Mg725 possible problem

[Boneill230]

New to the forums and wanted tO get some info. Just bought a snap on mg725.
Thing is 2 and a half years old I checked the serial number as soon as I brought it home. Been using it in the shop for about a week, thing works great, No complaints on power, ran into some tough stuff and no problems at all. But today I heard a leak coming out of the exaust, is this normal? Or is it a problem? Guy I brought it from said it was rebuilt 9 months ago so the internals I'm guessing are good might be an o ring or something. Bought it for 260 so I don't think it was a bad deal. Thanks in advance for the help

Is that leak when the trigger is pressed or not pressed?

I haven't looked at the parts breakdown, but I'm sure it's like just about everything else. There should be a plastic seat in the air inlet. It usually gets brittle & cracks allowing air to bypass.

I finally looked at a parts breakdown. Look at #31 & 32 closely for wear.
