First time that I've needed to use an anchovy and it's backed out of the hole by about 1/4". Seems to have sorted itself now, but I've yet to ride it
Rubber solution on the filey-thing, rubber solution on the anchovy, poke it in and 1/4-twist, withdraw the pokey-thing and cut the ends flush
Added more sealant, most of the original stuff was up the seat tube, and pumped the tyre back up. I watched the anchovy slowly reverse 1/4" over the next hour before leaving it overnight. No new sealant visible at any point
So...is this reversing normal?
For a minute there I thought you had made one ****ing weird pizza.
If its backing out by itself, its probably not a tight enough fit. That said, it could also be that you've 'lubricated' it with the rubber solution which has now cured.
I've seen this quite alot with riders I know.
They don't really give much consideration on the size of the hole vs the size of the plug.
If it goes in easily, its going to come out easily.
Mostly, I find those little skinny anchovies are pretty inadequate for punctures that sealant can't deal with. You want the fatter ones.
Some people are just cack handed and can't seem to fathom how it works.
Some people lack experience in their use and haven't considered how it should work until they need to use them, do it badly and then decide that tubeless is shit.
I don't use rubber solution with my repairs, it seems superfluous.
I wouldn’t worry about it too much. Once the sealant has had chance to coagulate it should be fine.
I’ve not used an anchovy exactly but
here is a pic of a trail bodge I needed to do.
A knotted rubber band poked through with an Allen key.

the pic was taken back in mid May. The band is still there today. Bike in constant use.
Genius!

I haven't got that sort of dough. I thought I'd avoided all chance of puns too, doh!

This, I suspect, is it. Thanks
The elastic band is officially genius 😎

As in vulcanising rubber solution?
That's not actually necessary for a tubeless anchovy.
If it's a bigger hole you can double them over to try and add bulk and sometimes that works.
If the hole is sealed though, I'd just lop the excess off with a sharp knife and ride it.
FWIW I've had the same problem a few times. Followed by the anchovy tearing itself out completely on a steep climb. I guess the hole was just too big.
On topic with pizzas and tubeless - if you're fixing it at home I'd use a mushroom patch on the inside rather than trying a bigger anchovy. I had an anchovy that did similar and it took a few weeks before it was finally and forcefully ejected (tyre talk, not pizza aftermath).
Another here who doesn't bother with vulcanising solution. Not necessary and tends to make the anchovy too slippery, so it slides back out.

The instructions in my Weldtite kit say to use it. Seems like a good idea to me, belt and braces.
The only times I've used rubber solution it has made a mess and not contributed much to the solution. I go with the fattest anchovy I can get in the hole and then let the sealant do its job. It should be difficult to get it in or it's too small. Just done one today. First anchovy was a lot too small and a waste of time. Second (3x the diameter) was much more effective.
I have torn one anchovy out before but it was a big old hole and really needed a mushroom. Patched that inside with a normal rubberised (not feather edge) and then chucked it in the spares pile as it was a bit baggy headed anyway.
I just poke an anchovy in with smallest hex key on multi tool so both ends stick out. No prep. Never failed, always used the skinny brown ones and the thicker black ones generally go unused. Never thought to use glue on them, they're tacky enough and sealant does the rest. Snip them a little shorter when home but not flush with tyre.
Hit a bit of sharp rebar sticking out the ground the other day in Tignes (old set of steps that had rotted away). Big hole. I carry two sets of worms/anchovies, thin and thick.
Stuck the thicker one in there and all seemed good. Tyre was holding pressure and there was enough pressure to nurse it down. Got back up the hill and thought I'd chuck a bit more air in before the next descent. Whilst on the chairlift I could hear and then see air escaping and the worm slowly sliding out.
Probably need a mushroom plug, but the tyre is pretty skaggy after six weeks of various bike parks.... But I'm tight.
I’ve ridden best part of a week in Basque Country with an anchovy and cable tie to hold it in. Bombproof.
First ride out after 36 hours waiting for the rubber solution to cure and I'd got 55ml of Stans up the bike and me from the same hole. Larger anchovy definitely needed because it went in too easily
Tyre off and the anchovy's barely visible inside so I'll try a patch next and keep the anchovies for emergencies
Thanks all
