Personally I would have some wood or leather inbetween the jaws of the pliers, when used on vulnerable materials like brass.

I think the pliers are plasic coated looking at the description on Amazon.

I pulled the ones out of my PD50’s by heating carb body with a hot air gun. Wrapped a pice of rubber tube around the jet and it pulled out pretty easy.

I thought this was a good start point, and obviously avoids potential damage.

Failing that though, a good mechanical grip, if they are very resistant, will be of value to get them moving.

Those knipex twingrip are a good tool to have anyway if you've something that's already been compromised.  My son bought my pair recently for a birthday present as I'd been looking at them in a tool shop.  Positively surprised at just how good they grip in comparison to some of my old and quite well used tools. Quite a neat size to carry in an emergency tool pack as contingency as they can be set to open quite wide in accommodation of different components.

I spent some time years ago as an optical tech for Boots and whilst there I used all rhe myriad of tools they have for adjusting, making and repairing spec fr3ames. All or most of the 'plier type' tools all had replacable nylon jaws and suited all sorts of jobs the we now undertake for carb twiddling and faffing about with these old bikes. Reading this just jogged my memory so it might be worth looking in brochures for optical supplies and technical support0 for 'that special tool' that you can never find....maybe. If I remember rightly, to replace sets wasnt dear and I found that a bit surprising in the optics trade.


Maybe worth a google search....?.
