sounds like my carby. my carby wont idle below 2000rpm, it runs really rich and sometimes when i turn the car off it starts back up for like 5 seconds haha (it does really good key bangers because it runs so rich haha)

this is my carby,.... aparently a jap spec su dont no the brand name but i though hitachi was jap???

is this a crap carby????....... coz it doesnt seem to want to work properly. it back fires, it runs real rich , idle is very high. doesnt like full throtle and only works ok above 3000 ish. sometimes it floods itself if you start the car up for the second time or you either jam the slide up a bit... very strange...... i have tried using diffent tension springs on the slide and different dampaning fluids and nothin seems to work?????? any advise please
