Problem with m10b18i

[AlexE30]

Hi there folks , i recently did a swap on my e30 m10 carb engine , to an m10b18i , but got some problems .
Good friends , as you know did swap for b18i but I have a problem I can not solve.
When I give the engine key start soon and has a stable idle flawless, but when it rises slightly accelerate rotation but it seems "dry" and almost goes down .
Ja methyl new spark plugs, cables all new, distributor cap and rotor and the problem persists.
When I swap also put new gas pump, this problem can not take the car from the garage , when i drop the clutch reving the engine almost diyes..
I´m sory for my english
Hugs
