17.5 hp 42 in. Deck Lawn Tractor – CA Model

I inherited a Sears tractor from the neighbor. The 17Hp B&S engine starts and runs, but we get smoke from the front pulley under the engine when the clutch pedal is disengaged, and no expected movement of the tractor. Is there a better troubleshooting manual than the stock Owner’s Manual? If not, what are the obvious problem areas to check? The mower free-wheels just fine when you push it from your neighbor’s house to yours…

Thanks, Rob

This could be caused by not enough air getting into the system, not enough fuel getting into the system, or the fuel/air mix not burning well enough once it gets into the cylinder. It`s probably a clogged air filter. Could also be a clogged fuel filter or a bad spark plug.
Usually, manual cars will stall because the driver has let the clutch out too quickly. This means the `revolutions per minute` (RPM) of the engine has dropped too low and the engine has stopped. You`re less likely to stall if you release the clutch slowly.
There are several reasons a Craftsman lawnmower may turn over but not start, with the most common ones including the following: Lack of fuel. Dirty air filters. Electrical issues in the ignition system or the starter motor.
Your Mower Won`t Start:

Other possible causes include: Loose, Dirty or Disconnected Spark Plug in Your Lawn Mower: Check it out, clean off debris, re-connect and tighten. Dirty Air Filter: Clean or replace. Fuel Not Reaching the Engine: Tap the side of the carburetor to help the flow of gas.

Sticky or stuck pedal

A clutch that sticks can cause grinding noises or can keep your vehicle from going into gear while a clutch pedal that is stuck to the floor renders your vehicle undriveable. If either of these situations happens to you, a trip to your mechanic is in order.

For instance, if a driver takes their foot off the clutch too quickly while stationary then the car will stall; taking the foot off the clutch slowly will stop this from happening. Stalling also happens when the driver forgets to depress the clutch and/or change to neutral while coming to a stop.
Tractor may be starving for fuel.

The fuel tank can develop a vacuum. This could cause fuel to stop running to the engine – causing it to stall. If this is the case, give it an hour or two, and the tank pressure will reset and equalize. Then the tractor will run again.
