I can get better pics after I get off work.
Premixing is a good concept, anything to get rid of the 4 stroke oil in the chambers. A company called Real World Solutions does rotaries in small planes. They had an adapter that sat between the oil metering pump and the block. It had a fitting on the top and blocked off the outlet from the block to the metering pump. You hooked up a small tank with 2 stroke in it to the fitting and it used it as it needed it. It accounts for high boost levels by giving it more oil, which can't be done with premixing unless you know how you are going to use every gallon of gas.
Another thing to consider is using Lead Supreme 130 additive. It WILL serious mess up converter and slowly burn up oxygen sensors. The nice thing is the O2 sensors can be bought for 10 bucks because they are the old single wire kind. It's definitely not a street legal thing to do, but a little leaded gas never hurt anyone (tetra-ethyl lead in leaded gas breaks down in sunlight). I'd stay away from the toluene mixing that I used to do with my 1G, it acts as a solvent to oil and pulls it right off the seals where you need it.
