Avgas doesn't have many of the aromatics that the sniffers get high on, but it does have an octane rating of 110/130 and double lead content .

The EU spec fiddling here with petrol has seen the situation worsen with another tweak to RVP and volatility hike in the quest for low pollution and it plays havoc with old carburettors causing both icing and percolation.
Comme ça; this little siphon I use for getting the odd cup of petrol from a jerrican, the tap leaks at about 1.5 drips/min, this was taken on a damp 8ºC day and occurred within 1 min.
