    I've refurbished my Optimus No.1 and cant get it to light. I'm using metanol and I light the preburner bowl which I fill from the fuel coming up from the jet, get it hot but still cant get a flame. All I get is gas/air from jet which doesn't ignite, after the burner pipes cool down I hear a gurgle and then ethanol starts to squirt out of the jet. Is the ethanol not suitable for this sort of stove ( becoming too rarified?) and should I just use paraffin which I just found out today is available in local shop?

    You should be using Paraffin (kerosene) if it's an Optimus No. 1.

    Preheat with methanol.

    Cheers

    Tony has beaten me to it. Paraffin as the fuel and preheat alcohol. Normally we use ethanol i.e. methylated spirits (not Jamesons) but methanol will also work. Down side with methanol is the flame is damned nearly invisible so you can't tell when the flame is dying down.

    Ok. Thanks for that guys, it all makes sense now and hopefully I'll be getting this thing lit soon.

    Got the paraffin, works a treat. Nice blue flame when heated up and under pressure.

    I know its not normaly done but would a restrictor like the one used in the multifuel 111 work. Otherwise a bigger jet but still remember for this type of stove that kero is the safest and most powerful option
