I just have to get the cart fillin part down. What is folks opinion once a cart gives a burnt taste dont reefill>?
I guess there's all levels of burnt. When I've tasted oil getting burnt I've backed off rather than pressed on. It usually clears back up, supporting my current theory that the burning happens at the preheat stage, not the vaporizing one? Once the cooked oil is flushed through (hopefully without further roasting) fresh oil follows it IME. I see it as like when you change concentrate types, from burnt to fresh?
The outside of the carts low down gets much hotter when this happens seems to me. No way around the idea that the oil inside, near that first heater, is hotter still. But like I said, I'm sure guys can get in deeper than I do, could well be different for them.
I'm not sure the power balance between the heaters scales all that well.
Consider a swing or nail, all the oil that gets to it vaporizes just fine, I think the same happens at the main vaporizer in the cart. Oil that makes it up the wick finds more degrees than 390 and it 'flashes to steam' (vapor in this case) on the spot. I also think small local pressures from that boil off control feed rates and also 'pumps' the sludge to the surface, making the 'scab' grow on the outside, not from the inside out. No burn. The burnt part comes from cooking the oil
before that?
