RT Classic's gone crazy?

[Greg2230]

Ok, so I got a Classic RT on Ebay and I aired it up, pushed the trigger, and it jumps into this ULTRA sensitive trigger (almost automatic). Ive fired an RT before and its not like this. All you have to do is touch on it and it jumps into like a 3 to 4 shot burst?? I checked the on/off pin and the sear and either seem modified? I dont know what to do?? Help please.

Make sure there is a space between the trigger and trigger rod when it is aired up. You probably have a very short pin in there. If you are using an adjuatable air source, lower the presure into the gun..
