Apache running too rich
I have a 58 Apache step side, column change 235 with twin Rochester B carbs and Offenhauser inlet manifold. Ever since I've had the truck it has always run too rich. It starts and runs fine, but the plugs are always black. These are the things I've done recently to try to fix it but with no success -
1. Checked fuel pressure from electric pump 2. Adjusted float levels 3. Fitted two new carb kits 4. Got recon back carb to match front. 5. Checked operation of choke. 6. Removed air filters and replaced with aluminium mesh to let more air in 7. Reduced jet sizes from 50 to 46. The jets are down 4 sizes already, but is it possible that they should drop another 4? I can't think of anything else to try. |
