Flat spot on gas

Hi all,

I have a NC Fairlane I6 that's duel fuel. It has an omvl r90 gas converter with ring mixer. My problem is the car has a flat spot on gas at around 4000rpm. When I floor it revs will rise to 4 grand and then just sit there for a couple of seconds before they keep on climbing. Would anyone know what could cause this flat spot and what should I be checking?

Appreciate any help

Cheers,

My car did that a few times last night, dunno at what revs, and it only seemed to be about 1/2 a second of flat spot, but very annoying.
