yard cruiser smokes sometimes

[yellowbeard]

snapper Z rider, yard cruiser. 14.5 hp B&S. It runs great but it has got where it smokes on and off. lite blue smoke. Can be running along and it will start smoking for a couple of mins. then stop smoking then it does it again. thanks Joe.

Give us the model number of the engine so we know what you have. But the problem is sounding like then beginning of a blowing head gasket.

That is the EPA family number and doesn't mean anything to anybody other then them, and I am not even sure about that. the numbers I need will either be on the valve cover if OHV or on the blower housing if flat head. will say Model, type, code above the numbers.

Not to ask a dumb question but your oil level isn't over filled is it?

 

[yellowbeard]

hard to read model no. but I think it's 297707 model. 1236-f-1 type.

If the head gasket is starting to blow between the cylinder wall and the push rod cavity it will cause smoking sometimes intermittent. Also can be caused by pooling of oil in the breather The breather problem is not as common as the head gasket, so would start there.

thanks for the info. will start there.

Got it apart, It is the head gasket. Between the cylinder wall and the push rod cavity. But I dropped one of my valve caps, And I guess it went where all those socks go when they disappear in the dryer. Got to pick one up. Guys do you know the torque on the head bolts? and the steel push rod on top, right? thanks Joe
