Re: Sparks from under the flywheel...
There was no 1972 60hp. 1972 was 65hp, 1970 & 1971 were 60hp. They were totally different under the flywheel. So, if we can safely assume it is a 1970 or '71 60hp, I'm going with boobie's theory. Distributor cap or plug wires. The wires often arced out where they exit the cap.
