My cousin brought a MTD snow blower to me. He said he got it with no compression. The engine has the number 270-WJ. It looks like it has seen very little use. Oil looks almost new. I have never messed with a MTD engine. Not sure if there are any problems that are common to these? I was going to start with pulling the valve cover and see what the rockers look like. I did not find a parts listing for a 270-WJ a much more common engine was a 270-WU. It does not look like this engine has a compression release. I give it a pull and the engine just free spins. Anything to look for?
 
Free spin like you pull the rope and then it slowly starts to slow down to a stop. Indicates broken connecting rod.

Get us the model number of the snow blower and we maybe able to determine which engine it is.
 
OK, it had the same engine as the MTD... It is a Troy Built... Better info always helps.

I give it pull and I get a couple spins. Bad rod?? Not sure no clunking. A couple pictures follow. They have so many numbers on it. I thought he 270 WU was the engine #... Not simple like the old Briggs. Pictures follow...

Awesome Thanks!! I was just going to ask about the valve clearance. I pulled the plug to check the piston and it moved properly. I did a compression test and it was so low I could not read any.

I pulled the valve cover and the intake nut was hand loose on the rocker arm. ??? I spun the stud out of the head. It was VERY loose. I checked the exhaust rocker and the stud too was slightly loose. But threads in the head were fine. So was going to reinstall and check the clearance and see what happens.

Not sure if someone was in there before me?? Or if that is the problem.
