Yes you are correct. It sucked the fuel tank dry pretty quickly. But I'll be tweaking it some more.
I have been a bit afraid of the thing, so I have been approaching the needle adjustments with a lot of caution.
I run one of those (the standard MVVS58) in my Top-Flite Giant P47 on a stock Pitts muffler and spin a 3-blade Xoar 24x10 prop
When tuned well, it spins that prop with great authority
These engines are very user friendly, both to tune and operate
