Question about Honda Civic
Step daughter has a 1989 honda city with the 12d engine and a carb , hesitates at intersections and stalls ,
it haS A slight miss till about 5000 revs ,at about 3000 when driving up road you can feel it surging , is more previlent when engine gets warm and seemed worst when raining? . often it stalls as you are coming off a roundabout . The float adjustment screw speaped a bit of petrol so i chucked some stuff in recess to stop that . but not sure if letting to much gas in bowl would cause problem float seemed to be set to high, can't find obvisous vaccum leak gonna try a bit of ether tomorrow. looks like some one had done some work to carb before with new lookin gaskets but the previous owner said it had problem for a while hmmm. anyway any ideas ta james
This is what id do...
Id remove all the spark plugs and inspect them.
This is how i diagnose fuel/spark suspect issues.
Buy doing this you will be killing two birds with one stone.
1.See if the plugs have been firing correctly.
2.Are the plugs fowled or are they running to lean?
If your fuel/air mixture is too lean it will not ignite properly on the power stroke. So it may miss one power stroke until the next power stroke comes along which would add more fuel and then ignite.
Something like this will be causing that funky stuttering missing that you have described above...
And id say if it comes right over 5000RPM thats probably because the carb your running is a two barrel or similar and the second butterfly will open roughly about then and be providing that extra mixture.
I encourage you do just do a bit of investigating you will eventually find your problem.
I wouldn't go buying random parts and just throwing them on until you no what actually needs fixing other wise its just a stab in the dark...
Hope this helps let us no how you get on...

Try the coil pack... pull a spark wire at a time... note any change in how the motor runs ? ... plug it back in and move on to the next one
