Of the 3 H model's I have, 2 of them have enricheners that will not remain up. I suppose I have to purchase the assembly and replace it? Is this correct?

Yes, its called the Starter Valve. Jets R Us carries them, p/n 1166-818-2100 (SKU 018-500) $27.39. Just unscrews from the carb. I have never tried to take one apart, just replaced mine about 3 years ago (though honestly, I have rarely ever needed choke to start my 220)

There's a quick fix, probably temporary. YouTube "pwk choke repair". The guy struggles with it but you can get the gist of what he's trying to do in a minute or two of the video.

Just put a small cable tie around it, will give the rubber boot more friction on the stem and hold it up. This'll work so well it will likely be a long time until you repair properly lol
