Remove the air filter cover and the air filter so that you can see into your carb. Start the engine and allow it to warm up a bit. Keep your face a safe distance from the carb and rev the engine moderately. Watch to see if the slide moves up and down. If it does not move, you may have a hole in the vacuum diaphragm that controls the slide and it's not allowing your slide to be raised. If the slide is moving, your main jet is probably clogged. You'll have to remove the float bowl and the jet and clean it out. Check the slow speed jet as well. It's in a hole just to one side of the main jet holder. Also notice whether or not you see a squirt of fuel come out of the brass nozzle just inside of the mouth of the carb. If you do not see the fuel squirt into the carb when you open the throttle, you accellerator pump diaphragm may need to be replaced. It's located under a plate on the bottom of the float bowl.

Good Luck

My Toro Model 20070 that until now has always started on the first pull, won't start at all now. It started fine last week. It's getting spark (a little more yellow than blue). I replaced the plug,...

Hold the butterfly valve (behind air filter) open with a screwdriver, while somebody else tries to start it. Toro has had problems with atuomatic chokes. If it fires right up, thats the problem! If so, just wire it open, or contact Toro for a repair kit. Try using starting fluid, not carb cleaner, and spray directly into the head through the spark plug port. If you didn't do it already, blow out all the ports in the carb with compressed air, or carb cleaner. Also, be sure the safety lever is engaging correctly (top bar on handle) at the engine. Lawn mowers are pretty simple, so the problem is most likely simple too.

Hi Spinner3507, and the usual suspects are:
1. Idle speed improperly adjusted.
2. Intake manifold air leak.
3. Loose low speed jet.
4. Contaminated or plugged low speed system.
5. Enrichner valve not seated or leaking.
6. Leaking accelerator pump.
Good luck and have nice day.

I have a cub cadet weed trimmer. When i give it gas it will stall and quit

The carburator is plugged.
1st check your gas can and make sure the gas is not contaminated... no rust no dirt etc as it doesn't take much to plug those little carbs.
Go to a home center store and purchase a can of small carburator spray cleaner
Remove and disassemble the carb and soak the parts in CLEAN gas for about 15 minutes agitating every 5 minutes or so.
Using the spray nozzle blow out all the ports and then reassemble the carb.

2 other alternatives
1) Take it for service ( they'll probably replace the carb)
2) replace the carb yourself
You didn't include a model so I cannot provde part numbers

I sounds like your engine is running too lean. You didn't say whether your bike was equipped with a carburetor or fuel injected. If this is something that just started, you may have some trash in the carb partially blocking one of the jets, the slow speed jet. If your bike is fuel injected, I'm afraid that I can't help you there as I know nothing about the system. I'm an old school biker and work on the older bikes. I work on year models up to 2000 non-fuel injected. Sorry.

Good Luck

When pumping gas the pump constantly disengages as if the tank were full - it doesn't matter which station or pump. It goes off about 10 times while filling the tank. I've taken it to the dealer...

Back pressure is going into the gas pump handle. If you havent already done so, when filling your car play around with putting the gas pump handle tube in at a different angle. My car often gives me the shits doing this too. I find that if I turn the handle so that it is at right angles or even completely upside down with the tube pointing in a different direction within the fuel intake on my car it works fine. Can be frustrating though particularly on high flow pumps.

Yzf 250 carb settings not right.Bike is not running properly and has no power.keeps spluttering and cutting out. Can't get any idle adjustment

Drain the carb float bowl. Condensation from the gas tank has probably made its way into the bowl. If that doesn't help, remove the carb then remove the float bowl and use spray carb cleaner to clean the interior of the carb. Spray into every opening you can find.

Cannot put new hoses on the carb. I didn't take them off, and don't know what hose goes to the tank, primer, etcThank YOU KEN

Hi Ken,

If this is a chainsaw, you have fuel filter in the gas tank. Take the fuel filter with you when go to pick up new line. If it fits the filter, it will fit the rest.

Hope this helps. If it does, I'd appreciate a 4 thumbs up. Thanks,

So check the compression. The valves could be set wrong or are not sealing well. You didn't mention any smoking so the piston rings should be okay. The most likely cause of the problem is a pin hole in the carb diaphragm or a carb needing to be cleaned. Go ahead and drain the float bowl then remove it. Now clean the carb with spray carb cleaner. With a bit of luck the cleaning alone will fix the problem. Please rate my answer. Thanks.
