Check out the valves today-my #6 intake tappet loosened so had too much clearance, once I adjusted that the loud knock went away. While I don't have 3 ft [thank god] it was a good 6 inches on a good fire. My fuel distributor is just purchased from SpecialTAuto. The last one started making loud shrieking and suddenly raw gas was POURING out the tail pipe. Once I got the new one on it took half an hour just to burn all the fuel soaked in the muffler out-looked like my old 66 thunderbird with a half blown 390-smoke everywhere. Nonetheless, I know the FD is good to go. To help in my future problems I got an order in with JC Whitney for a Bosch CIS K-Jet fuel test kit, only 56 bucks! I'm very hesitant with touching the CO now-now that my FV is running tip-top; and the exhaust smells fine with no color. I was under the car today after pressurizing the system, I looked all over the accumulator and lines there is nothing leaking, looked at the fuel filter and that isn't leaking. As I mentioned the pump check valve is new and the boot and lines aren't leaking so I'm a bit baffled now. There is definitely a smell of fuel around it though, tomorrow I'll jump the pump while looking. I did the tune up weeks ago, and pulled #1 & #6 plugs today to determine TDC and stroke; +4s look like number 3 on John Hervey's spark plug Analysis chart-carbon deposits. After those 2, I checked them all and they're all like this. I'll check timing again tomorrow just for kicks. As is now, car sounds good with good power so I'm happy. Just a few more things to do before [I hope] it's back to running like it should.
