good until the ads popped up and blocked the view.
all that fondling the carb does nothing for a viewer. get to the point.
