faulty gamo magnum 3000

[ellir0305 9]

i have an old gamo magnum 3000 which has a little issue it intermittently releases in a slow ticking instead of firing, that is when you pull the trigger, the piston creeps forward and ticks as if the spring or piston is sticking. when it fires cleanly it is fine and has good power which suggested the piston seal was good.

 

so i fully stripped the gun and polished and deburred the internals and greased as appropriate and inspected the seal, the problem has reduced but is still apparent. the spring was warped somewhat and having looked at an exploded drawing it appear the piston weight is at th wrong end of the spring suggesting tampering by a previous owner. i am going to change out the spirng and correct the positioning or the piston weight hopefully curing the problem.

 

It also doesnt catch back on the trigger when cocking so i think the trigger needs a little more adjustment.

 

Has anyone else had these problems and if so how have you cured them?

No responses?

 

Respectfully. Bin it and get yourself a really top springer like a Weihrauch or Air Arms. You sound like a decent fellow who knows a thing or two and anything from this cheap rubbish is like as not, beneath you.

 

Regards.

cheers for the response. i have a hw 90 as my main gun and a ratty. i have done up an old meteor for plinking and i and just doing this one up for fun really i like a bit of tinkering and gun smithing i am going to re-do the stock as another practice before i do my beretta shotgun. i know gamos are a bit pants but its more of a challenge then, i think i might have to many air rifles too ...

 

has nobody come across these problems before?

You can NEVER have too many air rifles, just not enough amunition!
