I have a Centura 3.5 Tecumseh lawn mower. It sat

I have a Centura 3.5 Tecumseh lawn mower. It sat unused for a couple of years. Today, I filled it with gas (the tank had been completely emptied last time it was used) and it finally started up. After mowing for about 15 minutes, the engine quit. And white smoke began emitting from it. :( You could hear a bubbling/boiling noise coming from it and I decided it was best to leave it cool down. Any ideas? Was the gas "boiling"? Why would this happen? What do I need to do? Please help, thank you!

    I don't know how to check the oil. Sorry for sounding like an idiot but I had a riding lawnmower for a few years...prior to that, I had a husband who took care of the push mower. I've gotten rid of both. :) The only other removable part is the lid for the air filter. There is nothing on the inside of the lid that says "oil goes in compartment to the left of the filter" so I am clueless. I tried internet searching for some type of manual that might assist me, but came up with nothing.

If the oil level is too high smell the oil to see if it has gas in it. If it does the carb needs to be cleaned and the oil changed.

This could be 3 of possible solutions to this problem..
From a Sears Tech of 22 years,,,,,,,,,,,,,,

1) Replace the Fuel Cap! Remember that air must fill the void of the fuel going out to the carburetor, If the fuel cap is clogged It will cause poor performance.

2) Clogged fuel filter or bad fuel line, Ethanol in today's fuels can cause many problems for fuel related components in any engine that is made today!

3) Carburetor and Ignition, including flywheel timing key! Possible sheered flywheel key, Lack of fuel to engine over 5 minutes. Vapor Lock? Change to different fuel filter!!!

What weight of oil should be used in the walk behind Ariens Mower


Most mowers today have either a 3.5 to 7 HP Briggs and Stratton or a Tecumseh engine on them and they usually recommend a straight 30 weight oil in them; not a multi-viscosity, since you do not run them year round. A good synthetic 30 weight is even better and will hold up longer between oil changes. I run 30 in all my mowers. Best of luck to you.

Toro recycler 20017 is very hard to start. it has to be primed many times. after it run a while it starts on one pull.


The carburetor may need to be serviced. You need to find a parts shop that handles Tecumseh parts. You will most likely need a rebuild kit for the carburetor. The carburetor part number is 640303. The rebuild kit is 632809. The Tecumseh engine company shut its' doors 3 years ago. Finding parts is becoming harder and harder. I've heard that someone has bought Tecumseh over the winter but it is unknown when the new parts will hit the market. Best of luck to you.

The needle and seat are bad in the carburetor. You need a tecumseh part 631021barterjoe_2.jpg and it might be recommended to get a service manual. They are inexpensive at a shop like www.arcolawn.com

I have a Sears Craftsman mower with Tecumseh, major oil leak


On many Tecumseh engines, there is a crankcase breather located under the flywheel. It has a cork gasket to seal the top plate of the breather. Either the rubber breather housing is cracked, or the cork gasket needs replaced.

SMALL ENGINE PROBLEM


Carb will need to removed and thouroughly cleaned.
Also you can file or clean coil where the contacts rub on flywheel.
Change your spark plug as well.
