1982 Daihatsu Charade 4 cyl Front Wheel Drive Automatic

It's actually a 3cyl . .I just HAD the engine mounts replaced,so it's probably not them causing it,but I can't seem to get the idle to relax and smooth out . .it's always 'chuggy' . .I have checked the vacuum hoses ans they seem ok,and it runs well at speed . .there seems to be a 'harmonic' factor at plat here too,as at certain points in the RPM range it nearly vibrates the car to pieces . .the only way I am able to drive it is to keep the idle super-low(around 600) . .the thing is,too,is that I am adjusting the idle by metering the brass knurled screw at the rear of the carb . .the idle stop does nothing . .I'm probably f***ing around with the mixture,uh? The plugs and leads are in good nick,but I haven't checked the fuel filter as the enging zips in the higher RPM range . .the exhaust may have a tiny flange leak as it's a bit 'boomy' . .I dunno . .

hello dodgy_dogg

I am having the same problem with my charade too.. i replaced my fuel pump regulator, air filter, tried many settings of carb for idle, no hose leak, and my muffler/exhaust is has a noticable loud unfine sound.. i also notice it turned to consume fuel alot now. tremendous fuel consumption for a 3 cylinder. i can actually compare it with my 2.0 nissan bluebird.. do you have the same problem too? because my mechanic told me, it must be my carburetor that i need to replace seends it a very old 1, even though i had it overhauled months ago, the mechanic says it might turned out to be a faulty carburetor. i havent replaced it yet since im a little depressed already with this issue.. did you happen to fix your problem already? what did you do? every one that has any idea. please help.
