In what position should the crankshaft be when a magneto is being timed to the engine? CORRECT ANSWER The piston in cylinder no.1 should be in the correct position for ignition to occur. This is normally about 30° before top dead center on the compression stroke. What is the purpose of a cold cylinder check? CORRECT ANSWER A cold cylinder check determines which cylinder is not firing. Run the engine for a few minutes at the speed, and on the magneto, at which it runs roughest. Shut it down a...
