Tecumseh HSSK50-67336L

This engine is on a JD TRX24 snowblower with fairly low hours. It is very low on power. I don't have a compression tester, but it turns over way too easy compared to what I have seen with comparable engines. Given the age of the unit and general lack of parts availability for a 30 year old machine, I would like to do a fix on the cheap.
 
I'm thinking maybe new rings, a head gasket, and a carb kit.  However, I'm having some trouble finding what I need. I'm seeing ring options for a ...M model (same as "L" model?), and no clear options for a carb kit.
 
Can someone direct me to the right parts? Thanks.

    Unless it smokes badly while running don't worry about the rings. The head gasket or valves probably need attention though. Jack's has 31840 carb kit which is very reasonably priced.

    Thanks for the tip on the carb kit. I was thinking rings because after squirting some oil into the cylinder through the spark plug hole, there was noticeably more compression.

    Pop the head off and see if there is a ridge at the top of the cylinder indicating wear. Rings won't fix that, it would need a rebore. Look at the gasket and valves while you are at it.

    Following up here - I removed the head. Cylinder looks nice and clean with no ridge. There seemed to be excessive deposits around the exhaust valve. I will need to look at that in better light to see if there is damage or just crud.
     
    Can anyone point me to the right gasket kit to purchase here?
