1984 626 Hatchback

[cyrusmaster]

Hello guys...

i need ur help..currently i'm using mazda 626 hatchback... codename GC. i think same as ford sierra.

my prob is when trying to start the engine, the RPM gradually stable. it goes up to 2k for a while. after that, straight down to 1k and eventually, engine stop running. it keep going like this.

after start many times, idle RPM goes around 1.5k. when shifting, need to press the accelerator at least 2k. otherwise, engine stop running.

some people advice to add grounding wire, clean the carb but nothing change. before that i replace my fuel pump. it sound 'tik..tik..tik..'...maybe pumping the fuel in.

for info: my engine is 1.8L NA carb.
