SOURCE: carb trouble on harley Sportster

Not saying this will be your solution, but certainly worth considering. We had some Onan generators that sat too long at out RV dealership and were basically told carb would need replacing, as they do not have rebuild kits. At $500 a shot we decided to dump some Lucas fuel treatment and fresh gas in it. We basically tripled recommended dosage on bottle, and when engine ran we had enough lucas in there that it smoked like crazy but ran. We would run a little more through it, shut it down, let it sit for a few hours, start again, run a little, shut it down. Then let all that cleaner sit in overnight, and filled it with fresh gas again, and started it up, and after an hour or so of running steady, quit smokin, and ran like a charm. $10 worth of Lucas vs $500 carb. Did same to 3 other generators with same problem, and 2 out of 3 were cured. As it says on their site, too much will not damage the engine, so we didn't worry about that. After they were running good again, we replaced spark plugs and they were good to go, and owners were thrilled. Maybe we got lucky, but for $10-$15, I'd try it.

Backfiring out of the exhaust is usually an ignition problem. Unburned fuel is getting into the exhaust system because it's not being ignited in the cylinder. When the engine fires on that cylinder again, it ignites the raw fuel in the exhaust causing the pop that people call a backfire. I'd investigate the ignition system. Connect a timing light to each of the spark plug wires if it has a single fire ignition or either of them if the ignition system is the stock dual fire. Start the engine and watch the timing light to tell if the engine is missing as the light will miss a flash.

Good Luck

Check to see that there are no exhaust leaks as this is one of the main causes of back firing.

2005 sportster 1200 carburater not getting fuel

1. remove the full line from the carb, turn on the petcock and watch it flow into a container. Make sure that the petcock is in the correct position and that the tank has at least a half tank of gas. If the petcock does not flow gas, the tank/petcock has a fuel flow issue. If the petcock has a smaller rubber line connected (vacuum controlled) to it, it will need vacuum applied to it before it will flow fuel. Vacuum can be applied using a hand held vacuum tool (purchased at a auto store) or light suction from the mouth will do.

2. If the petcock does flow fuel, remove the inlet to the back of the carb and spray a 1-2 second burst of starter fluid into the carb and attempt to start it. If it attempts to start after spraying it with starter fluid, the carb is plugged and needs to be cleaned.

I left my Suzuki DR-Z 125L out throughout the winter and now its trying to start but it wont. I replaced the spark plug and put in new oil.

Clean the air filter then spray some starting fluid in the carb intake. The carb may be a bit gummed up from gas evaporating over the winter. If so, clean the carb with spray carb cleaner. Be sure the float starts and stops the flow of gas properly.

I spray some gas in the carboraitor.It runs for about 5 sec. and stops.There is gas in the tank.

Your Coleman power generator's carburettor is clogged. Your can tell that this is so, since
when you circumvented the carburettor (by spraying fuel), the engine worked.

Last time I fixed a clogged carb, I put it into a coffee can, hosed it down with carb cleaner spray (and some WD-40, which I had alot of at the time), and let it sit in cleaner fluid for 3 days.
It worked perfectly after that.
Failing the "soak it in cleaner" solution, the next step to getting your carb to work is to rebuild it, by purchasing a carburettor rebuild kit for your specific carburettor.

Next time, instead of spraying gas (this provides gasoline like a primer bulb would), you could also try spray "Starting Fluid" available at any car parts store - but gasoline works too. Anytime I debug a small engine, there's a can of spray starting fluid nearby.

Wont keep running

Remove air filter and clean carb with carb cleaner. spray start spray .
If that don't do it check the pickup tube filter inside the gas tank and see if it is clogged. Sometimes there is enough slack in the line you can snag it with a piece of wire. Spray it with the cleaned or if needed get a new one and replace it.

I would suggest 2 things to start.

1. Get a can of carb cleaner in the spray can and spray inside the carb.

2. Get some fuel line cleaner and put in the gas tank.

If neither of these fix problem, a carb cleaning is undoubtedly in order.

(If there is old gas in the tank, by all means drain and fill with fresh.)

Gas is streaming out of my overflow line.

I don't work on Harleys but I know it is a stuck float when the gas flows. The following is what I tell the Japanese bike owners.

This is a carb float being stuck open. Turn off the gas and drain the offending carb(s). Next, turn the gas back on and sharply tap the float bowl with the plastic handle of a screwdriver as the fuel bowl refills. The goal here is to vibrate the float to free it up. If doing this process a couple of times doesn’t free the float I would remove the offending carb(s) and clean with a spray carb cleaner. By the way, the float itself could be bad > filled with gas instead of air. Clean the air filter then re-mount carb(s).

Please rate this solution. Thanks!

Drain the carburetors. There should be a screw on the lower side of each carb float bowl. Remove the screw then replace it after the fuel drains. Is there any water in the gas? Remove the water trap bowl at the bottom of the petcock, (gas valve). Is there any water or trash in the bowl? Drain a cup of gas from the tank. Is there any water or trash in the cup? Dump it, clean it and re-mount it, (not all bikes have a water trap bowl). Turn the gas back on and wait a minute for the carbs to fill with gas. Install new stock NGK spark plugs and try to start the engine. If the bike doesn't start and run properly then shut off the gas and remove the carburetors from the engine.

FOR EACH CARB > 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. Remove the two screws on the outside throat of the carb and spray into the screw holes as well.
< < READ CLOSELY > >
Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two screws down. Only screw these in until they LIGHTLY seat. Now turn each screw one and one half turns outward. Put the rest of the carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. This process should get you back on the road.

Check the start stop switch, sometimes they can get dirty causing the saw not to get spark. Also maybe check Your air cleaner. if it's clogged it may be flooding itself out?
