How do you make a go kart engine run better, more power?
i have a 5hp Tecumseh go kart engine . it is straight stock . nothing added to it or anything. it doesnt sound like its opening up all the way
Wow this brings me back …mini-bikes and all.
Typically these small engines have governors on them so they don’t rev past a certain RPM. Typically they are "redlined" at about 3600 RPM. You get much higher than that you run the risk of throwing the rod and blowing the case …not pretty. I would make sure the throttle is adjusted so that when it is full open, the throttle is full open. If the carb has two mixture screws (which I doubt), one of them will be for low speed or idle and the other is for high rpm …one or both screws may need a little tweaking. If you just have one screw make sure it’s adjusted to give the best idle. There may also be a throttle limiter of some kind …like a screw or stop used to tone down the top speed of the cart by limiting how for the throttle will open.
Used to be guys would swap carbs, replacing the cheesy cheap tiny stock carb with a slightly larger more sophisticated one from a small motorcycle …of course that would require making a custom intake adapter. All kinds of porting of the intake and exhaust, putting a thinner head gasket to tweak the compression ratio. But back then there was an entire aftermarket for this sorta stuff. These days there’s just no market for it so unless your handy in the shop you’re pretty much stuck with the stock setup.

The Elusive Go Kart Engine – Smoking, Choking and Backfiring – What is That All About?
One of the most valuable lessons to be learned when playing with go karts is engine repair. Also, like any big problem to solve, some of the engine problems can be very elusive and frustrating. I had this engine that just would not run right. It would run, but not fast, and it was very frustrating.
What would occur is that the engine would start and run just fine, but when the throttle was opened up the engine would just back fire through the carburetor, out the exhaust, blow black smoke and just would not get past really anything but idle. You can imagine my frustration. I have this elaborate strait tube intake (which really is a high rise manifold) and this oversize carburetor mounted to this 4 horsepower Briggs.
I had that engine torn down probably twice. Removed the head, checked the valve clearances, tore apart the carburetor, added more sealant to the intake runner and the carburetor interface…all to NO avail. The engine still ran like junk. Having just exhausted all remedies, I took off the engine and tore it apart completely looking for the elusive problem.
And after I tore it apart I had to laugh, and be educated. The points on the engine had a spring that keeps the points coming back into position. Trouble was, the spring was on sloppy, and allowed the points to literally float as the rpms increased. So what occurred was the engine was literally losing spark at the higher rpms. The floating points acted like a governor. Old “his and pop” engines actually use this method for slowing their engines down. Instead of playing with the throttle, they play with the ignition to slow the engine down.
Once the engine was reassembled the engine ran full throttle no problem. Understanding the reasons why engines behave the way they do is very important in diagnosing the problem. One of the elusive things about this problem though is the assumption that the points are fine, that the spark is consistent. The trouble shooting motto is question everything and exhaust it at the least cost.

Find out What You Must Understand concerning Go Kart Engines
Open wheel racing is just about as thrilling as it gets. Watching skilled Indy Car drivers race around a 2 1/2 mile oval track speeds over 230 mph can be an adrenaline-pumping thrill. Open wheel racing has existed for decades and go kart racing is a modification of this open-wheel sport. And just because go karts utilize a shorter track at slower speeds doesn’t mean they are not as thrilling. Also, lots of drivers use karting as a stepping stone to more expensive, competitive, and speedier racing. This is where some of the most recognized racers started their career. As with everything else there’s a big distinction in the type of karts that may be driven. Speed is mostly determined by the size of the go kart engines, but it is also influenced by the quality of the go kart frame, particularly when it involves cornering. If you stick with it, you might in due course work your way up to the Super Karts that achieve speeds in excess of 160 mph. Or you can decide to race other varieties of go karts that will be slower. Recreational go karts found at neighborhood family fun centers will provide speeds that may reach merely 10 or 15 mph so there’s a big range for you to decide from.
4-stroke and 2-stroke engines are ordinarily used for racing. Completely different versions of the 4-stroke motor are extremely widespread in the amusement parks and fun centers, but electrical engines are growing in popularity. Electric motors have several benefits that make them good for short amusement center tracks. They’re terribly low-cost to maintain and operate, and only need a recharge when their juice gets run down. There is no need to fill their tanks with expensive fuel as they get their power from long-lasting batteries. And gas engines experience more mechanical troubles and therefore electrical motors are more affordable to maintain. Plus, since they don’t produce harmful emissions they can be operated indoors. The only negative facet to electrical go karts is that they need recharging after about 20 minutes of racing, but as battery technology advances these times are increasing.
Top makers of 4-stroke go kart engines are Tecumseh, Honda, and Briggs and Stratton. These companies build low-powered engines that will turn out somewhere between 5 and 20 hp. These engines are generally utilized by amateur racers or in family amusement centers. But do not let the little amount of horse power fool you; some of these engines can propel a go kart at speeds up to 50 mph. 50 mph may seem sluggish after going 70 mph in your automobile on the interstate, but after you get out on the track it is a whole new ballgame.
Several 4-stroke engines have extra muscle and will generate up to 50 hp. These engines can run at up to 11,000 rpm and are often used in varied National Championship class races, but if you wish to race at top speeds you will need to get a 2-stroke engine. Some 2-stroke engines will produce as little as 10 hp or fewer, but some can also turn out 90 hp or more at more than 16,000 rpm. Speeds in excess of 160 mph can be achieved with these sturdy 2-stroke engines.
In ancient days the engines were air-cooled, but with the faster speeds of today the majority of go kart engines are cooled with water. A number of the less powerful 4-stroke engines are still air-cooled, but the top hp engines are usually cooled by water. With the various differences in power, there’s an engine out there that is perfect for you, irrespective of what kind of racing you wish to do.

Where can I buy a rebuild kit for a 6.5hp go kart engine?
Where can I buy a rebuild kit for a 6.5hp go kart engine?
If its a snowblower style Briggs and Stratten, a lawnmower/small motor repair shop will have what you need. Those shops can be hard to find sometimes, but they are out there. Also rental places that rent machines with small motors can usually get them for you.

Does anyone know were i can get a performance cam for my go kart engine?
Its a subaru robin 6.5 169cc 4 stroke. And what carb can i add to make it go faster. What else can i do to make it go faster? The governer is removed already.
You could try some of the karting websights, but Robin is a spec engine in most cases, as in they dont let you mess with them in the kart racing world so no one makes HP parts for them, plus the fact Robin is there own design, now if you had the Honda Clone, which would be your Lifan, Jaingdong, or Ducar, or just a Honda, the list goes on and on for HP parts, you can buy a 6.5 from Harbor freight for around $150, cheaper if there on sale and have a 20% off coupon, get you down to around $90 bucks, then go here and get crazy,

How do I add a Key ignition to my go kart?
Ok, I want to add a ignition switch to my go kart engine that was not set up for one. How would I do this? The engine is a 6.5 hp GX200QX.
Its just as easy to pull a pull start and it run.
I don’t see that the QX model has a starter. If, in fact, your engine doesn’t have a starter, you are going to have to buy the appropriate parts to go along with that switch.
the parts can be bought from http://www.nr-racing.com/stockparts.htm
Scroll down a 3rd of the way, and you’ll see the parts for your Honda for sale ($279! ouch!)
There will be a panel that mounts to your engine that contains the stock start switch. You can either use that switch alone, or tap off of the two wires to a momentary, keyed single pole/single throw switch or to a single pole momentary push button.

Can You Replace A Electric go kart engine with a lawn mower engine?
I want to get a go kart. But real ones are expensive. So I was wondering if you could buy an electric go kart and replace the electric engine with a lawn mower engine.
You COULD,But the biggest problem your left with, is finding a gear box and clutch to go on it, so most likely you would have to do some pretty big modifications, so if your good with stuff like that, Go ahead, finding a gearbox and clutch to fit it is the worst, the rest is a piece of cake. The clutch is so your wheels don’t keep spinning and gear box is to change the shaft from spinning vertical to horizontal, you will probably need a something to weld with if you don’t already. Good luck if you attempt. JUST ADDING I SAW ON YOUR OTHER QUESTION JUST LIKE THIS, NOT ALL PRESSURE WASHERS HAVE HORIZONTAL SHAFTS, ONLY THE MORE EXPENSIVE ONES HAVE HORIZONTAL SHAFTS, HOPE THIS HELPS.

How could i make a 5hp go kart engine be more powerful?
i have a 5hp Tecumseh go kart engine . IT is just straight stock . I havent added anything to it or anything.
first off remove the governor, but being a Tecumseh I wouldn’t expect it to last very long, if it were a Briggs there’s tons of stuff you could do provided you have the cash. as they build engines just for racing go karts, Tecumseh builds engines for lawn mowers and such, and there not very good at doing that.
