L28 fuel problem

[psyosphere]

Thanks for the people that helped with my last problem with my L28 engine not have any spark.

i have it all up and running now but im having a fuel problem, it starts and idles well till i give it a nice long rev, then when i try a rev it again its like the fuel is starving and the carbie can't refill quick enough (im using a weber 28/36dcd carbie).

could the problem be the standard electric fuel pump has'nt got a high enough flow rate or the fuel pump is about to die?? or could i installing a second standard electic fuel pump to pick up the folw rate more??

also could it be that i have added 2 extra fuel filters on the fuel in line and the return line??

 

this never ends....
