K5.9 carb on a .21bb engine

[SuperSandLesbian]

So I've recently bought a savage 21 that has a stuck carb, n I mean it doesn't budge, I've it in soaked in wd40, nitro fuel, heated it up and it won't budge, I have a k5.9 engine lying around and wondered if I can stick the carb from that onto the 21 engine?
Just finding cheaper alternatives as I want this to be a budget build.

remove the dust boot and all of the needles, spray some penetrating oil and and start tapping that slide using a piece of wood and a hammer, should be enough to get it moving again. Also those two engines have different sized carb necks so you cant use a carb of the k5.9 simply because it doesnt fir

I've managed to get it freed now, I wacked it a few times with a spoon 😁

It should work if it fits.
You may have to install a 6mm or 6.5mm restrictor for it to run right, but I'd try it.
I don't know how big the venturi on the 5.9 carb is, but it's probably too big for the .21 BB to be efficient.

Your current one:
Try soaking it overnight in denatured alcohol - some people use Naphtha.
I don't think that WD40 or fuel will dissolve the gunk that's binding it.
I'd be something else if it's rusted, but if you remove the needles, idle screw, and take off the boot (if you haven't already) and give it good soak or two, it should free up.
