g'day all,

 

ive got a ke70 panel van with a worked k4, (cam, ported, dual valve springs, oversized valves, strethend bottom end, 4-1 extractors ans 2'' exaust)

 

until just recently ive been uning a stock asian carby on it and getting 76.5 rwhp @ 7900rpm. ive since put a 32 / 36 webber ontop of the beast, and power seems alot better but taking off or anything under 3500rpm it is really unresponsive and lacks power there. ive been told a few reasons for this 1 is that the carby is to big, 2 with the oversised cam and all the port work that 3500 is were everything works with each other and makes the power.

 

what i want to know is it just something i have work around or could the carby be to big

 

cheers, ash

Gday .Do you know if the jets have been jetted down? cause a standed 32/36 is to big from what i have been told.

from what i know it has'nt been touched, just put straight in

thats a pretty worked engine i wouldent think it would be very drivable under a cirtain rpm

 

but yeah rejet the carbie would be ur best bet
