Rusted Automatic Draft Control on 2N

I'm now soaking the whole works in diesel fuel for a couple of days.

I've thought of cutting the spring away to gain access to the pin where the plunger joins the fork. Then maybe I could cut the yolk off and save the plunger?

Your (hopefully better) ideas?

Thanks,

Paul

Here is an old post of mine on the subject.

You will need to heat the yoke red hot all the way around the threaded part and then you probably can turn it with a bar about 2 feet long. If it doesn't want to turn when it is red hot you should not use too much force as it is possible to twist it off behind the yoke.
If it won't budge hot then let it air cool to room temperature and try it again with the bar and some WD40 or something like that.
Do not cool it with water. Let it air cool.

I have heated it, but not yet red hot (I have no oxygen...only mapp gas) and cooled it by plunging into diesel fuel. Am I likely to have caused harm in so doing? That is: why your admonision to avoid cooling it with water?

Thanks,

Paul
