Re: My tractor won't start
1) A machine shop rebuilt the block for me, new piston, turned crank and replaced one of the valves and grinded the other. They are a high-volume shop and I've had work done there before (I trust them). After getting the engine back I did nothing except put the lifters, cam & crank and bolt it all together (after making sure to line up the marks mentioned ealier).
2) I installed a new plug before trying to start it.
It ran fine before the rebuild, except for a loud knocking noise (which the machine shop guys said was the lower rod bearing).
I won't have time to work on it again for a few days because of school & work. I have the battery on a charger now but will try jump starting next.
