I adjusted valves 2 weeks ago.
yesterday, I had extreme power loss.
I opened up the valve cover, and cylinder # 3 (front left of engine) had about 1/4" clearance on intake valve. It was firing out the carb, and pushing fuel/ air out of carb.
What would cause this? the "lock nut" was tight....
bent push rod? flat spot on cam suddenly? cam follower suddenly shaved off 1/4"?
