Questions, not just for my own benefit, really, but...are you heating the wvo, what type of oil is it...hydrogenated soy or what...how are you filtering it/washing it and how's that going for you so far? Seriously I'm asking because maybe the air in your primary filter is kinda typical...mine is usually like 75% fuel at idle... and you say you normally experience problems in the evenings like when it's cooler then during the day...wvo is not all that viscous, maybe un-heated vo at lower temps is harder to pull into the IP, less fuel, more air....dunno, just a thought...and since I'm gonna go veggie myself I am curious about your system's symptoms...
