Did you check the jets they probably clogged and they are flooding the chamber .

Testimonial: "Yes, I cleaned the carb thoroughly. took it out, parted it, cleaned it in boiled water, dried each and every part, jets with compressed air....may be i will check the spark plug wires, right? "

SOURCE: need to see the carburetor diagram for a 2000- wont start

I could not locate a diagram of your machine's carburetor. I can tell you, for certain, that the carb does have a rubber drain tube that goes from the bottom of the float bowl and vents to atmosphere beneath the vehicle.
There are three required ingredients required for combustion: fuel, compression, and a spark (at the right time). Try to find out which of these are missing. Loosen the drain screw on the float bowl. Is fuel present? Check the compression - you've got to see at least 140 psi for anything to happen. Pull the spark plug and crank the engine. Is there a spark?
If it has sat for an extended period of time (more than just a couple of months) then the carburetor will be plugged with fuel varnish. It is very easy to think you've got everything cleaned, when the jets are still plugged up. I would take the carb apart and remove the jets. Hold them up to a light source and look through each one. If you can't see through them, there's the problem.

finally sorted when I replaced both plugs. I've never come across one failing instantly before in 30 years of motorcycling (maybe that's because I ride old bm's!)

IF you have a battery get a new one ; put in new gas ; super; dsid you ajest any screws on carb. You tight need to run a prime tank right to your carb to prime it; and then hook your tank backup new gas lines to your carb. Now break out with the WD40 to spray all switches for rust.

You will have to clean the carburator, blow the jets with compressed air,check the float level too and reset.
Good luck.

Coleman Powermate starts but dies after 10 seconds

It sounds like you've already done a lot of troubleshooting, but here are a few more things to check:

Spark Plug: Check the spark plug for any visible damage or deposits, replace if needed. Make sure it is tightened properly and there is a strong spark when cranking the engine.
Fuel Filter: Check the fuel filter for any clogs or debris, replace if needed.
Air Filter: Check the air filter for any damage or clogs, replace if needed. A dirty air filter can restrict air flow to the engine and cause it to stall.
Vacuum Leaks: Check for any vacuum leaks in the fuel system, this can cause the engine to run poorly and stall.
Governor System: The governor system regulates the speed of the engine. If it's not functioning properly, the engine may stall. Check the governor arm, linkages, and springs for any damage or looseness.
Ignition System: Check the ignition system, including the ignition coil and ignition module, for any signs of damage or wear. Replace if necessary.
Fuel Pump: Check the fuel pump for proper operation, the fuel pump may be failing and not delivering enough fuel to the engine.

These are just a few possibilities, and it's best to consult the owner's manual or a professional mechanic to diagnose and repair the issue.

Stihl br350 backpack blower will only spark when pulled fast. It will not start pulled fast or slow!

To start a small two stroke engine the rope needs to pulled rapidly. So from what you are saying I believe that your problem may not be in the ignition system. An engine needs three things to start and run- air, fuel and spark. Make sure that it is getting enough air by checking the filter and make sure if its a foam element that no foam has torn from the element and been sucked into the engine. Clean or replace a dirty element. Check the fuel filter and make sure that fuel can flow freely through it. Even a tiny amount of dirt can clog a filter enough to hinder flow to the carburetor. Replace the filter if it's dirty or over a season old. Clean the carburetor THOROUGHLY! Use a good quality carb cleaning spray and make sure the diaphragm isn't hardened or creased. Replace any part that's questionable. A way to test start the engine is to put a few drops of pure gasoline in the spark plug hole and quickly replace the plug and pull the cord to start it. If it starts for a moment the ignition system is good. Don't do this more than a few times cause a two stroke engine requires oil in the fuel to lubricate the rotating assembly and running straight fuel for more than a few seconds can damage the engine. Do not use starting fluid it damages two stroke engines.

Hp gas

Follow gas line from tank to carb. Observe bottom of carb. Remove screw holding carb bowl to carb. Clean bowl. Pinch off gas line with pliers. Ensure float falls down easily. Float up no fuel flow, float down fuel flow. Observe screw that hold carb bowl to carb, see if it has a whole thru it, clean with small wire, bread wrapper works good. Observe center fuel port, clean with wire. Remove pin that holds float and meter needle, clean port with wire. Reassemble. Ensure air filter is clean, oil is full, 30w oil, spark plug is clean and properly gapped. Replace air filter and spark plug once a year. Empty old oil out if any grey is observed in oil, this is moisture, can accumulate after winter storage. Clean out side of carb with carb cleaner to ensure choke can rotate freely. Always use Stabile in gas.
All newer mowers have a low oil shutoff.

You may have to replace the carb.But before you do.Check the the fuel line.There is a small screen in the carb,it may be clogged.Inside the tank is a small cylindrical filter,make sure it is good.Break the fuel line at the in line filter,to make sure gas is getting to there,if it is the problem is in the carb.

Poulan 6.75 Lawn mower will not start

Remove spark plug, clean and dry. Replace plug. Remove air filter. Spray WD-40 into carb opening; one second blast. Turn over engine, (pull handle). Engine should start briefly and run for 3 seconds. If not, you are not getting spark to spark plug. If engine starts, you have a dirty carb and you can buy a rebuild kit from manufacture.

Has spark, fuel, turns over but will not start

3 things are needed for combustion (compression, fuel/air mixture & spark).

turn the key on. can you hear the fuel pump running to pump some fuel into the carbs? if no sound, then it might be a fuse or relay, or the fuel pump inself.

if you hear the pump clicking, then next try this. petcock on try and crank it. try for a few seconds (<10 sec) to give a start. stop cranking and immediately pull out a few of the plugs. are they wet? if they are, then fuel is making it to the cylinder(s). if dry, then no fuel to the carbs. check fuel filter & vent.

next turn to spark and see if that fixes it. don't look at the spark, but replace them. it has for me on dirt bikes and ATVs. one minute it was running, shut it down for a break and when trying to restart, nothing. changed out the spark plugs and she's back to life. never had good luck with NGK plugs.

worth looking at the air filter too. make sure you can still see light through it when holding it up to a light. and you should feel/hear a suction while trying to start it which means the passage to the carbs are clear.

take a look at the plugs themselves. is it black (like its running too rich?) or is it very white like a new plug (lean condition)? should look like light brown toast if its running right. throw in a few new plugs (properly gapped of course) if they look black and give it a try.

if nothing from above works, then go with lrandall's recommendation and check compression. you can rent one if you don't have one.

good luck.
