for a while now i've had this dodgy acceleration and i've tried everything i can think of so its time i ask for some advice.
set up i have is blue 308 running a fresh rebuilt quaddie jetted for 308(from sues carbs, i assume they jetted it correctly) with a cable throttle linkage
what happens is if i give it about 50% throttle it accelerates nicely.
if i keep the pedal going down to 100% WOT it bogs and when i back off to 50% again the acceleration picks up again.
what i've tried so far;
-made sure that the pedal when pressed to floor opens carby 100%
-made sure the carby is nice and snug to the inlet manifold and i used a new gasket between the 2. im pretty sure ive blocked all vacuum holes that aren't in use.
-quite sure i'm not getting wheel spin as i'm running an lsd with tyres that are quite chirpy when they do spin so i would hear it.
-clutch and pressure plate are quite new, tried the old handbrake on and pull the clutch out and it seems to be not slipping at all
-i'm hearing no grinding or crunching in my w50 and the box was just opened up and had new bearings put through- gears were great and the problem also happened pre-gearbox rebuild
-a mate of a mate of mine with a performance shop set the timing and set up the quaddie so i assume that's right as he's a Holden man and knows his stuff.
Ok so any ideas??? It's really giving me the sheets
