According to the instruction manual and literature, my Coleman 424 is designed to use white gas or unleaded gas...no conversion required.  I bought this one in the fall of 1999....if yours is older and your instructions aren't clear, I would contact the manufacturer.

unleaded as well? I have a wonderful old Coleman whitegas that won't die,
but the exorbitant price of white gas lately has me wondering if it could be
converted over in an emergency? Do the dual fuel ones have a different jet
or ????
Thanks,
