ScottyHOMEy said: (quoted from post at 18:56:00 09/06/09) Getting it to TDC on #1 -- with the obvious proviso of putting your thumb in the hole to make sure that you're coming up on compression, top it out by eye and then use the trick of putting a stiff wire or short screwdriver in through the plug hole to make a lever of it. When the outisde of your lever is at its lowest, the piston is at its highest. Ta-da!!
To fine tune/verify that with the mark on the flywheel, take a toothbrush ( a similar-size brass or sttel brush is better) with your favorite solvent to find the mark, then hit it with a squirt of brake cleaner to dry it off and mark it with some paint. The index will differ according to what kind of half-moon cover you have under the motor at the front end of the torque tube. If it is cast, there is a nub/fin on the inside of the casting. If it is stamped, the vertical rib stamped into it is your index.
If you are feelin' wimpy, this is a great opportunity for personal development, and you'll be a better man for it (JK!). If you've got it close enough to find the mark and paint it, it shouldn't take more than a dive or two underneath, with trips back up front to the fan in between to turn the motor to get them lined up. There is nothing wimpy or unmanly about removing all the plugs to make the motor easier to turn. ;8^)
OK, I left my self open to the wimp bit. :-P
I guess what I'm asking is there anyway to verify the high speed advance timing (30 deg ATDC @ WOT)? The only way you can do it is with a ATDC mark and a timing light.
Now if the distributor is set correctly at slow speed, it should be right at high speed too if the distributor is working properly.
Rummaging through my manuals I found the the book that came with the distributor (1973 is when it was upgraded from a mag) and it sounds like you time it at TDC statically, no timing light option.
At TDC, with the switch on you should see a draw on the meter (points are closed).
Oh and as far as indexing, did that twice today. Set the valves, after reinstalling the head, warmed her up, re-tourqed and did it all over again. I'm almost a pro now! :-P
I guess if it's running bad at WOT with the timing correct then there's something wrong with the advance.
I'll take a closer look tomorrow.
Thanks guys,
K

Today's Featured Article - Choosin, Mounting and Using a Bush Hog Type Mower - by Francis Robinson. Looking around at my new neighbors, most of whom are city raised and have recently acquired their first mini-farms of five to fifteen acres and also from reading questions ask at various discussion sites on the web it is frighteningly apparent that a great many guys (and a few gals) are learning by trial and error and mostly error how to use a very dangerous piece of farm equipment. It is also very apparent that these folks are getting a lot of very poor and often very dangerous advice fro
