OK, got to spend a few hours out in the garage this evening, here's what I have to report. Great spark to all eight cylinders. Buddy of mine has a cool little spark tester. Nice and blue, easily bridging 3/8". I tried to disconnect the throttle linkage, but the starter wouldn't engage. Not sure why? Hooked the linkage back up, engaged fine. Does that linkage somehow act as a ground for the solenoid? accelerator pump squirts fuel just fine. Float/needle and seat seems to be working.

Completed compression test and lubed each cylinder. Numbers are as follows:

#1 7psi
#2 50psi
#3 45psi
#4 5psi
#5 2psi
#6 3psi
#7 5psi
#8 10psi

Not looking to good, Wet test yielded absolutely no change, so I'm thinking maybe stuck valves? I've heard some people say to put ATF down the carb throat and spin it, to get them free. Not sure about that. Mebbe put some in each cylinder and let it sit for a week, then try turning it over. If it doesn't improve compression then pull the lifter cover and look to see if valves are touching the lifters?

Any advice on how to proceed?
