Question CA M14 Trigger delay

So I got's me a almost new CA M14 Scout (a very nice gun it seems). But it has a slight trigger issue. If you pull it reasonably fast, it works great (semi or auto), not a problem. But if you pull slower, there's a delay. The slower you pull, the more the delay, up to a point where the delay is 2-4 seconds, or just not fires at all. Literally you hold down the trigger.... ..... ..... .... boom. :S

This thing has an incredible rate of fire with a Sanyo 2400Mah 8.4v. Never fired an AEG this fast.

Any tips greatly appreciated. Seems like some really minor issue that I assume would be a quick fix.

Thanks,
Cheers,
Alex

Sorry for giggling, but you are saying that when yo upull the trigger slow there is a delay, and when you pull it fast there isn't a delay? See why I'm laughing, the way you described it is like "Why does it take longer to walk to the store and less time to run there?"

When I mean delay, I mean delay from the time the trigger reaches the end of its travel, and the start of the piston moving. I'm not as stupid as I make myself out to be

Wasn't pointing you out as stupid, just pointing out the humour about your description is all. You know I dont make people out to be retards, I just see the funny side of things.

So, you think it's a mechanical delay or electrical?

Hehe, I'ma kiddin' mate. It's all good.

I don't really know. How would I be able to tell? It's seems to be pretty much dead silent first.

Got me there. Have the gears been swapped out at all or anything?

I just got it, supposedly 100% stock, only 300 rounds fired.

Hmm, so youlike to squeeze the trigger like it's a woman's nipple to get that sniper feel out of it, and don't like the jerk feel from shooting it, am I correct?

Wait a minute, I just realized that gun has shitty little wires through out it, like #22AWG or so, best case #20AWG wire. Could be the wire resistance is too high to get a fast response out of it. Chef/Jackals brought his over for me to inspect before he sold it, and I noticed the shitty little wires in it (was stock). Generally AEGs have #18AWG wire running through them, is why I noticed the tiny little wires used.

Shit, you got me thinking more. Does the distance change when you do both methods of trigger pull? It's the amount of travel the contact block does via the trigger that determines the "delay". It can only move so far and does so no matter how fast it's pulled, it only goes that distance to make contact with the 'contacts'. Starting to sound like a design/normal thing as opposed to a "problem".

You could try a new switch assembly

Alex and I were talking about shitty wiring. Perhaps that's the case? As Stalker mentioned, it has sub-par wiring.. so.. who the fuck knows.

I don't trust M14s cloned from GG M14s...

Your switch assembly might be pooched as ThunderCactus said, It seems that your trigger assembly is completely covered in carbon from arc's.. So when you pull the trigger fast, it scrapes some of the carbon off exposing copper which makes a full connection and causes it to fire, while when you pull slow.. it barely/doesnt remove the oxidation layer so it only fires when it completes a circuit, which is whenever the trigger assembly finally dislodges from the contacts and makes a complete circuit... thats my 2 cents of whats wrong haha

What? The CA looks/feels like a great AEG. The wiring (at least the one in the stock) is quite thick, not the crap used in chinese clones. Thus the really great fire rate I bet.

Looks like it's time to open it up for an inspection. How do I strip this thing? The trigger guard DOESN'T go down like a TM. Even if I pull to the rear first, then try to swivel it.

CDN_Stalker:
How can it possibly be the wire resistance if I pull the trigger fast, and it fires immediately, and on full auto the fire rate is faster then anything I've ever fired?

The amount of travel doesn't change. The feel of the pull doesn't change, nothing mechanically in the trigger seems to change at all, just if I pull slow, I have to wait. If it were like you discribe it (not moving far enough to make contact), then it would never fire when I pull slow, instead of sitting there with the trigger pulled for a couple seconds, and then suddenly firing.
I should make a video perhaps for your to see exactly what I'm talking about?

Thundercactus,
I hope I don't need one, but how much do you think one will run me?

Nova316,
That could be it.

Kos,
Bah!

Thanks guys,
Cheers,
Alex

Dunno, shot in the dark, just something I remembered about the CA M14 that stood out and bothered me was the wiring. Of course if it's just started doing this, it could be the carbon build up, but there has only been a few hundred rounds fired through it so that wouldn't be the case.

Oh, one thing I don't know if CA copied the flaw from G&G or no, but one of the contacts in the trigger assembly literally gets cut by arching. Will take a couple thousand rounds (if semi only), but happens with the G&G. The copper used is thin, and each time the contact block gets near the contacts, an arc happens and eats away at the metal right where the bend is.

Alright, I'll have to take a look as soon as someone tells me how to take it down :P
