There is one other fine tuning variable that I’ve played around with. That variable is the float level. A person with even extensive knowledge of small engine carburetors would say that with the plastic float that these carburetors have that is not possible without some complicated measures. Actually it’s very simple. It’s done by tilting the carburetor on its round mounting spigot.

We will also cc the combustion chamber to be sure that the volume set at the minimum legal limit. After reassembly your precision built engine is tested on our Precision Engine Dyno. This service includes break in, jetting changes and adjustments to get maximum power from your engine. You get the printed read out with all the crucial settings documented for your reference. You will also get our special tuning and tip manual to help make your kart faster.

Quite often, when tuning a Comer C-50/51 with a restrictor, the tuner will find that even with the 58 jet, the biggest that stock class rules allows, seems to be too lean. Guess what, it probably is! This situation is not very likely at high elevations, but racers at lower elevations will run into this. I know I have, at lot, and I do most of my testing at an elevation around 1000 ft above sea level. One alternative is to reduce the amount of oil that is in the fuel mixture.

The float needle can form a ridge after a while (like a month) and stop working correctly. This is a good item to replace regularly. Finally, check the internal filter screen on the carb for debris. If you carb still doesn't work after all this it may be time to retire that carb for the weekend and send it off to an expert. Carb Cleaning - Cleaning Comer carb is a simple 10 minute task. Turn off your fuel shutoff valve. Remove your K&N Filter, loosen the carb retaining bolt, remove the two screws holding the black throttle cable/slider assembly to the top and remove the assembly.

Of course you will get more air into the engine with the stock filter housing with no foam at all but that will result in premature engine wear and possible severe damage. Since the aftermarket filters allow more air to flow it is logical that they require bigger jets, and that is true. Sometime 2 or 3 jet sizes will be needed when switching from a stock air filter to an aftermarket filter. By the way, the aftermarket fabric filters will pass plenty of air.

Those that don’t percolate at all are rare but are the ones that are desired. I have yet to figure out why this condition occurs even though I have thoroughly examined both “good” and “bad” carburetors and can’t visually find the difference. After making sure that your carburetor is in good shape and everything is functioning as it should the only thing left to do is make sure that it is fitted with the correct jet for your application. One thing is certain; there is no single jet size that will work best for every carburetor/engine combination. There are many factors that affect the correct jet size but they boil down to two factors; how efficient the engine is at pumping air and the density of that air. By air density I am referring to how much oxygen there is per cubic foot of air that is flowing into the engine.

Tuning it consists of changing the jets and that is about it. You'll read all sorts of internet lore about tilting it one way or another, or spacing it off the engine on the manifold a quarter inch or so, etc. Don't worry about any of this.

Air Density can be shown in a simple and easy measurement to understand called 'Density Altitude'. Density Altitude is the equivalent altitude you are in right now.

Starting an engine mounted on a kart on a stand with the wheels off of the ground is not even close to the best way to test the jet size. Too many new racers will run their karts on a stand and run them at full throttle while watching their tachometer to see what rpm it reaches.

This is especially true in the upper RPM range where the power just keeps on pulling. Works great on stock motors as well as full mod outlaw motors and is the perfect fix for those so called 'stock' motors that are continually running away from you. Great for adding that needed boost when visiting no rules tracks and then you can easily switch back to your stock carburetor for legal tracks.

The best way to tune is on a dynamometer. It’s a good idea to know what you are looking for. A well tuned engine will start relatively easy, will accelerate reasonably, and will achieve its top potential rpm on the longest straight away. Always start out the tuning session with a jet size that is presumed to be too big. The way to tell if it is too big is that once the engine is warmed up it will take off well with little or no hesitation but when it gets to half to ¾ of its maximum rpm it will start to “break-up” or miss from the ignitions inability to burn all of the fuel that is in the combustion chamber. The next step is to try the next smaller jet.

Just right= starts easily, accelerates well from a dead start, revs to full rpm without missing. The air filter makes a huge difference. The aftermarket fabric air filters, regardless of brand, flow a lot more air that the stock plastic filters with the foam element.

The engine should rev a little higher before it starts to break up. Now try the next one and so on. Do that until the engine reaches the highest rpm possible on the straight. You will know you have reached the limit when you try the next smaller jet and the top rpm either does not get higher or even results in a slight drop in top rpm from a too lean condition. You will probably have also noted that the kart did not start off as strong either and was probably a bit sluggish starting off. Go back to the next bigger jet and use either that one or the next bigger one. Also note, if two jet sizes both wind up with the same peak rpm, use the bigger of the two.

Trial reset 3.0 downloads. Now, how do you use them? Tuners like to monitor all sorts of environmental factors when evaluating which jet to use. Some by temp, some by humidity, some people just say 'the air feels heavy today'. This is all great but there is only one true measurement that takes everything into account and is a consistent means by which to tune. It is 'Air Density'. Air Density takes into account temperature, pressure, and humidity.

You'll want it bone dry come race day. It is a good idea to have several of them all with this treatment and switch them out over the course of a race weekend. This sums up carb treatment. The carb is one of the parts of your kart that should get the most attention between sessions. The tips above should keep you tuned up!

INSTANT BOLT ON HP! The is the ultimate hop part for your Comer 50. Our MM16 racing carburetor looks just like the stock carb from the outside but the bore is a whopping 2mm larger at 16mm. Dyno tests have shown increases of 1/4hp! This is especially true in the upper RPM range where the power just keeps on pulling. Works great on stock motors as well as full mod outlaw motors and is the perfect fix for those so called 'stock' motors that are continually running away from you. Great for adding that needed boost when visiting no rules tracks and then you can easily switch back to your stock carburetor for legal tracks.

You can throw away any jet you have that this Pin Gauge will poke through. Whatever is left are your legal jets. So order these size Pin Gauges from McMaster: •.0260' - This is your 'no go' jet •.60mm •.59mm •.58mm •.57mm •.56mm •.55mm •.54mm Now you can measure jets until you find jets that fit your pins from.54mm to.60mm, and these will be your jets. Throw the rest away or put duplicates down the other side of the PKT Jet Holder. The jets you now have in your PKT holder are all you'll ever need.

Sometimes a gas cap vent will lock up essentially locking your fuel supply system so the engine starves of fuel. Make sure your vent is working. The other common reason that makes a carb not work is a bad float needle. The float needle can form a ridge after a while (like a month) and stop working correctly. This is a good item to replace regularly. Finally, check the internal filter screen on the carb for debris. If you carb still doesn't work after all this it may be time to retire that carb for the weekend and send it off to an expert.

It’s a good idea to have a small weather station with a barometer so that you can predict what jet to use. It would be a good idea to keep a small note book in your tool box to keep track of this data and how the weather relates to your jetting. To summarize; Too Rich = starts up easily, takes off very strong, accelerates well but breaks up before reaching maximum rpm. This won’t hurt the engine but you won’t win either.

How the reader deals with that dilemma is his choice. Dellorto does make jets larger than 58 and Bergfelt Racing Enterprises, LLC does stock them. There is one other fine tuning variable that I’ve played around with.

Finally, you can remove the fuel inlet cap to expose the filter screen under it, and remove the filter screen. Now your carb is completely apart. Using brake cleaner (easier on plastic than carb cleaner) and air you can begin by blasting out every orifice in the carb with brake cleaner then blasting it clean with air, then doing the same to each part as you reassemble the carb. When you put the carb back on the manifold tighten the retaining bolt just enough so that the carb is very hard to twist on the manifold, but you still should be able to twist it. We see people every year breaking carbs from being overtightened.

You'll read all sorts of internet lore about tilting it one way or another, or spacing it off the engine on the manifold a quarter inch or so, etc. Don't worry about any of this. Here is what you do need to worry about. And I will cover all of these things in detail below: • Keep it clean, there is nothing worse than some debris in the carb affecting performance. It is a good idea to take it apart and clean it before every important session like qualifying, heat races and finals.

It should be dialed in. If these basics are covered and it is acting funny there are a few things to look for. One is your gas cap, is the vent working in it?

K&N Filter Cleaning - The K&N Filter needs to have as little restriction as possible. Don't oil it. Clean it out a few nights before you race with brake cleaner.

This sums up carb treatment. The carb is one of the parts of your kart that should get the most attention between sessions. The tips above should keep you tuned up!

C50carb.html Kid Kart Tech Tip Tuning the SHA Dellorto Carburetor Found on Comer C-50 and C-51 Engines No single tuning variable makes more difference in the performance of the Comer C-50 and C-51 engine than getting the carburetor tuned just right. Actually that’s true for tuning just about any engine but especially the tiny Comer engine, which has found its way onto kid karts the world over, since it has such a limited power potential to begin with. In one sense the carburetor has a relatively straight forward task to perform; to supply a properly measured mixture of fuel and air to the engine.
