Ob1n ,
Homebrew fuel isnt difficult, but there are some pitfalls No1 being all ether isnt the same. What I mean is there are different grades and some arent suitable for our diesel fuel, in particular anesthetic ether can commonly have ethanol in it in varying proportions and ethanol supresses diesel combustion as its low cetain and high octain , the exact opposite of what we want. I have had a bottle of anesthetic ether with high ethanol content and my engines refused to start, the fuel made great weed killer tho.
Technical or lab grade ether is pure ether and is the best to use, as is the JD starting fluid(must be made useing lab ether), solvent ether can also have other solvents mixed in that may be undesireable too.
The next pitfall is in useing alternative oils to castor, in particular synthetics and mineral motor oils as these may contain combustion inhibitors in order to extend the crankcase life in 4st engines, so if going this rout be prepaired for some trial and error to find what brands/types work.
Kerosene,Jet A,lamp oil, light automotive pump diesel will work, with the first 3 being the better all round choice, auto diesel tends to be a little more difficult to get started and gives a darker exhaust.
Then its just a matter of mixing the ingrediants in the ratio to get your desired running/handling characteristics.
