It seems quite unlikely. I wonder what compression checker you are using? I had a buddy who was bragging about his compression, all 80/80. Turned out he didn't know about the needed orifice in the compression checker.Is this possible?...

Steve,
Your post (#3 in this thread) is titled .060 orifice.
Someone correct me if I'm wrong but I think it should be .040
AC 41.13-1B states:
"Engines up to 1,000-cubic-inch displacement: 0.040-inch orifice diameter, 0.250 inch long, 60-degree approach angle.
Engines in excess of 1,000-cubic-inch displacement: 0.060-inch orifice diameter, 0.250 inch long, 60-degree approach angle."
