Don’t throw your dough at another carb. I’ve got a carb shop just up the road in Youngstown. I can straighten things out and if you want mill the air horn off and blend it in. I can also recolor the body and replate the linkage if you want. Everything is test run and tuned before it leaves. And if you ever have a problem, we can talk face to face and I can even take a ride with you. Instead of waiting on hold for a salesman. Woodruff Carburetor Specialties 330-799-9479
