hi im starting to get annoyed now with my r5 gt, for months its been having running problems hesitation, lumpy idle and hunting, bad starting and will only idle when running choke at 3000 rpm till warm then letting choke off, and fouling the plugs. things i have done:
rebuilt carb with all new gaskets, checked carb base for flat
set dizzy drive gear right, as was tooth out
new leads,dizzy cap and plugs
swapped aei unit
replaced all vaccum hoses and checked all for leaks
cleaned all jets about 5 times
set mixture screw to 2 and half turns
set acc pump to 5mm with drill
the car is now running better, not hesitating anymore but the car still idles lumpy and wont idle untill warm , rev the car and when you let off runs really lumpy for a few seconds then returns to normal which is still slightly lumpy, when fan kicks in car drops 200 rpm. anyone any idea what else can cause lumpy idle. the engine was rebuilt could it be timing slightly out? also could the ignition timing be right but one of them bodge tdc sensors fitted or would this not affect idle. also im getting a rattling noise from around the turbo or flywheel area as though the car is going to stall, cant pin point it, any ideas welcome as its getting really annoying now thanks
