Question about Tecumseh Horizontal Tiller Engine 8 Hp, 1" X 2 57/64" Shaft, Modelno. Hm80 - 155656x

I don't know what oil type to use for a Tecumseh 8.0 hp engine

I recently bought a Troy-bilt snow thrower model 42010 and I want to change the oil since it has not been used for several years. I do not have the engine manual and don't know the required engine oil type. Also, is the gas that has been sitting in the gas tank still ok or do I need to drain it and if so how do I do that?

Thanks, John

    I'm trying to help my neighbor change the oil on his Ariens 520 snow blower with a Tecumseh Snow King engine. He can't find his manual, so I need to know what type of oil to use, and where the drain plug is located.

Someone brought me a Toro CCR 2450 Snow Thrower. This appears to be leaking oil from the muffler. My gut tells me bad mixture- too heavy on the oil- but I'm not an expert and can't say for sure....

Yes, your gut may be right on the fuel mixture. It may also be the piston rings are worn and need replaced. But you should definitely try the right fuel mixture first! Another way to back up the gut is to take the muffler off and look into the cylinder that way. If there is a lot of carbon build up in there, then you know that that is the problem. There will also be carbon build up in the muffler too.

Good Luck!

My 18" Poulan is awsome,

When it overheats it may not be getting enoiugh oil. The oiler may be weak have it checked. I too, have a Poulan 18" Chainsaw and I think it is great. Everything I own is Poulan Pro or Troy Bilt. They are simply the best for the price.

I have a tecumseh 7 horse (Snow King) motor that has a blown head gasket. Model number is HSK 70. Where do I find a part number to order replacement gasket?

That does not sound like a complete Tecumseh model number.
You have several options... Your first and probably best option would be your local small engine repair shop. They may even have the parts in stock, if not in stock will likely have it in a few days. Or you can look online at places like outdoordistributors.
No matter where you get the part from you will need a complete model and spec and maybe a serial number ( off of the motor itself). Also be aware that since Tecumseh went out of business a few years ago that certain parts are becoming increasingly hard to find.

Many times moisture attacks the hexagon shaft that the friction disc assembly slides on. It slides from side to side on the shaft to create Reverse 1 & 2, and the other end creates 1-6 forward. With a wire brush and sandpaper, clean the rust from the hexagon shaft, at the same time lubricate the friction disc bearing with penetrating oil and with a soft hammer, tap gently until the assembly starts to slide on the hexagon shaft. After all the rust is removed and disc assembly is sliding, apply a light film of graphite grease on the shaft. You may want to re-lubricate on a yearly basis.

Tecumseh 8 hp problems

I had exactly the same problem, I tried to clean the carb several times without any luck. I gave up on the carb as it was an EPA style without adjustable mixture needles. Bought a new carb for it, installed it and the engine fired up right away. Took me 10min to let it warm up and dial the mixture, it has been fine ever since.

I recommend to buy the replecement carb old-new stock mfg pn: 632334A Tecumseh Carburetor with mixture needles

This place helped me out with one.
