Hey, Terry, long time no see. First, check for spark. Pull a plug wire, insert phillips head screwdriver in the end, and hold it 1/4" away from engine iron, and crank the motor. Should see a hot, blue spark jump the gap. If no spark, unplug the wires from the coil and the black sqaure thing on the coil bracket and spray with wd40, then wash with white vinegar to clean up the terminals, and do the same on the distributor. Remove the air cleaner and see if the element is damp. If so, replace.

Report back.

Are your folks still on the lake?
