Re: 64 McCulloch 7.5hp low profile spark plugs

[slim60]

When I started collecting I saved one of these from the "chopper" for ten cents a pound. Then I paid fifty bucks for a parts motor and got two water pumps (it needs both to pump), a shift dog, and a hood to get it running good. But I never ran it on my boat because it had a less than 15" transom length. McCulloch was into racing (gokarts etc.) so this one was pretty quick, in the tank. Pulling the powerhead wasn’t to bad with 1/4" sockets and long needlenose. I sold it for what I had into it plus a 60’s Chrysler 6. I told the guy to make sure it was submerged to the anti-cav plate to cool. He called me back and said it blew up and bought back the Chrysler that only needed a primary wire and was a very smooth runner.
