Cat 3044c engine problems and the right stuff

As you may or may not know, I bought a new Cat 3044c engine last fall. I’m not the only one who had issues. They were so bad that the manufacturer took the decision to stop making them, and is offering owners to replace the entire carburettor with a new unit at a small price.

To me, it seemed that the original design of this carburettor is very bad. And if you know how a catalytic converter works, you’ll know that you have to take extra care with them.

I’ve had the opportunity to test-drive a new carburettor recently, and I can say that, contrary to all previous reports, I’ve found a pretty good alternative to the original model.

What follows is a quick review of my findings, from first impressions to some tests which were performed on a test bench and at home.

The original design

The 3044 is a single jet (carburettor) carburettor that is used in the first generation engines which came out in the 1960s, with engines like the 350ci and 360ci, and the 2 litre engine. This carburettor has been very controversial over the years, with many customers complning that it was producing excess fuel and was very hard to set up.

For me, it seemed that this was not only a problem in the design, but that it was one of the primary factors that caused problems in older engines.

I had to look a little bit deeper to understand how this carburettor worked. First of all, we have to understand how a catalytic converter works. It is a type of emission control device that absorbs harmful byproducts from the exhaust gases, such as carbon monoxide (CO) and unburnt hydrocarbons (HC).

A catalytic converter is composed of a metal catalyst that is placed in the exhaust of the engine. The catalyst does not work in the same way as the catalytic converters used in cars nowadays.

In a car, when the catalytic converter burns the carbon monoxide and unburnt hydrocarbons from the exhaust gases, it produces water and carbon dioxide. In this sense, it is an oxidizer, which causes the catalyst to produce heat.

The converter in a motorcycle, on the other hand, works in the opposite direction. This is a reducer, so the heat produced by the oxidizer, causes the catalyst to become colder and the catalyst absorbs carbon monoxide and unburnt hydrocarbons, reducing them to water and carbon dioxide.

This is why the original 3044 design had the problems we see in some engines. The 3044 does not produce the right amount of heat, so it was not able to produce a sufficient amount of water.

There are two mn factors that determine the amount of heat produced by the catalytic converter. One is the amount of r, and the second is the amount of fuel that is used to produce the engine’s power. If there is a low amount of r being used, there is not enough oxygen to burn the hydrocarbons, so it ends up absorbing the carbon monoxide instead.

There is also a problem of the design itself. The catalytic converter is designed in such a way that the catalyst is closer to the engine than in a car, which means that it can receive a lot of heat.

I have to admit that the design is a little bit odd in the case of a single jet carburettor. It is in between a carburettor and a conventional catalytic converter, and that’s a problem for an engine such as a motorcycle, where you want a compact design and low profile.

And I think it is a problem that they have not been fixed after so many years.

The new design

The new model 3044 has two mn differences:

1) The catalytic converter is moved from where the original one was, so it is farther away from the engine, making the design much more compact and low profile.

2) The fuel metering unit that was present on the original carburettor is gone, and the new one is not only more precise, but it is also a single jet, meaning that the needle valve is controlled by the r in the intake pipe.

I must also point out that, unlike the previous model, the new carburettor can operate with up to 100% throttle. The old one only supported up to 80%.

The other mn difference between the old and the new models is that the new design also has a smaller mn jet, so it will provide a more precise fuel flow for the engine.

In fact, I tested the new carburettor in my ’78 350ci, and I was able to make the engine run better than with the previous model. I was able to adjust the r/fuel ratio a bit more precisely, and I was able to reduce the amount of fuel used.

The test

I have already stated that the original 3044 had some problems, and that they have been fixed in the new model. If we look at the performance of the engine, the problems are still present in the new design. However, if you look at the old model in detl, you’ll notice some differences that are worth noting.

One is that, with the new design, it is possible to get the engine to run on a single jet, even with 100% throttle. The reason for that is that, with the new design, the needle valve is controlled by the r in the intake pipe. It is also possible to get the engine to run in carburetor or open r operation, and with the old design, this is not possible.

The second problem is the excess fuel produced with the new design. You can see this in my photos. It is difficult
