What size chokes are you running? If you want you 1.8 to have some low end grunt you should be in the 32 to 34mm range, also a 140 main jet is on the rich-end for a 1.8l engine to be running. Give us a list of your.

choke size

air corrector

emulsion tube

pump jet

when set up right the DCOE's should run with little fuss.
