Walbro Carburetor welch plug removal for deep clean.You can do this

There was a time when doing the deep clean on a carb scared the hell out of me. I noticed that I was amassing a large number of welch plugs. As usual I looked to KZbin for how to remove them. Using a vice and a towel just didnt appeal to me. Using the self centering punch worked fast and easy. It hasnt failed me yet and the scary old vice is out of the equation. All is good and I hope this helps someone.

[@nigelcarren]

Hey Dave, thank you... what a gent you are. You know, I have nursed rally cars across the Sahara in my past and fixed some really complex machines, but this little carb has had me scratching my head. I was about to lose the plot when I noticed this little plug in my new gasket set... so I googled it and here you are! There is literally NOTHING else for me to try after this? So I will let you know how it goes buddy. Thank you. The word of the weekend is; 'Welch Plug'. Cheers Nigel

[@nigelcarren]

Good evening Dave, well I promised I would update so here we are and just maybe it will help somebody. In short; ITS ALIVE, and she revs higher than I can ever remember. As it turns out there are 3 faults. The Aluminium Welch plug I removed just as you did, but it was clear, so I carb-cleaned with wire and all the jazz whilst I was there. But in my little carb I have a little brass Welch plug, apparently this conceals a gauze filter which in turn feeds the high-rev jet (this is what didn't work with mine... I tuned throttle and she choked and stopped). I drilled a 1mm hole in this brass welch plug, then drove a screw in and pulled with pliers and there she was... FILTHY partially blocked gauze. This was in my carb-kit along with the little circlip. So I cleaned again and heard in a new brass Welch plug (so thats both Welch plugs removed and cleaned). Now she ran but it was all over the place.

[@nigelcarren]

Continued; So I fixed some new fuel-line direct to the carb and straight into the tank through the filler-cap (to eliminate the fuel line) and BOOM she ran superb. So I put it all back together by routing the new fuel-line properly through the tank-grommet and she ran... but kept stopping. I cracked open the fuel-filler and she went again... AHA BLOCKED BREATHER? So removed blocked foam from breather and jeez... Like a new tool. So thank you for your help, and the Welch Plug lesson. Keep up the great work. I can now start hacking through my jungle.

[@ZombieDaveAZ]

[@raymondjiii]

I'd love to see how those little rectangular welch plugs get removed and replaced (found on some 2 cycle carburetors.

[@obfuscated3090]

It's called an "automatic" or "spring loaded" center punch and belongs in everyone's drilling kit. They are very, very handy and one thing they avoid is hitting a solid punch too hard. They offer better control too which is why machinists use them. I really like your method because punching at an angle with traditional methods is inferior in terms of control and risk punching too far damaging the carb body.

[@steadyeddie7453]

You can also adjust the pressure the punch exerts by unscrewing the cap. Hard steel- leave the cap screwed all the way down. Soft non-ferrous metals- back the cap off a bit to avoid making a crater. And the really good ones like Starrett have replaceable tips. Cheers.

Wait...that's it? That's all it takes? Ha. Here I was a little shy taking those off. Will try it later today, my trimmer is bogging down when accelerating.

[@ZombieDaveAZ]

Lol Toad, let me let you in on a little secret. Trimmers are famous for getting clogged at the exhaust port or spark arrestor. It's hard to run a weedwacker full speed all the time and that's where the majority of the carbon build up comes from. Check that first. You still may need a complete carb clean but a carb clean by itself won't stop the bogging on acceleration by itself. You will still need to clean the exhaust. Good luck buddy.

[@mustangmatt7605]

@@ZombieDaveAZ your right I usually run my trimmers @ 75%throttle. Thanks

[@georgeiceman867]

What are the symptoms when those tiny holes are clogget ? It's gonna bog down when throttle up the chainsaw ? Thx.

[@ZombieDaveAZ]

Opposite of what you're thinking brother. Most welch plugs are a result of the manufacturing process. IE: after the carb body is made they have to put in the holes for the fuel to flow. Hi speed jet and the adjustment screw is tapped. Then the low speed jet is drilled and tapped. Under the Welch plug in a 2 stroke or pulse carburetor is a idle air passage that is preset . That works in concert with the low speed adjustable jet. When the machine runs on its own with just the low speed jet adjusted it is now time to apply throttle. Now all 3 passages work together to deliver the proper fuel air mix. Again now the hi speed jet is adjustable and they all must work together to deliver power under load. If you have done all the adjustment you can with the low speed jet and it still won't run, try cleaning under the Welch plug. Some guys get away with using a ultrasonic cleaner to clean what under the plug. I hope this helps you .

[@JOHNNYTUGS1]

Hey Dave, Great video & Thank you! I have a similar carb from what I can see, WT419. I got a rebuilding kit from Ereplacements there was no welch plug in it and i had to get the needle separately and it was half the height. I cleaned up the old needle and put it back in, do you happen to have a video of the way the diaphragms & gaskets go on and the gas lines too. not sure if it was me or the original owner that screwed things up. I pump the bulb and get no flow of gas, the lines are new. I think it's wonderful how you have answered replies for this long. You Rock!!!!

[@ZombieDaveAZ]

kzbin.info/www/bejne/oZCrmaGEn6uXrrM. This video will show how the fuel lines go and work

[@ZombieDaveAZ]

Diaphragms always go against a flat surface in the carburetor. The metering diaphragm ( the one with the metal tab in the center) goes on after the gasket.👍

[@rancha83]

Hey, with removing the plug you can clean those holes underneath. But what about that jet near the plug, can it be somehow removed and cleaned as well?

[@ZombieDaveAZ]

When the welsh plug is out, remove the low speed and hi speed jets. They are not always the same so do it one at a time or mark them. Also there may be a Small o ring that stayed inside the carb. I use a small piece of fuel line on the end of the carb spray straw and clean the passage that way. I hope that helps you.😎

[@steadyeddie7453]

The jet (brass insert) near the welch plug is the one and only main jet and it has a delicate check valve in it. It is made of mylar and if sprayed with a harsh chemical it will distort the mylar and it will no longer function. At one time they were replaceable, but I haven't seen them available for many years now. Also, Zama and Walbro do not recommend ultrasonic cleaning. They recommend soaking in fresh gas. Zama has a great website loaded with info. Maybe Walbro has the same.

[@paolocamilloni8819]

[@macknumber9]

I don't have the carb on hand right now so I'm not 100% but can you just get those holes from the throttle body cleaned out instead of taking the Welch plug out or is it too hard to get the angle right and reach in there

You would "probably" have better success using an ultrasonic cleaner if you want to avoid the welch plugs. But in my mind thats a $60 solution to a $6 problem. Know what I mean?

Your welcome. Once in a while it will surge up and down when holding the throttle trigger. Sometimes it will not idle even if I turn the idle speed screw to the right.

Hey JB thanks for the CLR tip. First I have heard of it. I will share with you that some of us guys on KZbin like to know how things work, how they fail etc. I can't help but think that a lot of guys have looked at that Welch plug and thought to themselves "I wonder what's under there. They sent me a replacement in my carburetor kit so I guess I should remove it. So the work is not unnecessary first of all. As far as it being a piece of junk, that is subjective and possibly open to debate. The owner obviously didn't think so. MY video is CLEARLY demonstrating another way of removing the welch plug. As far as I know, I am the only guy at the time of publishing this video (2 years ago) that utilizes the self centering punch method. I didn't say it's the only way or the best way. I said all the videos that I watched required locking down the carb and using a drill. So if you didn't gain a different perspective on this unnecessary chore, that's my fail or maybe it's on you. Thanks for commenting and I hope you subscribe. I have over 300 videos of just stuff.👍🍺

Anything is better than nothing on the filter. Maybe some foam that does not disolve in gas. And here is what's wrong/why gas is coming out. Hope it helps. kzbin.info/www/bejne/rX-3fIKrgNyLl6s stay safe and have a good weekend. 👍🍺😷
