...I have read some post about the Eddy starving for fuel when using an oversize tank with the pet-cock mounted at a lower level than stock. When the fuel runs low there was not enough pressure to fill the float bowl at full throttle.I think this has been corrected. ( some people had installed a small electric fuel pump.)I have had zero problems with mine (IMS 4g tank), and I love its simplicity. I hate fudging with jets when I can be out That's what I thought at first too (was running an IMS 4.5 gallon tank). But it has the same problem even after trying the stock tank, and now I'm running an IMS 3.2 gallon tank.
