Please tell us exactly what you are doing.
Mixture, exact content and % of each by weight. Include particle size for all ingredients. Describe processes used in mixing and consolidating.
Dimensions of finished device. Any thing known of humidity, storage conditions the and possibility of related water content of failed device.
Don't abbreviate.

2. List any points of agreement (especially if they are not matters of general or widespread agreement).
3. Mention anything you have learned from your target.
4. Only then are you permitted to say so much as a word of rebuttal or criticism.

First: it seems you are using too much fuel and too little oxidizer. 70:30 works with perchlorate, chlorate calls for closer to 75:20 as there is less
Oxygen available per moll. See below-
HOW did you distribute the petroleum jelly evenly through the mixture- Did you use a solvent, such as lacquer thinner? If so, are you certain it has
all evaporated?
While drying off the solvent, how humid was the air... Damp whistle mix doesn't work, regardless of being wet with hydrocarbons or water.
 THIS: chlorate mixtures should NEVER be dried in direct sunlight. Small amounts
of acidic impurities and moisture will cause a bit of Chlorine dioxide to be formed. Ultra violet light in sunshine then causes the Chlorine dioxide
to set your composition on fire! So don't- If it's the only oxidizer you have, learn chlorate's particular dangers, and how to minimize them.
 And tell your Chinese suppliers you want PERchlorate. It doesn't cost much more,
and you won't be his customer anymore if his chlorate kills you.
---------
Are you in India?
Yes, you can make whistle with Potassium chlorate. But it's a lot more dangerous-
If you stick a blasting cap in it, goes high order. Goes off from much less shock, than perchlorate whistle, probably a lot less friction as well-
I'll have to look the figures up. Minor contamination with Sulfur, sulfides, Antimony or Arsenic compounds among other things will all further
sensitize this, like pretty much any other chlorate mix.

Read the processing directions.
You need to mix well the iron oxide catalyst and powdered fuel, then dissolve the petroleum jelly in a solvent such as toluene or lacquer thinner, mix
the thinned jelly into fuel and knead it inside a large zip lock bag until a very consistent, thin mud consistency is produced with no lumps, dry or
differently colored areas.
Then the well powdered oxidizer is added to the bag, sealed with most of the air squeezed out and kneaded again until it is perfectly uniform color
and consistency.
The mixed fuel is spread out thinly in small bits on a plastic sheet or similar non stick surface and dried in the shade, outdoors, in dry weather for
SEVERAL DAYS.
Like this video, but do it in a bag, much less messy and smelly
Then tell us how it works/doesn't work.

MEK is hygroscopic. If you use it in humid conditions, it would attract water out of the air. Choose a non hygroscopic solvent.
Do you work at a fireworks factory?

Pressure and tube size does matter for whistle ? when I test my other whis.mix batch than little whistle. then I do other test
they fail.
