Thanks to all for the thoughful replies.
Oly: I just can't believe that the carb would screw-up right after I adjusted the valves. The engine was rebuilt about 4K miles ago and it definately has solids. I am however looking for some hydraulics for this monster as I type. If you have any or know where I can get some at a reasonable price please advise.
When the weather clears (Friday) I will go back out there and adjust the valves AGAIN at 6 & 13 but everybody I talk to tells me a different setting. The guy who rebuilt the motor looked up the hot setting at 8 & 16.
At any rate after I reset them I will check for spark on each plug but it would be very strange for the spark to quit right after I adjusted the valves.
