I have an Optimus 111 and have been thinking about converting it to white gas which I would think is a cleaner burn and simpler to fire up. Is this a simple change of jet or more complicated? It is an old roarer design. Probably 40 years old and very little use but I am thinking of using on kayaking trips instead of gas. I hate having half empty canisters. Is it worth doing or are there other issues I have not considered. More flammable? Less safe?
