Burning taste after a new build

Ok guys I know I may be starting to get annoying but I'm desperate

I just put a new build on my moonshot and anything above 50 watts has a horrible burnt taste.

The build is a dual Clapton with a single strand of 26g kanthal spacer coming in at about .15 ohm. I know it is not the wicks they are good, and I run the exact same build on my freak show and my mad hatter with no problems.

Any thoughts???

Wicking is my first thought for most/any RTA problem.

That's what I thought to so I changed the wicks but still doing it would wicking give burnt metallic taste???

Not enough wick through the coil could cause that.

Could that coil need a break in time on the rta similar to a prebuilt coil say the crown for example

Naw, a Clapton build, or any build in a RTA should be good from the start.

What type of wicking material are you using? Can you post a pic of the deck wicked up?

That's what I thought I'm using organic Japanese cotton and yeah I can try to get a picture in a few minutes

If it's a wicking problem wouldn't it be leaking too

Did you heat the coil prior to wicking, might be latent machine oil on the coils giving a foul taste.

It does seem to be getting better over time now up to 60 and no metal taste

Doesn't look terribly under wicked to the point it'd cause burning to me, maybe a little on the upper left area in that pic, but looks fine for claptons to me.

Is it just me or does the left strand on the upper coil look burnt if so could that be my problem??

The coils look awfully close to the barrel. I can't tell if either is touching it. However, that could also be the cause.

Nothing is touching. What are you saying could be the problem?

Before wicking, you did check if the coils start glowing from the middle out, didn't you?

when you fire, with the RDA open as seen in your picture, are there any sparks between coil an barrel?

When firing to check it the spacer wire heats up then the Clapton but I did notice the legs were heating up really fast as well and no noted sparking I think I burnt the coil when pulsing them I was running 100 watts on previous build

Try squeezing the coils, that might help, getting rid of the hot legs.

Either your leg is heating to fast and it's burning the cotton that would give you a burnt cotton taste. Also the metallic taste is probably oil. Next time you make claptons when you first fire them see if it makes any smoke if it does it's probably machine oiled burning off so heat them until you don't see anymore smoke and you should be good. I got the taste too the first time I did claptons but after doing what I just said I never had a problem since and I primarily use claptons or fused claptons now for months. Also make sure there's no little strands of cotton sticking up that can cause burning too. Hope this helps!

Top coil looks like only first wrap is heating as its the only one discoloured, bottom coil looks like you would expect. Maybe top coil is so close to the side its just touching when it heats up (it will expand a little bit when it is hot) that would give you a metallic burnt taste like you get when you hotleg in a genny.

I'd try loosening then retightening the grub screws.

I remember having the same kind of thing happen when I first started using RDA's and learned to always retighten everything after dry burns.

Usually if the screws aren't tight your ohm's will jump around

It could be oil as Scratch mentioned.

Did you wash the heck out of it before doing the first build?

If it is oil your best bet is to take out the wick and soak the deck in some vodka or rubbing alcohol then give it a good scrub before re-wicking it.

also looking at the picture that one leg is touching a lot of cotton in my experience when the cotton is touching the leg it tends to burn especially if you have a hot leg.

You guys are awesome thanks for all the advice

I'm almost positive it was the hot leg and I am going to yank that off probably in the morning. As a noob builder what causes the hot leg and what can I do to prevent it on my next build.

You'll want to pulse the coils lightly, and squeeze them (with power off if you don't use ceramic tweezers), pulse, squeeze, brush them until any hot legs/spots are gone and you see the coils glow evenly from the middle out.

Then you'll want to try putting the chimney on, and make sure its not touching your coils. Check resistance before and after chimney, should be the same.

Hot legs are pretty common with Clapton coils I've used, then you just work them out, and they are good.

I'll give that a shot take

On a positive note I threw this build on another atty to regain my lost confidence working like a champ

When you get good enough though fused Claptons are great

I would double check that the coil wasn't touching any part of the barrel after you assemble it. Had a coil touch the cap on a Vector and that made a pretty awful taste. A tip for avoiding hot legs on the Moonshot is to even up the leg lengths. This might be tough to describe, but Ill try. When I wrap my coil I make one more wrap than I need. I take the leg that would come from the top of the coil down to the post hole and unwrap until the two legs make 90 degrees angle. Then I take that top leg and put a 90 degree bend in it so both legs are essentially coming straight out of the bottom of the coil. Thsi makes it much easier to position. If this doesn't make any sense I can take a few pictures.

WTF? That is an ugly ass bend...lol...I talk too much shit for my own good sometimes...

Yes, that one is not pretty. I usually try to place it a bit higher, but it wasn't showing up well in the picture. On the Moonshot, it makes positioning the coil in the those weird ass post holes a bit easier.
 
Greetings everyone, I wanted to post an answer to this weird issue when building new coils, have sufficient cotton all seems to be good then you hit it and you get this ewwwh burnt taste! SO I think from my experience for a year of vaping that some cotton is touching the LEGS of your coil. Simply after priming the cotton with juice make sure no cotton (after expanding when saturated with juice) is touching the coil legs. . There you go .

If it's not the wicking then make sure you're legs are tightened down and that they're heating up evenly. As others have said make sure you're claptons aren't too close to the top cap and causing shorts. You can usually tell if it's a short or the wicking because if it's a short it will taste really burnt in like a second whereas with wicking it would be more flavorless/dry hit tasting with subsequent burning taste.

I don't get shorts really anymore but when I used to I could always tell because it'd go from normal tasting to super burnt tasting like instantly. Obviously heat or wicking can't account for tasting burnt THAT immediately.

Another thing that's helpful when wicking to avoid shorts is to push any cotton that's close to your legs away and towards the juice well.

As far as wicking goes the cotton should go through the coil easily and without moving the coil. Not so easily that there's no resistance at all or barely any but just enough resistance.

You shouldn't feel like you really have to pull hard to get it through though. You'll get an idea of it the more you do it though. Yeah I would think a short is more likely if it's tasting burnt at 50w and it's only a .15 build.

After reading your post again the single kanthal wire might be causying your coil to short out. I know this can be a problem with contact ribbon wire could and why you often times have to wrap each wrap over one another like a tinman build.

I'd get rid of the round wire or just make sure your coil is very tightly fused together. Might be hard to achieve this without dry burning to hotter than you want depending on how tightly wound the coil was wound in the first place.

Your cotton is too tight inside the coils.
Trash the cotton installed and roll a loose strand of cotton.

As many times as I install cotton in rdas I could probably do it blind folded. You'll have the feel for when it's too tight or too loose. Also Stay away from free cotton that comes with rda, rita. Buy some cotton bacon or prime or japanese organic (real jOC not chinese shit rebranded).
