So, I got my engine running!!!!!!
A friend came over, and we played with it for a while. Discovered that the jumper cables that I was using to provide power to the starter were shitty (they would drop so much power that a new, fully charged, battery could not drive the starter to turn over the engine with the plugs in). Got new better wires, and it spins like a mad man. But my timing was off. And Ross had to go home. And I had to feed the baby. So, I walked away for it for a few hours. After dinner I had a window to play. Off to the garage I go. Reset the timing. Take out the plugs and run it or 30 seconds to build oil pressure. Put the plugs back in, turn on the power, and IT CAME TO LIFE! Accriding to the tach I wired up, the carbs idle is set too high, as it was idling at 2000 rpm. Also, with the eurorace header and the turbo muffler it was loud as hell. I called Dr.Evil, and let him hear it. Then I shut it down, as I did not want to piss off my neighbors by running it 20 minutes to break it in as they are eating dinner. I go in to find the video camera, that my wife then admits that she has lost. Brand new (got it so she could take vids and pics of the baby). My luck was starting to turn for the worse. I realize that I am starting to get mad at her, so I go back out the garage to start the engine again, as I feel that will make me happy. It starts. Sounds good. Suddenly it is all wobbly and loping, and I shut off the power with a quickness. The damn squirrel fan has come loose, and impacted the top of the engine surround. Okay. So I torque it down, and start the engine again. Loping and wobbly so I quickly turn it back off. Take off the front tin, and take of the fan. turns out that I have broken the centering pin. Sheared it off right at the hub. Lovely. until replaced, I have no way to get it centered. I pulled off the spark plugs to lower compression, and ran the starter. It purred. The pistons did not make any scraping, tapping, or clunking noises that would lead me to believe that they (or their new rings) broke somehow. At this point, my baby was screaming. I mean this in the figurative sense (my soul and my engine) and in the literal sense (my 13 day old infant.) I cleaned up and went back into the house, defeated. I do not know if I forgot to torque down the bolts to the squirrel fan, or if they came loose on their own. Either way, it has put a serious bummer to what was shaping up to be and EXCELLENT evening.

It sounds like people are talking two different fasteners, here. One is the jam nut on the valve adjuster. The other is the nut on the stud that holds the rocker shaft onto the head.
I believe that the rocker shaft nuts are M7, one of few fasteners on the car that take an 11mm wrench. (If they take a 10, then they're M6.) I forget the pitch. The nuts are not self-locking fasteners, as far as I can tell. Those should be torqued when the particular cylinder is at TDC and both rocker arms are slack. If you try torquing them with one valve open, the spring pressure won't even let the shaft seat against the head by the time you get to 10 lb-ft! (BTDT.) --DD |
