The present invention relates to an internal combustion-operated setting tool for driving fastener elements such as nails, bolts, pins into a substrate, having a fuel source, with a fuel feed line from a fuel source to a combustion chamber and having at least one dosing device ( 30 ), which is arranged between the fuel source and the combustion chamber. For improving such setting tools, a displacement body ( 50 ) is arranged in a chamber in the dosing device ( 30 ) for forcing fuel out of the chamber, whose displacement volume can be adjusted.
