Small engine will not run without choke being on ?

Answer 1

Find the mixture screw on the carburetor..& turn it counter-clockwise a bit..Open the throttle & turn the screw in or out very slowly until the engine purrs. If this doesn't work..then the engine isn't getting enough gas..you may have to change a filter or blow out the gas line.

Answer 2

Small Engine Choke

Answer 3

Yes - it is starving for gas. Not sure what kind of small engine you have. Small engine's gas tanks have some type of filter, either in the tank or in the line / tube that feeds the carburetor. You could check this. If you have a carburetor that sits on the tank, pull the carburetor and you will see a screen on the plastic tube - check that screen and the little bowl area that the tube sits in. If you have an inline filter, change it.
If your engine is a chain saw/weed-eater type, you most likely have a filter in the tank. Also check the plastic tubing gas line for kinks.
Other than this, the other answerers are correct - carburetor is dirty - needs cleaning.
Good luck.

Answer 4

So how long did the engine sit with old gas in it? As others have said the carb probably needs a clean and rebuild. To prevent problems in the future either drain the tank and run the engine until all fuel is used up or add gas stabilizer before long term storage. Sta-bil and other brands of fuel stabilizer are available at most auto parts stores, Home Depot, Lowes, Walmart and hardware stores. It's cheap insurance. Much cheaper than getting your card rebuilt evry few years.

Answer 5

Modern small engines no longer have fuel/air adjustments on them. (federal mandates) If your engine must have the choke on, then it is clogged and must be dissembled, cleaned thoroughly, and reassembled. The only other options are to have a small engine shop do the cleaning, or replace the carburetor

Answer 6

first of all i could verify the air filter out. i decide to propose checking the air filter out first because of the fact fairly some the time (particularly with push/pull form backyard mowers that are low to the floor) they have an inclination to suck in grass and leaves to that end clogging the filter out. it quite is usually a solid concept to alter the filter out each year or whilst ever you modify the oil. it is likewise a solid concept to alter the spark plug each year besides. The carburetor desires a undeniable velocity of air passing by way of its narrowest section starting to be a venturi result. This venturi result creates a low stress on the jet this is contained in the midsection of the tube contained in the midst of the carburetor. The low stress creates a vacuum that "sucks" the gasoline from the bowl into the dashing air on into your combustion chamber. With that being pronounced i does not be suprised in case you have a number of of of right here: a million. undesirable gasoline. Did you empty the gasoline out in the past you saved it away? If no longer then it may ought to be drained and crammed with new. 2. Clogged carburetor jet holes. in case you have a clogged hollow (or holes) then the venturi result contained in the carburetor can't pull in sufficient gasoline for the engine to have the right mix of air to gasoline. whilst ever you hold it on choke there's a butterfly valve that closes proscribing the air pass by potential of somewhat. this supplies greater gasoline to the cylinder so it may hearth much less stressful. on your case it makes the air to gasoline ratio greater efficient (no longer suitable yet greater efficient than whilst choke is off). once you swap choke off it makes the engine run lean whick potential it has greater air. i wish this facilitates. If no longer then I i wish you discovered something considering which you by no potential be attentive to next 365 days you will possibly have another problem and the understanding you gained from examining this purely could help you out.

Answer 7

Simlpy adjust the mixture screw untill the engine runs with the choke open.

Answer 8

Bart has the correct answer. Most likely you are talking about a Briggs and they have a diaphram carburetor. It needs a rebuild kit and a good cleaning.

yes
