    Hi Jon An isocyanate is a 2 pack .Aerosols have a pull pin to release the hardener and have s short life after activation .As. John posted the solvents are best not inhaled and will likely pickle enamel paints . Tho polycynate is too vague to identify

    It’s a common problem .An exothermic reaction heats up the reaction mixture .A rule of thumb says that rate of chemical reaction doubles with a rise of temp of 10 degrees C and so it goes on .Mix small quantities at a time and use a wide pot .

    The O ring on the bottom of the carb is a source of erratic running if it’s in poor condition (crankcase compression loss)

    Have a look at the jetworks website ,they have downloadable plans for edf jets .The plans are for smaller edf units but they can be printed at different sizes to suit your fan . There are files for 3D printed parts as well

    That’s what I made it , there isn’t a law of conservation of volume so it’s not an exact science .Adding 100 ccs of oil to 5000 ccs of petrol doesn’t have to give 5100 ccs of 2 stroke
