The only difference between the diesel and gas genset is the carburetor,
which is just different, not more expensive.

Gasoline and natural gas engines run with a compression ratio of between 8.5:1 and 11:1 nowadays. Diesel engines require a minimum compression ratio of 22:1, since diesel fuel requires a lot of heat and extreme pressure to ignite. Natural gas engines use carburetors, while the newer gasoline engines are using fuel injection.

The diesel genset engines use direct injection, there are no carburetors for diesel engines. Diesel fuel cannot be atomized by a carburetor the same way gasoline can, since it is a fuel oil.
