Animal angle mount or flat mount?

[Charles Pou]

I just got an Animal to race box stock in the MARRS laydown class (roadracing).

The guy I bought it from tells me to get a 15 degree angle mount, so I did. Now one of the guys I will be racing against says get a flat mount. On second thought, I think a flat mount is probably better for my application, i.e. lower on the kart, better aero, provided I have clearance over the rear tire, etc.

The angle mount I now have puts the engine pretty high on the frame. It's a conventional 2 piece leg mount. Why do they make mounts to place the engine so high? If it's to raise the center of gravity for dirt oval racing, that's not needed for my application.

Also, I noticed the Walbro carb is not level. Being a float carb, appears it should be level. I know about the adjustment I can make where the carb bolts to the manifold. However, it's not going to be enough to level it on a 15 degree mount. Besides, appears if you twist the carb on the mainfold it will restrict airflow.

Is a 15 degree mount going to cause my Animal carb problems? Maybe 15 degree mounts are for modified Briggs engines running a pumper carb (Tillotson) on a dirt oval track.

Nothing wrong with dirt racing, I have been running a 100cc piston port at Kam KartWay for a few months now and it's a BLAST!

Any comments welcome.

You're probably right as for the aero of it being at 15 degree's, but you can make the carb work just fine there. I would recommend a 5 degree and you will have no problems with tire clearance, oil sump action or carb float bowl angle. Also if you run an adjustable mount with a plate that bolts to the complete bottom of the motor, it will save the case from flexing like the 2 leg mount you have now. Burris makes mounts that fit either frame rail spacing that are very rigid and adjustable.

Hope this helps

Just about every enduro kart I know of is running a flat mount. No problem with oiling or the carb on flat mount. I like 16 ounces of oil for the flat mounts.

Thanks for the replies.

I mounted the engine on my Coyote Bullet today with the mount I have. It was pretty obvious I don't need a 15 degree mount for clearance.

Buller makes a nice adapter plate that I will probably order and use with a flat chassis plate. Thanks
