I have recently bought a 72 F250 Camper Special with rebuilt 360. It will not Idle when hot and I am trying to get the carb and timing dialed in and can not find the timing mark on the crank pulley. Can anyone give me a clue. Thanks JD.

 

Put the engine on #1 cylinder and look carefully at the pulley. Use some white paint in the groove. To find #1 cylinder put a wood dowel down the spark plug hole and move the crank, by hand, until the piston is at the top. Make sure the valves are both closed. Did you do a compression check?

 

They're there, probably just covered by rust and gunk. Get up under the truck with some rags, carb cleaner, steel wool and some sandpaper. Clean the edge of the crank pulley with rags and carb cleaner, then do the steel wool and finally the sandpaper. Don't worry, you can't rub them off. Might take some looking but you'll find them after the pulley edge is cleaned up. Last step is to take a piece of kid's sidewalk chalk and rub generously over the timing marks...this gets white chalk down into the marks so they are easier seen with the timing light. Good luck and sweep for rocks under the truck before you start...you'll be under there awhile.

 

FE engines have a timing pointer, it may be missing, or the tip has snapped off.

Tube toothpaste, once it dries, can also be used to highlight timing marks.
