I recently inherited a Craftsman 22" mower that has a blown head gasket. Pretty obvious, it's actually sticking out from where it's supposed to be. I have a friend in need of a better mower (and sad to say, this is much better). Thought I'd fix 'er up and put new front wheels on it (front wheel drive) and let him have it. I haven't a clue even what the make of the engine is. The model # off the engine is 143.996704 It's a 6.75 hp "Eager 1" I'd guess it to be 4 to 5 years old. I have a small engine shop that sells parts locally, but I thought I better at least have the engine make on hand. Also, what is the torque for the head bolts? And 2... It has no throttle, I guess I will see when it runs if it runs fast enough. I haven't really looked at it too close, but so far saw no adjustment for the engine speed either via cable or on the engine. wierd... Thanks for the help!
