I have 85 brat got a couple months ago,been working on it ever since.It starts right up runs pretty good,I can drive it 5 miles or 50,But when I shut it off, run in store or what ever, get back start it up it idles fine - so as you put power to it it wants to die push gas pedal a little more ( or feather the pedal )you can get higher rpms to get it to go. Then using clutch as to get it going much like a bucking bronco,Drive a little maybe a few miles it goes through the flat spot an in to higher rpm an all of the sudden it starts running fine again??? have removed tank cleaned an sealed new filters-had carb rebuilt ,new cap rotor- module- wires- plugs-egr-pcv-coil-?timed-not running hot So What have I missed? So far it has always started fine and runs good UNTIL I stop and then want to go again.
