it starts deflating again. I can't think what's wrong with it. When I bought it, it came with two nuts at the end of the valve (before I put it on the wheel) I think one is to go on the outide of the rim and one on the inside so the valve doesn't slip into the rim.

Actually the 2 nuts go on the outside of the wheel, they lock together so the stem cannot pull back through. Be sure when you tighten them down you leave about 4 threads from the bottom, when you go through a turn the wheel flexes and can pull a hole in the stem base, causing you to get a new tube. Be careful. Now, if you take the pump off the stem and then it leaks, I'm willing to bet the valve stem core is loose.

You really should stay with the kind of valve that you already have. Schrader valves won't fit through the holes in the rim sized for Presta. Presta valves don't work well in the rim holes sized for Schrader without an adapter. Tubes are sized with a bunch of numbers like: 700X28-38 or 26X1.95-2.25 The first number reflects the diameter of the wheel and must match your tire size (look on the sidewall) exactly. Tubes fit a range of widths that are the second and third numbers. As long as your tire width (look on the sidewall again) fits into that range you can use that tube. The people at your local bike shop will help you if you need it. Tubes there are reasonably priced. HTH

It is so easy to pinch the tube on small tires. Try again! Monkey Grip Patch kit or another new tube, look for the double hole from screwdriver pinch. rounded tire irons and lots of talcum powder. I partially inflate the tube so it does not get twisted tuck it in with one side of the tire already on the rim. And then suck the air out this makes the tube smaller and talcum lets the tube slide around now carefully turn the other side of the tire over the rim.

Check the valve inside the valve stem.
There is a special wrench for it, about $1-2 (cheap!).
Check to make sure it's tight. If not, replace the valve (core) with another one.

If its a car style valve , a schraeder then the centre of the valve needs tightened with a valve key , if its an ordinary cycle valve maybe you have nicked the tube but it sounds like my first suggestion.

If it inflates and holds air until you remove the pump then the only reason can be the valve core---put some spit on the core and see if it bubbles indicating an air leak

tighten up the valve core and if that doesnt do it, its probably a faulty valve, and the two nuts are to stop the valve slipping as you thought

Just dab a little spit on the valve stem,if you get a bubble it's the valve leaking,if you don't ,you have pinched the tube.

The valve itself could be loose ?, try using a valve tightener on it !..
