Have just acquired a Kart with a non running Animal Eng. It has no compression. I am trying to put a plan together to repair/replace the engine and am looking for help to determine the best "next steps". Is there a shop manual for this engine, model #1243 32 8003 01? Where does this engine fit in compared to other engines. Thanks for your help.

If you talk the talk you should walk the walk
Take the air shield off the top of the cylinder and look fo this.

Also, how are you checking compression? Compression tester?
Some cams still have the compression release on them (yes, even ground cams for the animal class.)
Head gasket (as Jimbo pointed out) or valve/seat seal is likely cause of excess leakdown.
The rings in these things seem to last forever (at least the compression ring.)

I have problems with my exhaust seat dropping out and holding the exhaust valve open. Luckily I have a automotive machine shop that will install new seats for free. Lot cheaper than a $500 billet head

hey Brian thanks for the info. Checking compression by pulling the starter cord.....no resistance. I am not aware of a "pressure release" how would I check that?

If you use oil without a rust inhibitor you increase the likelihood of this happening.
When the springs rust and become pitted breakage is much more likely.

Yep. Good start.
You can get a longer rod, higher compression piston for it. 2.437" Stroker crank, open up the head, big valves, roller rockers, and a big stick to match. Then bolt on a big carb to let'r breathe and get ready to have some real fun.

You can build it to the hilt to begin with, or upgrade a little at a time as your competition level (and budget) dictates.

Lots of variations of small block, you need to be more descriptive of the rule set with which you are dealing. Also there are big differences between small block and unlimited. The use of billet blocks for instance.
