Well, it's not about a four stroke, maybe it's in the wrong section, but I hope it's going to be of inspiration to someone.
One of the choke holders, broke off and I did not want to order and wait for it, so I took matters on me hands;
a little pour of a 2k stuff, made for repro parts with help of a silicon moulds, (I did use cardboard in this case);

and the outcome;

brought to spec to accept the proper thread (M12x1,25) with makeshift lathe

easy to tap indeed...

a chamfering of the bottom and an o-ring it's all it takes!!
