16hp K series
 
Hi guys, picked up a non running 16 hp out of a 1650 yesterday. Started tearing in to it today and found a bent exhaust valve, any recommendations on good replacement valves? Also the carb is in very poor shape and I don't think I'll be able to save it, are there any decent replacements that don't cost a arm and a leg? Thanks in advance !

How did the valve get bent?

How do you know? That's a picture of the piston......

OP:

Only way I can see that the screw could have bent the valve is if it got caught between the head of the valve and cylinder head when the valve opened. What kind of shape is the head in?

I think you need more than just a valve. Seriously......

Buy the valve from this guy on ebay:

There are lots of cheap carbs on ebay. Several members here have been buying them with good results. I have not bought any of them yet. I have lots of motors, and I just rebuild the carbs I have.

The head is ok, has one impression of the threaded portion of the screw. Nothing seems to be seriously damaged other than the valve. I've bought a Chinese carb
For a 10hp but it leaked gas out of every orifice lol, might have just been bad luck
