Farmall Cub

i have used a spark tester on a car before but im curious about using one on the cub. can you connect it and crank the engine with the hand crank to test for spark or will i need to use the starter. the only reason i haven't tried with the starter is i'm unsure whether it operational or not? thanks allot

You can check the spark hand cranking but you will probably need two people. One to crank and one to observe tester.

The tester works fine on the Cub.
