Carb question

The power went out I could not finish my post...

I would go with the boots,because I`m confident that the sliders works great.The boots are not cracked and I don`t see any cracks but they are not new for sure.I should clean them where connects the heads,there was some kind of sealant residue on them and that might cause an air leak I guess.The spring and the whole mechanism is works good I checked.

Update:After further inspection,the boots are not so good as I thought.I find cracks on the inner side on all of them.After I scraped off the old sealant it became visible that somebody already try to seal them off.How could I miss that?New set are coming anyway.
