hi i posted a thread on here a few weeks ago, i have been having problems with getting my gt turbo idling correctly, the engine has had a full rebuild, new oil cooler, alloy radiator and intercooler, new turbo, everything basicly. the car wouldnt idle untill warm, had to run the engine on choke at 2500-3000 revs untill fan kicks in half way temp. then the car would idle but lumpy and when you tapped the throttle would hesitate and cut out. i then rebuilt the carb all new gaskets, set acc pump arm to 5mm with drill bit, cleaned all jets, im running a 120 main jet i have t25 turbo and headwork, cam.the car wouldnt run at 1000 rpm unless the mixture screw was wound out 5 turns. since the carb rebuild i have set the mixture screw to 2 and half turns and it now idles but still slightly lumpy and doesnt hesitate when you press throttle. however it still doesnt idle untill fully warm and there is a strong smell of fuel seems to be coming from near the fuel pressure regulator,and its still slightly hunting. i hav checked for all leaks using carb cleaner and fairy liquid and no leaks, changed aei unit. anyone got any ideas as its doing my head in. went round to a lads house near me who has a gt turbo hadnt been run for a few weeks and his cracked up first time with no choke and ran perfectly.sorry for the big essay but its so anoying lol what can a faulty fuel regulator cause?
