Very first fill for my TNT F2 kit. Ran down the track and the O2s were .960ish. WTF? Tried leaning the fuel jet down one size and no change. Only picked up 6-tenths on a 150-shot.

So two days ago I crack the bottle and air comes out, not N2O, air. Go to the shop where I get fills and everything else, and luckily I'm in good standing with the manager. He says bring the bottle inside. He cracks it open and gets a lot of air, and then a touch of white at the end of the bottle. Shakes his head. Tells me he will give me a refill at no charge. Awesome. <img src="gr_grin.gif" border="0">

So I will give the bottle another try tonight at our club meeting at the track.

 

its possible you might not have a good seal somwhere. open the bottle and check ALL your connections from the bottle to the jets, it happened to me a few times.

 

I checked all that stuff. I have heard others say "it's just a matter of time until you get a 'bad fill'".

That sounds like a bad fill. When you open the bottle, tilt the nipple down as if were in the car. Alot of white should come out. It could also be the shop, how do they fill the bottle? What procedure, freeze and siphon, pump, warm and siphon?
