There are no timing marks, timing is correct when the flywheel key is in place, the flywheel is properly torqued and the air gap for the magneto is properly set

the best compression for a B&S is between 50 psi and 60 psi. if it's below 40 psi there is a problem with the rings or the tappet clearance (not letting the valves close all the way) but if it's smoking i would start with the rings...good luck

Andy, Hi, well I would start at the Starter myself, usually the thing called the "Bendix" spring jams up and stops it dead. Pull of the Starter, and power it up, off the unit. This will show you if it snaps in and out.
Sometimes a few judicious whacks with a soft hammer will sometimes free up the spring, if thats is indeed what's wrong. Anyway try that first. before any disassembly.
Make sure the Motor CAN actually be turned, by turning the flywheel, this should show you if the Motor is "Free" enough to move.
Also check ALL electrical connection to the starter. Use a meter and see if you are actually getting a voltage to the starter too. make sure your starter battery is good too.

SOURCE: Craftsman 42 inch deck mower.
That model number des not show up as a good number on the http://www.searspartsdirect.com site. Are you sure you have the belts on correctly? If it has 2 belts on the deck & 1 is not installed correctly they work against each other. Safely make sure that each blade will turn by hand. did you take the blades off? If they are too long by just a fraction, they will hit ach other, but that usually makes quiet a noise. Get your book out & systematically go over everything you touched or changed. It sounds like something really simple you have overlooked. you can go to http://www.searspartsdirect.com & enter a good model number & view all of the parts diagrams. Sometimes they are a big help, & at other times they just confuse you more:). Let me know what you find!!
