Stuck Choke tube

[Alex1Nat2]

I have recently bought a Beretta 303 but the choke is stuck in.

I have tried standing the barrel in a pot of WD40 & soaking it for over 24hrs.

WD40 level was over the top of the choke inside so should have been soaking down & up.

 

Any ideas?

 

Suggestions have been hot oil or disc brake clean but both sound a little scary!!!

 

Any help would be appreciated.

Just an idea. Heat the barrels witha hair dryer on the outside and inside. then cool the choke only with oil froma spray can (i.e. wd40) hopefully it should screw out due to the barrels being slighty expanded

 

Have you got the choke key and that? It is possible someone has cross threaded it which will mean brute force will be the only thing to get the choke out and you may have to get a new one

Put barrel, well protected with some rubber, (a bike inner tube will do) into a workmate bench or a woodworking vice. Tighten it down just enough that the vice grips the rubber and barrel, so it doesnt turn.

 

Depending on your type of choke key, try to extend one on the lugs on it to give some leverage. I made a choke key for this one day and tack welded a short bar onto it.

 

Heat the outside of the barrel, I used a heat gun, but be careful they are a little fierce. While I prepared myself with a small hammer against the home made choke key, the missus sprayed the inside of the choke with plumbers freeze spray, I gave the choke key bar an instant sharp smack with the hammer and got the choke moving.

 

I worked the choke back and forth gently and removed it. Somehow it had got coked up on the threads, which nicely wedged it in place. Dont be fooled into once you get it moving, grunting the thing undone. Its a good way to strip the threads in the barrel.

 

Constantly loosen the choke by unscrewing half or quarter a turn and then tightening up a little. This stops the crud from bunching up again in the threads and jamming the choke or stripping the threads.

 

Cross threading is very unlikely, but if you really suspect it is, best way is to split the choke down its length, starting it off with a small dremmel. If you try to force it undone, swarf will come off the threads, bunch up under the choke, and if you havent already got a damaged barrel thread, you certainly will have by the time you force it undone. A new choke is far cheaper that getting the threads in the barrel retapped, as long as there is enough metal left to re-tap.

Thanks for the suggestions.

 

Will start with the hot air idea. I have a mate with a heat gun so will see how it goes!!!

 

I've got the original Beretta choke key so will try small taps with the hammer to start with.

as said by covlocks pllumbers freeze gas would be idea rather than wd40 to cool the choke

soak the choke / barrel in diesel.

 

use grease to put the choke back in.

 

also might want to use a thinner and some oil.

plumbers freezer spray here too!

 

we use it at work for releasing stuck nuts and bolts, never failed yet!
