Cylinoid could be bad which is quick fix. If not check magneto possibly need a new one or sometimes if it has rust on it you can take some sand paper to it...

clicks, wont crank ??? check ground first, then suspect a bad starter as long as the solenoid and battery are good... a 12v test light will help here

does it idle up and down at will,,,, and gets worse when hot? (if yes - the valves are too tight!!) maybe a little hard to start...??

The carb may need a professional cleaning!

Yes mongooses can be very aggressive toward cats.

absolutely, mongooses love to attack other animals.

Hi Matt only help I can give is look along top & bottom of chain for a tensioner it will be a round rubber wheel. If you cant find a tensioner it will more than likely you need to cut the chain down. If your not sure how to let me know & i'll let you know how. Also DO NOT USE IT while chain is loose as if you do & chain comes off you can crack engine case which then means a new engine

i have the same problem

make sure filter is clean not gunked up..try draining carb if there is a plug if not.Then try to clean the carb the jets could be clogged not hard at all to take apart.Good luck
