Help!!!! Troy-Bilt

I don't see how there's a relationship between the mower deck and the problem you're having did the engine actually run okay before you messed around with the pulleys secondly it sounds like if you can't see the rocker arm moving then something happened to that push rod assuming I'm thinking of the right type of Engine. I think you're saying the valve on the bottom you can't see the rocker arm moving at all.

She's done.

I agree with Ilengine - the engine is done. I was just reading all your posts and replies...Looks like the valve spring broke, causing the valve to drop into the engine and through the piston. It looks like it scored the cylinder wall as well. If so, the repair will be a new engine unless you want to go through the hassle of honing the cylinder and inserting a sleeve. Since this is a fairly old post, I assume you've already replaced the engine?

Check the ground cable

For???

Oh I get it. It got sucked inside the engine. Case closed LOL.

Perhaps the valve keeper dropped off and allowed the valve to drop into the combustion chamber. On the next revolution - lunched the valve/piston/piston rod.

I just did this with a 17 hp Briggs. It cost a lot to repair but it is running fine now. Cheaper than a new machine, so I did the repairs.

Whats the easiest way to get this torque head screw off the connecting rod, i can get this cylinder head out??
This one is starting to strip on me.

Probably going have to try a hex bit driven in.

I did. I got one of them but the other one is stripping out.
I have worked on this one bolt forever.
Is there another way to get in there.
