My old (1960-70) Sears Suburban, 12hp has been very slow to turn over ever
since I first got it about 5 years ago. It usually starts but you'd think
it hardly turned over once or twice very slowly. I replaced the regular
12V tractor battery with a car battery but it still turns over slow. It
has the old belt drive starter and I also swapped it with another
machine - still slow cranking. Any ideas as to how to get this sucker to
spin over better ?


Use heavier battery cables. Make sure you have a good ground connection.
