Walbro welch plug sealant

[Wayne Graham]

Hi, does anyone know what I cal use to seal the area around a welch plug in my walbro carb? I have tried clear nail polish, lasted 1 hr and pealed off cloging the main jet. So let me know what you have used with success.
Thanks for your response.

It's going to be hard to find something that tolerates gasoline. Permatex makes a sealer that is impervious to gasoline, but I don't know if I'd recommend it for this use.

Why do you need a sealant? Is the seat around the plug damaged? The plug should fit tightly enough to seal it just fine.

Put them in dry. Tap gently to distort into place.

I have never seen one leak...

Out of the countless saw carbs i have rebuilt I have never removed or replaced a welch plug. Guess I have been lucky.

If it is one that is still in the saw and has not been replaced... maybe a few light taps will help to stop it from leaking.

What is that plug for anyway?

How do you even get the plug out of the carb? On my Walbro WT model there's no hole behind it to poke it out. And if I did get it out, what do you find behind it? SOmething to clean out or adjust?

You use a tiny chisel and "spear" it.. I use the Zama tool... Often if you just tap it with a small punch it will free up.


It covers hidden bores or passage ways.

it covers up the three low speed jets and the feed from the metering side.

although I could be wrong
