"Just when you thought it was safe to go back in the water...." So I had kept the Corvair to check just a few more things. Paranoia pays off. It'd had a bit of a rough idle. Seemed to have plenty of power, but the idle was a bit rough. I was worried. I cranked it up and let the fast idle come down. Then I pulled the plug wires one at a time with my plastic pliers*. Sure enough, # 6 didn't have any difference
. Next, I pulled all the plugs and did a compression check. # 6 had no compression ( I had positioned the dizzy to #6 firing position). Next, I got a long air hose and rigged an extension to my air nozzle and plugged it down into #6 sparkplug hole (kind of a cylinder leak test). Hissing from everywhere
. Thinking, I put all the plugs but # 6 back in and re-did the test. No hissing and now air is coming out the tail pipe. Hope, hope, hope-hope-hope, that I just got the #6 valves too tight. Pulled the left valve cover (I still needed to make and install the stainless studs for this head anyway). Sure enough, the rockers for #6 seemed tight. I backed the exhaust off about 1/2 turn, and backed the intake off 1/4 turn. I went to pressurize the cylinder again, and immediately the crank spun as the #6 piston received air pressure and the piston went down (has compression now)
. Tomorrow, I make the studs, crank it up and properly adjust the #6 valves. I've said it before. I hate Chevy hydraulic lifters!
* The plastic pliers. I've had these for around 40 years. It has to be one of my favorite tools. Why? Because I don't know how many times during those 40 years these have saved me from getting the living crap shocked out of myself by a spark plug wire. That's what they were made for, that's why I bought them.
