Hi All- Just got a Primus Omnifuel and am taking it for its maiden run. Ignore my post title- I cant edit it but its an Omnifuel! First tried an MSR butane type canister and all was good. Switched the jet to the correct one for white gas, filled the tank with Crown white gas and the trouble started. I can prime it but cant get it to go to a blue flame. Ive cleaned the jet repeatedly, used compressed air in the line and intake on the pump, checked the leather plunger on the pump, checked the small brass and oring bit that seals the pump, removed the fuel filter finally on the intake and it doesnt make a difference. The output pressure seems sporadic no matter what I do (even though there is pressure in the tank). By some miracle I got it working a single time and then back to the same problem. If I do get past the priming to the blue flame- it only lasts a few seconds before it sputters and goes back to a big fireball of yellow flame. What is left to check? About ready to give up and see if I can get a replacement.
