I've had some issues with idle with my mantis hobbit.
Up and down, really annoying. When up, I could lean it to the side and boom, back to low.
It was from pooling between the Reed block and the intake.
I like to attach my DIY intakes to the original intake manifold because it gets the intake away from the frame, unlike this fucking mlm 24 I just tried.
Now that's a dumb design. Never make an intake that will hit the frame when you have suspension, duh.
As far as where it pools...
It's a bad design, Reed block angled up with reeds opening on top with a big ol wall ready to pool fuel like a motherfucker.
So I cut the modded stock Reed block up to flow better and made the flow a consistent downward slide from the carb. Not the steepest, but good enough.
So, here it is. I like it. Trumps gonna build a wall, I'm tearing them down broS
Ps, this is the triple stage Reed setup. boyesen style with Reed springs.
