Rapid help please

[miller]

Hi Folks I bought a rapid mfr a few months ago and all been until today, It's started making a strange popping noise on firing. I will be grateful for any thoughts on what might be occurring.
Thanks Pete.

Is it low on air?!

[miller]

Hi mate plenty of air, sounds like noise is coming from around block area not barrel end.

Probe not dealing properly..??

Here's a service guide that details some common faults.
It sounds like yours is the third one on the list.

Thanks mate will give it a look.

It will be the pellet probe or the small o ring on the valve stem.
There is an M4 adjuster screw at the back of the bolt with a small locking screw access via bolt gate, for the probe


The get at the valve stem o ring, remove bottle, unscrew Reg, unscrew valve cap, remove return spring and pull out the valve stem with a pair of long nose pliers or a magnet on a stick.

Cheers Bb, it started making noise today when it dropped cold, after being back in house for a few hours and warmed up seems to be OK again. Will try it again tomorrow. Adjusted probe a bit anyway.

if it's not barrel and probe area but sounds like it's coming from block it could well be a badly fitting stem in the valve body.alowing air to vent back up the valve body and into block.could just be a tired stem oring agrevated by the cold.
