Hello folks. I've been reading through the different posts on various carb issues, and have one also. I just bought an 86 LX from my boss (for 100 bucks). Drove the car home, and had to put my foot to the floor at each stop light to keep it running. Got home, found the choke spring was disengaged, so I fixed that. Now the choke opens, but the car idles extremely high, and rich (I smell gas while driving and my tailpipe is black). I've tried adjusting the float screw, and the idle screw (kind of a pain to get to, isn't it?) and it seems like I'll get the idle right, but then after awhile, the problem will return.
I'll be replacing the following tomorrow:
fuel filters
engine coolant (with flush)
air filter
possibly the carb gaskets since the thing is hissing like mad when the air cleaner is off
I've checked all the vaccuum lines and they seem ok. I'm reluctant to replace them since they are numbered.
I know the a/f mixture screw could be adjusted, or it could be a waterlogged float. I was just wondering if anyone else out there had this specific problem and might be able to save me a bit of money/diagnostic time here.
Oh, and the car acts a little like it's still choked when I take off. I know the choke is opening....I've checked it about a thousand times already.
I can tell this will be a great little car once I get everything squared away. I just don't want to melt my Cat running it too rich. I would also like to avoid messing with the A/F if possible....Dad always told me to leave that damned screw alone unless I had tried everything else already. Plus, taking the carb off to get to it looks like it might kind of suck.
Oh, and does anyone know if there's any way to tell for sure if the motor mounts are bad, or if the wierd idle is causing my car to shake at the stop lights?
Thanks for any help you guys can give me. I'll be doing a few things to this car and will try to post pics.....
