Does it have a provision to open the secondary's with a set screw on the base plate? You might have to remove the carb and look. Is the choke linkage all free? I had a issues once where it was bound.
I don't recall, but I am going to turn it over to the pros. I just called a shop here that does hot rods and they told me to bring it down there and they would fix it for me. I just have to have it towed there and they would'nt quote me a price.
Which is ok, I am willing to pay rather than me messing something up. I just hope I did'nt screw anything up yet.
