Push rod replacement

my craftsman lt 1000 starts, runs and and shuts down after about 5 seconds. Just replaced alluminum push rod as the old one was bent..not sure if i am adjusting valves wrong or what else it could be.

Does it run fine those 5 seconds? Or does it surge, and when it dies, is it like you turned the key off or like it runs out of gas?

Kind of sounds like fuel delivery to the carb bowl is very slow.

So now it runs at full speed, but won't idle, opposite of before you cleaned the carb? If so, still carb problems.

It's possible they could be wrong, but since things are changing as you work on the carburetor, it sounds like carburetion issues. The carb can look clean but there are tiny passages that can be clogged in the casting of the carburetor. Double check the valve clearances... they should have about .005" at the most in the loosest possible position.

Take a flashlight and shine down where the push rod goes into the engine and make sure it is seated in the lifter. If so, and it still doesn't move, you may have a bad camshaft.
