1952 8n idles perfectly but only with the choke 1/2 way out. It's been tuned up and starts easily and continues to
run but a little rough. Carb was overhauled last year. I thought something must be plugged up. Took carb off and
soaked it in paint thinner. Sprayed carb cleaner through all opening I could find. All seems clear. Put it back on
and it acts exactly the same way. I started trying to adjust with the front adjustment screw all the way in then
backed out 1 1/2 turn. The side adjustment screw- all the way in then 1 turn out. Then I adjusted the idle down to
a slow idle. Then adjusted on the side screw. It makes almost no difference. Seems to run a little better with
that side screw all the way in. It is a Marvel Scheibler carb. What am I missing?
