how old where you when you first work on a car

ha now you are changing them from points to electronic......
at 16 i was trying to stuff a 396 into a 6 cylinder 4dr chevelle never did finish it
i painted the valve covers and baked them in the oven ....mom was not happy ..boy did that stink
I used to set the points on lawnmower engines with a cereal box flap, after I sanded the flywheel with sand paper and filed the points with a fingernail file. At 10 I made "free" riding mowers into go-carts by changing the pulley size, and putting any motor that I could get for free and get running.
