Is this a common problem?

[10.5]

I've been running E-100 for over a year now. I did all the upgrades to my carb myself, but it seems to allow fuel into the motor when it's sitting. I've been having to kill the fuel pump and basically run all the fuel out of the bowls to keep this from happening. Is there a common issue regarding this?

The carb is a 975 race demon w/ a pro systems base plate, QFT metering blocks, 97/98 main jets, 23 hsab's.

I did drill the IFRs (possibly too big) to get the lean spot out of it...before doing so, it would go lean when getting on the transbrake and not come up on the converter quickly. Now, that issue is resolved.

I dont think that is fuel specific, but I dont know. Mine did that on gasoline. havent notice it on the E85 yet, but I also havent been checking.
