Krytac mk2 shimming is hell

[Katana]

Still haven't gotten to the bottom of it. Hop up works and looks fine with no tears to the bucking. I even tried teflon coating the end of the bucking to help seal. Hop up has both spring that come with krytacs. Tappet plate spring is on the right way round even though I don't know if that would affect compression. Compression parts inside the gearbox have good compression. I can't see that fault as to why it just about makes it to the end of the garden at about 20 metres.

I may make a post over at the Krytac Owners Group forum to see what the company techs at Kriss have to say as they might know about this issue.

Don't have a clue.

No point going to the krytac group as your problem isn't model specific. You have obviously got something wrong when putting it back together but its hard to know what for definite without having the gun in front me.
Take it to your local tech and let them take a look.

That's the reason why I'm the one that is working on it. All the techs in my area either suck or I haven't heard of them. Last time I took a gun to my local shop, they shoved one shim on every gear in my mechbox when it was perfectly shimmed before hand and gave it back to me sounding crap which is when I said that I would never give it to another local tech again. That's just one bad experience I have had with teching in my area. Another guy said that he would do all kinds of things like correct AOE, tried to sell me this garbage about how he was going to make my hop up shoot 250 feet with this special mod which was complete garbage and then all he did was install the MOSFET I asked him to install and that took a month to do and he had nothing else in the queue. The first shop I talked about took 2 months to order and put in a small amount of wiring.

Sorry I'm going on a rant here and don't mean to and maybe I should start searching for a better tech in my area if there is one but I have lost faith in techs due to about 5 bad experiences with them.

I get where you are coming from there is only one tech I would trust to touch my stuff if I was too busy. I have fixed plenty of stuff that so called airsoft techs have bungled up. As I have stated in posts before most airsoft techs are just enthusiastic tinkerers and have no real engineering background.
What area are you in and can you post it if necessary?

I'm down in Essex. I'd rather avoid posting it if necessary and kinda want to leave that as a last resort. I do have someone with a similar issue who has a tech looking at his and he said that he'd get back to me as to what it was. I'll ask around and try different things and if I can't find any fixes for it, looks like I'll be posting it to someone with an idea of what they're doing

Okay so I think I have cracked it (more like a tech at krytac lol) but it was very easy (for me) to miss as I have opened this thing up a million times (more like 20) and just couldn't solve it.

The sector gear has scratches and wear on the top of it which I thought was a bit weird and the tappet plate is a bit stiff when the box is together and also feels like it snags on something. I believe that the sector gear shimming was too high so the tappet plate was grinding against it and the timing was off. Can't believe I didn't see this because it was literally right in front of me the entire time.

I mean just look at this....

BAM Right there. Very unusual problem because I just didn't think it could happen but it looks like it can.

Bearing in mind that there is a shim on top of the sector gear and when I shimmed it, it was NOT rubbing on the face of the gearbox. The bearing are raised in the gearbox anyway so it couldn't touch the face....I think it couldn't anyway, not the first time something has surprised me.
