hmm, was just thinking, i cant get like 100% throttle as it cuts like theres not enough fuel,

but..

it's making 10psi boost and maybe trying to make more, so it's possible that it's trying to make more boost but there is not enough fuel/pressure to do so and therefore it is cutting

does this sound likely?, i think it could be my problem, which means i need to create a leak, probably just wont seal the lid on the carby box for now
