Is there something I am missing? These two welch plugs won't come out? Any tricks to getting them out of there? This is on a HS series Tillotson on my 266XP.

Randy,
you could have had him


all you have to do is shake the carb real hard.


I have problems getting them to seal up when new.

In the off chance some trash made its way to the idle bleed ports.

I have not found a reason to R&R the plugs but the next one may prove to be the exception.[emoji57]

They plugs came with the kit, along with a small screen for under one of them, so I pulled them and replaced them (had to replace them after popping the hole in each). Tried shaking the carb hard, but they wouldn't budge. Anyway, the thing is back together and should be good. I am glad I went through it, because the carb only had the reeds and diaphragm in the top and bottom. No gaskets. So, I double checked the carb exploded view and sure enough, there was supposed to be gaskets on the top and bottom of the carb as well. I thought it was odd that there wasn't gaskets. I put the carb back on the cylinder, but I won't have a chance to test it until the "new" tank gets here.

My *pretty boy also found that the muffler screen was almost completely plugged as well. So, that probably explains why the saw had almost no power regardless of my attempts to tune it. Anyway, I ordered one of the cheap Hutzl mufflers for it. Didn't need to, but the OEM was pretty dented and rusted, so I said screw it. Once I get all this stuff on it, hopefully it'll be a runner. It's a saw I'm considering sending to the "Mastermind" next time he has his books open...

I have read to replace these if you see they are leaking. How can one tell if this is the case?

Hey, I know what I was going to ask ya'll! Were the replacement plugs supposed to be put in with the dome going IN to the hole, or facing OUT of the hole? The exploded view was worthless on this. When I tore it down, one was up and one was down. I put them in with the domes facing OUT.

The dome facing out, then you knock the dome in to seal them.

Thanks Genius! I'm going to open the bottom back up, then. I put them in facing out, but I didn't seat them. Just use a brass punch and give them a tap?

Steve the installation is what I struggle with.


Did you shake up and down or side to side?

Yes, that should work.

Some guys recommend putting some sort of sealer (nail polish) on the edge before you seat the plug. I have never done this, all the plugs i have installed have seated with no sealant.
