Hey there, Joe -

Yeah... it could be. As I was revving it, I thought it could be that too, but it looked so diluted compared to other smokers I've seen that I somewhat ruled that out... but in the end, that may be the case. At high rpms, it almost looked like a 2-cycle exhaust that is too rich - rather than an actual smoke system. At the lows, it was a nice dense white puff. Since the pump is running off the crankcase pressure, I was hoping that it would keep in proportion the amount that would be required by having the pump speed increase as the pressure cycle speed increased. But... still experimenting.

Thanks for the note!
