Alky FTZ 35.5s Die After WOT

[Superkarter]

I have a modded RZ on a Superkart that we run on road courses. I tried switching to alky using the FTZ 35.5mm modified mikunis that they distribute and have had fits with it. The problem is it will go like a bat out of hell off the line but as soon as I have to break throttle, I can't recover it. The engine just dies. As you know, starvation and flooding can present themselves through similar symptoms. So I've explored both. I went through the host of jets and tubes with little difference. It always dies when coming off of WOT. Yes, I tried running seperate high output fuel pumps--one to each carb----and that doesn't help either. Carbs are mounted so float bowls sit level to ground on FTZ manifolds. Does anybody make oversize alky bowls for Mikuni TM type carbs? Any suggestions?

 

Thanks and, keep killing them 'squitos with that sweet smell only a 2 stroke can make George
