2 stroke, 100:1, for me premixxing works ideal because it helps lubricate the camden as well.

omg please, please use 2 stroke. It is meant to burn AND lubricate!

100:1 is a good ratio. Usually people pick something around that with an easy amount like 1oz per gallon or something like that (only used that as an example, not sure on what ratio that gives you)

Never use 4-stroke (it produces excess ash), use 2-stroke oil or Marvel Mystery Oil.

For normal use I put 6-8 oz. of MMO or 2-cycle in the tank before topping up with petrol.

4 stroke motor oil "WILL NOT" mix with fuel! As mentioned, use 2 stroke only.

if your going to premix use what is made for our cars, get some idemitsu fuel lube, its great. I mix half oz per gallon, no smoke, with little odor from it.

Just my personal opinion, others have great results with other more readily available products, but if you plan to keep the car for a while i think its worth buying a case of idemitsu.

Bliffle dont you also have an operating OMP. I had thought you did (but could be wrong)

I use Millers KB2T ratio 250 to 1 - WITH the Oil Metering Pump still working.
In metric that's 80 ml to 20 litres of fuel.

Yes, I leave the OMP operating.

I'm designing a 2-way OMP valve that will use 2-cycle oil from a reservoir, when available, or from the sump when the reservoir is empty. But even with that, it is useful to have an additive in the gas to clean the fuel system
