Hi, Jim your instrument gauges and lights can alert you to most electrical and engine issues they can not warn you about failed engine gaskets or seals so your engine has to resort to old fashion alert methods of colored "SMOKE SIGNALS" here is a breakdown of their meaning:
1. COLORLESS OR SLIGHTLY BLUE SMOKE on start-up means your air/fuel mixture is the right composition and everything is well burnt in your combustion chamber.
2. BLUE SMOKE on startup is usually caused by failed valve seals dripping oil into the combustion chamber when the engine is not running.
3. YELLOW OR BROWNISH SMOKE at start-up means your air/fuel mixture is too lean. Too lean means that there is low fuel but high air mixture in your combustion chamber.
4. WHITE SMOKE on startup may be caused by a blown head gasket allowing coolant to enter the combustion chamber and may start dripping out of the exhaust pipes or mufflers. Smoke while riding is usually caused by worn out or damaged valves, seals, guides, pistons, rings, or cylinder walls.
5. BLACK SMOKE on startup is usually caused by too much fuel in the combustion chamber this can be due to air/fuel mixture adjustment too rich, accelerator pump improperly adjusted, faulty choke or not in the off position, air filter dirty and clogged, faulty carburetor float needle and seat, pilot jet too large, fuel injectors leaking, smoke while riding is usually caused by the main jet being too large or a damaged carburetor.
It should be noted that aggressive or abnormal throttle operation will cause these conditions to manifest themselves exponentially.

Could have a bad map sensor. The Map sensor is located on the throttle body. I have seen countless Jepp that start blowing black smoke when they go bad. That would be a good starting place.

SOURCE: LT 1000 flooding gas out muffler and stalls, then pours in carb.

Check your oil. Does it smell like gas? If so, don't run it even if you could. You will fry your engine. The float needle and seat in the carb are leaking. In other words, the float needle is not shutting off the gas when the bowl is full. You need to have them replaced.

SOURCE: golf cart smoking

It is most likely related to the rings, but running it would unstick them very fast if they were stuck. It's possible that sitting let rust develop in the cylinder walls and there may be some grooves in them now. They could also just be really worn cylinders. They make some oil conditioners which I wouldn't recommend on a car, but might work fine on a golf cart. I can't recall the name, but it was in a silver can, maybe called engine restore... You could always try that before resorting to a rebuild.

If it's running rich already, a bigger jet will just make it run even richer.

As far as the rear cylinder running hotter, that's just the nature of the beast with a V-Twin engine, because the front cylinder blocks the airflow to the rear.

Move the clip on the jet needle lower on the needle. This will help with the flat spot by giving fuel earlier. The black smoke is a rich fuel mixture. Check to see that the carb kit had stock jet sizes. Be sure to synchronize the carb slides so they both begin to lift at the same exact moment. tombones49_223.gif

Thanks for choosing FixYa and welcome. Since you are seeing smoke, it is usually a sign for rich gas and air mix. This could be caused by a choke that is slightly closed, a defective carburetor, or the carb may just need adjusted. You need to make sure the choke is completely open though. I would suggest cleaning the carb and adjusting it if necessary. Refer to your manual for the correct procedure. Check around your cylinder, head, and the shroud of the mower. Make sure the cylinder has nothing on it to cause smoking. See if cleaning the carb helps the performance. You may need to change the plug wires, if you didn't the first time. You could have a bad plug wire. Sometimes you get bad plugs but it is very rare to do so.

Black smoke indicates a too rich fuel mixture. Be sure the air cleaner is clean. Install a new spark plug. Check what size the main jet is. The prior owner may have installed a larger than stock main jet. There will be a number stamped on the side of the jet. Call the dealer and ask what the stock jet number is for your bike and then tell them what you have. Go back to stock.

Why does my 81 toyota pickup smokes black smoke


Your running real rich. most likely the float in the carb is leaking or stuck or the needle valve has crude on it that can be cleaned if you take the carb apart.

Motorcycle cuts out and backfires when accelerating. black smoke puffs out when backfiring


I need more information. Is the bike carburated or fuel injected? Did it just start this or has it been doing this for a while? It sounds like either an ignition or a fuel problem.

If it has a carb, I'd say that it's jetted way too rich or the main jet has come loose in the carb maybe. Tell me what kind of carb is on the bike if it is indeed carburated. I need the year model of the bike and the name of the carb on it. Maybe I can tell you how it's supposed to be jetted. If the main jet has come loose, you will lose control of the amount of fuel going into the engine at wide open throttle.

You may have a bad spark plug as well, either get a new set or have the ones you're running now cleaned. When you pull them out, look and see if they're really black and sooty looking. This is indicating a rich mixture. Check your spark plug wires and make sure they're in the coil correctly. Check of loose connections at the coil primary (small wire connections) connectors. Make sure that chrome cover over the coil is not loose shorting out the ignition.

Fuel injected, I can't help you with that as it takes a special device to make any adjustment in that system.

Only runs half throttle


so, can you tell me what kind of carb was on the bike before? was it factory? and what kind of carb was just installed? blue smoke can be caused by burning transmission oil or a rich fuel mixture. that might be a bad crank seal or case gasket, or just improper fuel/oil ratio or improper jetting. black smoke on the other hand is usually caused by too much gasoline burning, but if there were enough gas entering the engine to cause black smoke, the bike probably wouldnt run at all. but, if you can give me more info on the carb swap, and if possible any jetting information or jetting changes, thenI can definitely tell you what your problem is.

Smoking horribly


The white smoke indicates the need for new valve guide seals. The black smoke indicates that the fuel/air mix is far too rich. Re-jet the carb to stock #137 main jet. Don't mess with the pilot jet if the bike idles okay. No other settings to mess with. Install a new stock plug ; NGK R CR9E

ALWAYS have a fire extinguisher on hand when working on carburetors.
Drain the carburetor. There should be a screw on the lower side of the carb float bowl. Remove the screw then replace it after the fuel drains. Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Check the jet needle clip on the top of the needle. Put it in mid-range. Put the carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine.

I just thought of somthing. You may be creating the rich mix problem yourself. See the following starting instructions.

There is a proper way to start the engine. Four controls are on your bike to assist in starting.
  • The choke, used when the engine is cold. Pull the red knob for choke.
  • The " Hot Start " Lever, used when the engine is hot. Pull the lever to lean the fuel mix when the engine has been running.
  • The de-compression lever, always used.
  • The throttle, used to prime the cylinder.
Don't kick, instead, push the kick lever downward. You will feel the back pressure as the piston is going upward on the compression stroke to the point the pressure is great enough that the kick lever "locks up". You are very close to TDC. NOW, pull in the de-compression lever. Push the kick lever a little bit more to get the piston past TDC. Now release the de-compression lever. Give the throttle a 1/4 turn then let it snap closed. A diaphragm in the carb gives a shot of gas when this is done. DO NOT do this multiple times because you will flood the engine. Leave the throttle closed when kicking. Now give a strong kick through the full sweep of the kick start lever. Quickly get your foot off the kick lever at the end of the kick to avoid any chance of "kickback" from the kick lever. This happens in the case of a misfire, aka > backfire. It can be very painful, and can even break a leg. I am serious about that. Repeat the process (but without the throttle priming), until the bike starts. A good battery, a clean spark plug, a clean carb and clean air filter will also aid in starting.

A “very helpful” rating for this answer? Thanks!
