Switching topics, the brass fuel float in the fuel injection unit had a leak and had been filling up with gasoline. When the float doesn't float the car doesn't run. This float has two halves that are soldered together. After a couple failed attempts to repair the old soldered joint I removed all the old solder and resoldered with new. The FI unit is back together and it's much better now.
Changing topics again, mechanical fuel injection experts recommend calibrating and tuning our engine using an air/fuel meter. Sounds good to me. Here I just finished welding the bung for an O2 sensor onto the drivers side side pipe. Don't worry, this is the reproduction side pipe, not the original one.
The meter was installed in our make shift dash and it works great. The optimum reading would be 14.6, that's 14.6 pounds of air to 1 pound of fuel. The reading you see is a little rich but it was taken at idle. We hit 14.6 when the car is cruising down the road. Our Corvette currently has 108 octane racing fuel in it but it will soon be changed to pump gas. When that happens we will retune the engine using our new gauge.
