OK...so we did camoit's snap rev trick...(by the way it is a mikuni carb.) husband was playing around and we unpluged the vacuum hose on the air control valve on the air cleaner intake. I don't know if it was the snap rev trick or removeing that vacum hose but it is now runing about 95% better. only does the stuttering at the upper end rpms. cruised out to get the boy at the bus stop and it drove fine as long as I didn't rev it up to high.
Now the question...the hose we disconected off of the air control valve goes to another valve? inside the air filter housing and another line goes from there to another unit with a bunch of vaccum lines on it that is down under the carb on the intake maifold. What is that piece called?
