Went down to the parts store today.
checked the book from behind the counter.

The gasket kit i bought suits my carb model.
DCG306.

Recarb brand rebuild kit, HT05L which replaces HT-412L or written in pen GC005

Ordered a second kit to try another gasket.

I everything is clean, so i have no idea why it would leak fuel when i press the accelerator pump.

Adjusted float and needle was changed to the new one in the kit. (also tried with my old one)

Replaced the PCV valve, now have new crank case hose and rocker cover to air cleaner hoses ordered from Nissan, $111 later for two hoses.

New exhaust/intake manifold gasket.

tried with the old PCV hoses connected and clamped, tried with the PCV valve covered by a rubber vacuum cap to see if anything is leaking there.

New vacuum hose to the distributor.

I have cleaned and air guned every single part, plus the new throttle chamber comes with new idle screw and was genuine Hitachi new in packet.

and still my car randomly stalls at when stopping at intersections. AArgh!
