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.

how long did you let it sit for with gas in the carbs, you may have clogged up your jets. after awile gas will break down and turn into varnish, if your bike trys to push the varnish through the system it will clog the jets. try to take off your seat then remove your plastic over the gas tank. remove the gas tank and you will see four bowls *silver ones right next to where the gas tank is on the carbs*. your bowls are in sets of two. there are drain screws on the bowls to remove the gas inside. remove the 16 screws holding the bowl onto the carb. *4 on each* inside you will see your floats and jets. carefully loosen the jets with a screw driver then finish unscrewing them by hand, they are brass and very soft. you should be able to hold up the jets to the light and see a small pin hole. if not get some carb cleaner and give them a squirt and blow them out. do not try to use anything to clean them out, they are very very sensitive and one knick will change the jet. after that i would spray some carb cleaner up the jet holes and try to clean them out also. if you have a compressor it would be wise to use that to blow out the gunk from the jet holes as well. after you run threw all 8 jets put them back together and see how it goes, if nothing you may have to check the jets again and if clogged again your carbs are gunked up and will need to be cleaned

if your getting no fuel at all to the carb then its the petcock valve it works off of vacume so take fuel line off and spin it over if fuel runs out then its fine that means your needle valve in carb maybe stuck. and in my case a stick pulled the vacume line off the intake that controls the petcock valve.

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.

Spark and gas??? Must have both. Pull spark plug wire and check for spark. If you have spark, check gap on spark plug. Check the bowl on carburetor. loosen bowl screw to see if gas is coming out. If you have gas coming out, carb needs to be taken off and cleaned or rebuilt.

My gas trimmer starts but wont stay running


hello sir, my machine will only start when pumping primmer bulb or squirting fluid in the carburetor than stops. the fuel line has broken off, in most small carburetors this is a ongoing problem.old fuel will crystallize when left in tank for a long time.plugging up ports, fuel lines, small screen in carburetor.fuel lines will dissolve clogging carb.this is why it will run when the choke is on creating a vacuum to where there is fuel forced in the carb to rum,also the gas will evaporate leaving the oil behind clogging up carb.the thing to do is remove carb. and clean out,replacing gaskets or fuel line if necessary.use carb cleaner to clean out carb.make sure to make note where fuel line go.the fuel filter broke off of fuel line letting debris get in carb plugging it up.the muffler is known to clog up a lot on these machines where they want run. the compression should be 60 to 120 lbs any thing below 60 is junk. when adjusting the carb screws turn in all the way than turnout 1 1/4 turns turn in slow until machine runs also you need to check for spark by removing plug and grounding against engine to check spark, ok.a new spark plug would be a good ideal too , if you are going to make these repairs use new fuel line and filter,hope this helps,any comments welcome,thank you, !!

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 can't start my honda lawnmower, checked the oil, put new gas use choke,it gives litle sound but not enough to start


Try a touch of starting fluid right into the carburator by taking the air filter off. If it then starts but wont run or stay running, the reservoir below the carb should be removed to clean at and the pinhole in the intake tube above the bowl nut. This is the most common problem with lawnmower start problems, the pinhole can be unplugged with one wire from a wire brush. Be careful with the gas, at least pinch off the gas hose with a vise grips while removing the carb bowl.. Never use a droplight around gasoline. most lawnmowers have no mixture adjustments, so it is a matter of cleaning the carb, tank, gas lines. Some oils in gas mix systems settle and clog after less than one season. Spark can be tested by sight, remove the plug and use a clip-on ground wire from spark plug body to metal on the engine with the plug wire connected.

Wont run without choke being pulled out 1/4 .


INFO:
-Remove Carb and clean, you have a high speed fuel port clogged.

NOTE:
This would also be a good time to replace your fuel lines, Take photos before you start.

RECOMENDATIONS:
-Drain all fuel from the Saws fuel tank.
-Remove and REPLACE with a NEW spark plug.
-Remove and RELPACE with a NEW Air filter.
-With spark plug and air filter removed and fuel drained pull the starting cord many times 12 or so to ensure there is no fuel in the chamber and also check for a spark at the plug.
-RE-MIX WITH NEW FUEL your 2 cycle oil to the correct ratio in a clean fuel can. it is OK to dump some in the Saws fuel tank slosh around and dump out in an approved container for disposal.
-Hold off on putting back on the air filter until you have had it running.

Hope this Tip Helps.
