Just a thought guys John Deere starter fluid is over 80% ether 7 oz is 210Ml x .8 approx 170cc ether per can the propellant is butane I believe, you can consider the liquid left as 100% ether
thus 170 x 7 cans really 1190cc thus more than a litre at $5 a can x 7 cans about $35 say round up to 40 would be less money martin . I think for out out of USA use this is what Davis
suggests for making diesel fuel martin
