start by closing jets (clockwise). Then turn jets 1 full turn counterclockwise. this should get engine started. Then adjust jets left or right to fine tune,until engine starts running smoothly.

Check the fuel. Pour some fuel into a clear jar and let it set. See if it seperates due to water in the fuel. Very common problem.

SOURCE: need to know the size to use to gap the coil and

The gap will vary, depending on engine wear.
If you have a ' feeler gauge', it won't take you long before it runs beautifully.
That's it,

SOURCE: Tecumseh LV195EA Starts then dies.

If the engine is running at all then your sensors should be ok. It sounds to me like its starving for fuel? Once the engine runs out of prime then it starves. Does the fuel system have a shut off valve? How about an inline fuel filter? Either could be plugged. I think what you will need to do is remove the carb from the engine and check to see if its clean and if fuel from the tank is flowing easily to it. Once you have the carb off the engine, remove the bowl from the carb by removing the bottom bowl nut. Use a small can or an ash tray to hold the small pieces. Shake the float back and forth to see if there is anything in it. Some floats are plastic and some are tin. If there is any liquid inside the float there is your problem. Otherwise continue on with your diagnosis by using a bread bag wire, minus the outer covering, and a little jet spray to probe and clean the internal jets. Pay particular attention to the center main jet which will have a small perpendicular air bleed hole near the bottom and to the air vent hole that is on the face of the carb where the air cleaner mounts. Any tiny piece of chaff will cause these to plug. For reassembly, the inlet needle slides into the float, and they are held to the casting by a pin. You can push the pin out with a small screwdriver and then grab it with a pair of needle nose pliers to get access to the float. Finally, check the O ring for cracks that goes between the bowl and the casting. This is an easy job, just take your time. Lawnboys are one of the better machines.

Auger does not engage on Ariens Model 924121 sno- Thro

first check shear pins in the auger ( try to turn big auger by hand, engine off)
then if they are good then try to turn impeller by hand, engine off
youll need to turn it a few times before the larger ones turn, but thats what you want
if they dont turn then you have sheared the gear box gears
be sure belts are good tooo

8HP Tecumseh with no spark

Check the gap between the coil and the flywheel. You can fold a dollar bill over a few times (3 or 4 layers thick) , place it against the flywheel , **** the coil up to it , and then tighten down the coil. This will give you a good clearance between the coil and flywheel and promote good spark.

Essentially I am suggesting you use the folded dollar bill to set the coil to flywheel distance/gap.

If it still doesn't work, I am at a loss. Is this a multi cylinder engine ? If so , does it have points or electronic ignition ?

No spark on tecumseh 4 hp lawnmower engine


There is a shutdown wire, this wire is grounded somewhere along the route. Look at the coil for this wire; it shorts the coil to ground so no spark can get out to the plug.
Let us know if you want to know something else accept the suggestion.
Thanks for contacting

Bolens garden tractor will not start

At this age, the engine will have points under the flywheel. If the coil is OUTSIDE the flywheel, forget fixing it and just replace the coil with a later solid state unit, then cut the points wire.

If the coil is UNDER the flywheel with the points, you'll have to stick with them, but replace them AND the condenser. These parts (and replacement coils) are still available, but decide quickly - Tecumseh have gone, and when all these old parts are used up, that's it.
