My 51 truck has a 1961 235 in it. It has been rebuilt including the carb. On the road it will have a slight miss about every 2 miles or so. It doesn't seem to bother the way it runs but it is annoying. I can pull the choke out about 1/2" and it stops. Seems to me a carb. adjustment would take care of this,would it? This 1 barrel Rochester only has one adjustment screw on the base next to vacuum line. I don't want to try this if it will not help since it runs really good other than this. Any ideas? thanks mh
