Right guys, car ran fine at 13psi, had a smooth consitent idle at around 14.1
Had off boost driving between 13.5-14
WOT saw around 11.9-12.4 area
Wanting more boost like most, so took carb off, left main jet alone, drilled 2nd stage to 1.2mm to start with and fitted a 1mm AC jet. Other than air linning the 2nd stage bit out after drilling and a spray with carb cleaner the carb hasnt been touched. The 2 gaskets i disturbed (2nd stage bit, and carb body bit) where all ok so refitted.
Put carb back on, and mixture screw, idle screw was in same position as i took off etc it started up ok but idle was abit low and on idle it was very lean going 17 and then off the reading, no biggie i thought it just needs adjusting, got it down to around 14.5 with the mixture screw wound right out, did a run in it and as soon as it got upto temp it wont idle and dies everytime im off the throttle. Tried adjusting the idle screw aswell no good, also removed the idle jet thing, the big screw on drivers side and made sure it was clear, no different.
Iv seen a 5 with no mixture screw atall in, just pluged up and its exactly like that, no idle, dies when off throttle. Obviously this put a end to any more fueling testing. Also i have a turbo from cr turbos, and im about 3 threads away from the end of max adjustment but boost hasnt really inscreased, actuator starts to open at 18psi when tested, but boost gauge in car wont go over a bar, boost leak?
with carb like it is, and boost set 18psi actuator, 14psi boost gauge im geting
no idle, 17+
off boost driving seems to vary 14-15
on boost it was mid 10's so very rich? and feeling very flat, I need to get boost up to cover this right?
Also my 5 with a scorpion with standard carb drove very well, no real pops on overun, now on over run thats all it does, pop pop pop pop
