Default Purpose of angled motor mount

Ok, I've been trying to figure out why I see these angled motor mounts offered. I am building a suspension kart (Arachnid) with a larger than specified engine (GX390 clone). What I want to know is why does one angle the engine? to get it level was my initial thought. Searches indicate reasons like getting the carb to clear the rear tire, etc. This is not an issue with me, the kart uses a 45" rear axle, so I have plenty of space between the rubber. The rear suspension already slopes down by about 10 degrees. Won't know exactly until I get the rolling chasis completed. Is the goal to get the engine back to level under normal loading? This would be my original thought after blowing up so many 4 cycle lawn mowers as a kid on sloped lawns until i finally wised up and got a Lawnboy. Would like to hear from others what is the best situation to mount this engine?

I would think it's for better aerodynamics and lower centre of gravity, but not sure.

I'd just mount it level.

if your rear swing arm has that much slope make a 10 or 15* motormount to get it level or past level..

Kart racers use it so Carbs/airfilters and what not dont hit the rear tire... there motors are right infront of the right rear

Most of the time its just for clearence issues with the right rear tire and intake manifold and filters like freak said, You can also run less oil with a angled mount.
