Is this valve bent?

[bluefitness]

This is for a Toro pace lawn mower.

I wasn't getting any compression. The intake valve was stuck open. I freed it up and worked it back and forth. I noticed it looks like it is at an angle to the block. The odd thing is that if I rotate the valve, the higher side is always to the left. It is almost like the stem is at an angle and not bent. It lines up with the pin in the access hole. What are your thoughts?

On some engines the valves are not square with the block. Has to do with swirl patterns and other high tech stuff dealing with engine design.

I'm only getting 60 psi compression, and it is still not starting.
The exhaust valve is flush. Do you guys think I should try bending the intake side flush?

I would do a leak down test to see where the compression is leaking out.

Set the valve lash to 0.030" and see what compression you get
In operation the valve is supposed to rotate so bending is not going to be a good idea
The only engines where the valve is square on to the head are side valves

Unfortunately, I don't have a leak down tester. The intake valve protrudes on one side when seated due to it not being parallel to the head.

I've been trying to start it with a drill. Would that affect the compression at all?

What do you guys think I should try next? I'm close to just trashing the mower.

I don't think a battery drill will work, a heavy duty corded drill might.the recoil starter would work

OK. I'll try testing compression again with the pull rope.

Compression gauges are pretty much useless on most of these engines.

Double ditto on Fish's post
If the valve was bent there would be 0 compression and you would get gusts of air blasting back out of the carb
If the valve is bent it will appear to wobble when rotated
The valve has to be square on to the valve seat so it can seal , nothing else matters.
