I just got this and replaced every seal inside and out. Runs well when running... But I don't know if I'm preheating it right. I fill the spirit cup with denatured alcohol... Even did a double preheat and when the flame are still warming if I open it up it will flare and send a few yellow flames out the vent... Then run. Hate always getting soot off... Doing something wrong? Waiting for a part for the blowtorch preheat device but read you can start these by preheating
The preheat torch works and seals but definitely squirts more than burns...makes it worse trying to preheat
The pissing is what I found out is caused by an not fully cleaned and or opened little hole in the blow torch, or not enough pressure in the tank, or both,
Your preheating method using meths/alcohol is correct, but let it heat for a bit longer, it's best to preheat lanterns indoors. That is a grand old lantern.
