Well,
taking the advice given here, I've started adding distilled water into the air intake to steam off the carbon build up I get from running WVO at a bit slower than 650rpm.
I quickly got tired of going up to the gen and dropping in a tablespoon every hour or so, and now have learned that it's better to have small amounts regularly going in. So, I grabbed what was available and built a drip system using a few cheap parts from a garden irrigation system.
A vinegar jug, which is a little stronger plastic than the typical milk jug easily took a barbed end to add the 1/4" tubing. Then a 1/2gal per hour drip nozzle (the slowest one I had on the homestead) seemed to still be too much water, as I'm told I want to equal fuel consumption. (I *think* I do about a liter an hour, so that's twice as much)
So I went and bought little shut off valves (image attached) and since they come in packs of 2, I was able to use one to dial the drip down to a bit less than a liter an hour and then the other one is the on/off switch I can turn when the engine warms up. (indicated by the yellow arrows in the attached image) [sorry for the blurred image. I took the photo while it was running]
Drilled a simple hole in the filter to slip the tube through. the tube probably ends at the elbow of the air inlet.
By hanging the jug above the inlet, I have a very simple gravity fed system that's easy to monitor and easy to refill.
