Sheet Metal Tube Under Carb??
If this tube is missing maybe this is why these engines have such terrible uneven mixtures between different cylinders front to back?
The tube would force all the fuel/air mixture to the floor of the intake.
This does 2 things.
1. Forces the mixture against the hot metal base of the intake which is bolted to the exhaust manifold. So this would help vaporize the fuel for better combustion.
2. It would also keep the center intake port from thieving the majority of the fuel since it's straight across from the carburetor. Give the 2 end ports a bit more even mixture?
Here it is installed;
Here it is with the tube removed;
I do see that manifold has 2 squares cast into the top that my intake does not have. This was supposed to come off a 1947 KB5?
Is anyone running these?
Anyone have a part number?
