You can grind off the casting in the intake and polish it.also,you can upgrade your carb and exhaust.

A couple of possibilities. Look into getting head milled. That is, remove metal from surface area that contacts head gasket. A good automotive machine shop can help you out with this. Careful measurements MUST be made before milling and allow for valve/piston/spark plug clearances. There is a minimum allowable clearance for this procedure. If not careful, engine can be ruined with one pull of recoil starter if minimum clearances are not monitored.
You can also go to a thinner head gasket or no gasket. Again, an automotive machine shop can help you with the no gasket scenario. I prefer this method and have had varying results. It requires lapping to make perfect mating/sealing surfaces between head and cylinder block. Once this is accomplished, use a thin film of Loctite #515 Gasket Eliminator Flange Sealant and carefully torque head bolts to maximum spec. Power increase will be noticible and will probably have to run on premium gasoline to prevent ignition problems such as pinging. I have experienced the sealant blowing out which meant I had to go back to using a gasket.
I hope this gives you some ideas.

or you can simply make your own intake in turn you don't really have to spend anything on it and you can make it look pretty dam cool:D http://www.diygokarts.com/vb/images/smilies/biggrin.gif

just an intake wont show any noticeable hp. your best bet would be to do wat russ said or wat i would do is : billet flywheel, 94-ss Dyno cam, Arc billet rod, WRC(i think) stock size piston, wrc(i think) wrist pin, bigger carb, porting and polishing, and... o wait. this is for an 8 hp.... well the crap i said is for a Flathead. the things you can do is port polish, carb, un govern, and if you look hard maby a billet flywheel. try calling a kart racing shop near you. they will tell you all the parts that are made for your engine :D

jblankster: This is an L head (flat head) engine.

Removing governor will not give you more horsepower but will give you more rpm. Look at attachments. You should see a small linkage rod that connects governor to carburetor butterfly. Remove this rod and governor will be rendered useless. The point at where you disconnected the rod from carburetor butterfly is where you will now connect accelerator cable/linkage that runs to pedal.
Now, for my opinion.
Anyone who has to ask how to remove governor should not be doing it. This takes a small amount of mechanical "savyness" which comes naturally to a lot of us, but not all of us. I strongly suggest reading up on basics of internal combustion engines and get a service manual for your particular engine. It would help you tremendously to get a hold of a junk engine and just disassemble and reassemble it to get a feel for how and why things work the way they do. I see junk mowers that folks put in trash on almost a daily basis... especially in the Spring. My first gokart was made of wood and when I decided to add power to it, I located a junked reel mower that had a Briggs & Stratton model 5S circa 1956. Solid cast iron and really heavy for its size (I still have it). It was only .8 to 1.0 horsepower and could push kart about 18 mph. That experience stays with me to this day. It all started with an innocent question. I asked my father, "How do engines work?". That was 1962. I was about 10 or 11 years old.

You could get bigger carb and exhauset, no taking motor apart. You could also make your own custom exhause with some pipe and just bore out you carb you have now. Cheapest way i know of. I have a 8HP but had a carb that sucks upward and im new to those so im going to leave it alone.

Any bends are a restriction. Straight through intake and exhaust are most efficient. Efficiency equals horse power.
