First check the oil, not only the level but the smell
if its overfull and it smells like gasoline then the problem is that your carb is dirty or the float is sticking and flooding the engine with gas. If the oil is at the correct level then the problem is more likely the valve stem seals, as the engine warms they leak. I presume you have checked the airfilter is clean? The choke is comming off completely when you move the throttle cable? The LT 1000 is the entry level rider in the sears line. The engine usually starts wearing out in about 50 hours use. Remember the sweetness of low price is long forgotten with the bitterness of low quality!

Many times a dirty air filter will cause this on this style of engine. When the filter is plugged, it creates a 'rich' fuel condition, and the engine smokes heavily, the excess carbon is drawn into the air filter, and plugs it even more.

check spark plugs, air filter, fuel filter, choke linkages (for full choke/no choke operation) and crankcase oil.

Crankcase oil can become fuel contaminated, thus overfilling the crankcase and filling the crankcase breather with raw oil/fuel, and this is drawn into the air filter, plugging it, and starting this senerio.

If there is fuel in the crankcase oil, drain completely, and refill with fresh oil. Then you need to look towards the carb for an inlet needle sticking, broken, worn.

Carb blows black smoke and runs bad but run good with no air filter or with a new filter


The old filter must be clogged. So if it runs ok with a new filter do you still have a problem?

17.5 h.p. b/s craftsman tractor oil pushes into carb. smokes bad!


Make sure it's not overfilled with oil.
if this is not the case, then you have excessive blowby, which is what blows past your rings when the air/fuel mixture ignites. there is only one explanation for this, faulty rings, and that's what it sounds like to me. the blowby forces the oil into the vent leading to the filter, and back into the cylinder, where it burns, creating blue smoke.
