Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

Hi. My name is Krzysztof and I'm from Poland (Europe). I just got Ariens snow blower from my friend and after 2 hours of snow blowing machine stopped working. It was strange to me that muffler is red after few minutes and engine was not perfectly running but my friend said its normal. It was also weak for me, it went down every time I drove into 8inch of snow (not ice mountain ;) ). Today i checked spark plug, it was dirty but after cleaning it produces strong sparks. I turn round crankshaft couple of times and piston was not moving (i thing it should), i saw only one valve going up and down, i was unable to see other one cause spark plug hole is too small. When I try to start gas is going out from carburetor ( there is no air filter ?!?!?!) Please help me to identify Ariens model cause rear sticker is damaged.

Here's what I was able to read:
-engine Tecumseh
model # H70-130210D
ser 8305C
-front sticker
model# 7-10-m
serial# 26156
-rear sticker
model# 10M ?????
serial# 15192

Sorry for my poor english and thanks for any help.

Probably I have Ariens 10M-L60D but I'm not sure.

From thing You wrote me I have gas and spark for sure but compression is out I believe. When I torn crankshaft and put finger on plug hole I havent felt any pressure.
I will check that again and probably I will take out cylinder head to see what is wrong. I'm afraid connecting rod is broken.

ps. what kind of gas should I use ? We got here regular 95, premium 98 and power 100+. 

Yep, definately a 1963 10M-L60D.
that year and model has a few distinct features that were unique to it..
easy to identify! :)

you can read more about it here:

I can also tell your machine does not have the original engine..
you have a newer replacement engine..
the engine serial number, 8305, indentifies it as a 1968 engine..

I identified my model from this great website bur I was not sure :) Its really magnificent that machine from 60s is doing so well - things were better these days. I got German machine in my bakery from 1956 and its only one that never broken and we are using it every day. Now I have to check everything and probably I will need new piston and rod.

Hi again folks.

As I thought there was no compression. But piston is running ok but there is very little loose on piston rings . Problem is valve on carb side, its always up. I can push him down, turn around but when it goes up stays that way. Valve on muffler side is going up and down, and I cant turn him around like other one. I took out cylinder head and drain out oil (it was really black). I was unable to take out cylinder cover cause screws are not metric and have to get right key.

Some photos form todays work:

Looks to me like you have a bad/broken valve spring or retainer. There's a lobe that pushes it up and the spring should pull it back down. Not a good thing but a lot easier & cheaper to take care of than a connecting rod so it could have been a lot worse. I can't figure out if a weak or bad intake valve spring could have caused you to run lean, I can see how it could cause a rich condition but not lean ... anyone care to guess? Your dirty Polish workbench looks just like my dirty American workbench :D

           If the engine was running before it quit..  You may just have a dirty intake valve stem..  If the engine has old or bad gas inside.  The valve collects deposits on the stem when running and starts to stick or rub...  if You spray cleaning solvent or carburator cleaner on the valve stem does it loosen up and move freely when you turn the engine over?

Can you Email me a Video of how the valve is acting when you turn over the engine?

Sorry I get Your post too late :( Gas can't be weak, It's from Shell and it's fresh 100+ octan V-Power.

Cover is out now.  Valve spring is broken, also governor wheel is completly broken. I will put some photos later, have to work now ;)
I promise to clean workbench after work ! :))

I have downloaded Tecumseh Repair Manual for my engine - it's great !

Have good day You all and Thank You for helping me. This is first time I'm repairing gas engine.

Ok I got almost everything done. Problem was broken valve cap.

Plase someone tell me:
- carb and those screws looking good ?
- I cleaned cylinder before photo, is it good or should I change piston rings ?
- should I poler valve holes ?
- can this valve stay ?

 

 My friend,  I would put it back together with the only the replacement parts for what is broke...   I think the valve spring keeper and parts are available separate.  The engine may have plenty of power in its current state,  even a engine that burns oil will run for years if taken care of...

IF you decide to change the valve,  you will have to resurface the face, cut the seat of the valve and set the clearance,   this will take tools you may not have access to do.. 

The needle valve screws look good, but you need to change the o-ring on the one with the seal...

Good luck,

Friiy    

the needles could use a good bath in carb cleaner and the brass seat(high speed jet) pictured in the middle with the gasket make sure the holes on the inside are absolutely clean.there should be a couple of small passages.  a small fine stainless wire and  cleaner will do the trick.
