Seeing kits available from Primus eg. Eta Spider/Express Spider, Gravity to make them multi fuel and seeing Koveas line up of Booster Dual Max, Booster +1 and Hydra whom are jetted for dual fuel (Naphtha and Iso-butane), has me wondering if, with the aid of a bottle and pump, the Kovea Spider with its ability to burn liquid butane (inverted canister), might be run on Naphtha? The thought came about due to needing a pump/bottle combo for my Primus Omnilite (long story, don't ask) and picking up a Kovea pump/bottle on a local online auction as a make do attempt on the cheap (around $25 US delivered). I'll need to source a Primus hose for the Omnilite once my bottle/pump arrives but that's a question for another day. Any thoughts on the matter or might someone have already tried this? (Kovea Spider on Naphtha) My first thought on issues would be ability to heat enough in a prime, the spider, and I'm interested in knowing others thoughts. I've kept the Omnilite mostly as a multi fuel option for my Trangia 27 despite not using it for quite some time, preferring the quiet of my Trangia butane burner and original alcohol burner as well as a parting of the ways with said bottle/pump. I spotted and won the Kovea bottle/pump yesterday and hopefully arriving in the next couple of days being shipped today. I'd read in here somewhere of a Kovea burner head being used on another stove as a silencer and it got the creative thinking going and enjoying reading this communities forum thought I'd see what others thought.
