824 Toro snowthrower leaking fuel!

I have an 824 Toro snowthrower. I has started leaking gas from around the idle speed screw and from where the fuel line connects to the carb there is a constant flow of fuel. Any ideas on how to stop the flow of fuel besides shutting of the fuel valve, could it be the the needle stuck in the float. If so where is it located in the bowl!!! Also whenever the engine is primed, fuel shoots out of a small hole located above the idle mixture screw!! any ideas will be greatly appreciated, snow is on it's way!!!

    So what is the easiest way to locate that line. Not to mechanically inclined.

  • bnjay Feb 19, 2009

    GReat thanks so much, very helpful, now where is the needle located in the carb. I know where the float is and I was told that it might just be the needle that is stuck open causing the gas to continually flow. or possibly a small hole in the float keeping it open because it will not float as well with gas in it!!!

  • bnjay Feb 20, 2009

    Thanks so much, found the problem, Took the float off and sure enough there was a small crack on it near the hinge. Cleaned it up/emptied the fuel out of it and put a small bead of soder on it. Works like a charm. Now I just have to readjust the carb and i am good to go. Wouldn't you know it, the snow missed us. Oh well, you give great advice.

SOURCE: Is the carb adjustment screw on bottom

Hello

>>The Following is an Instruction File I made for Correcting this Problem. Any Input is Appreciated.
>>****All the Carburetor Adjustments are the Same for Lawn Mower and Trimmers.
>>There are Several Location for the Air Mixture Screws.
>>The Idle Air Mixture Screws are Usually Located at the Top of the Carburetor Bowl and the Top of the Carburetor Body.
>>If the Main Air and Idle Air Mixture Screws are Side by Side on the Side of the Carburetor, then the Idle Air is the Nearest to the Engine.
>>The Main Jet Air Mixture Screw is Located in the Bottom of the Carburetor Bowl or Beside the Idle Air Screw on the Side of the Carburetor Body.
>>The Engine Idle Screw is Usually Easy to Identify because you can See where it Makes Contact with the Carburetor Throttle Shaft Plate Stop Ear. The H and L Air Mixture Screws Go Into the Body of the Carburetor and the Tips Cannot be Seen.
>>Some of the Older Model Carburetors have the Main Jet Mixture Screw Straight in from the Top of the Carburetor Body (this is Rare anymore).
>>If you have Cleaned the Carburetor (Disassembled and Soaked Overnight in Carburetor Cleaner (I Use Gunk). Then Blow Out the Passages with Compressed Air and Install a New Kit if Required.
>>Now Setting the Air Mixture Screws:
>>****Turn the Idle Air and Main Air Mixture Screws In Until SNUG **Do Not Jam** Then Reverse Both Screws 1 1/2 Turns.****
>>Holding the Throttle Full Open, Start the Engine.
>>Turn the Main Air Mixture Screw Clockwise Until Proper Revs are Obtained. Occasionally you May have to Turn this Counter Clockwise to Achieve the Proper Revs. Now Allow the Engine to Idle.
>>Set the Engine Idle Screw (Not Idle Air) so the Engine will Stay Running if Required.
>>Now Set the Idle Air Mixture Screw so there is No Hesitation when Throttling from Idle to Full Throttle.
>>Reset the Engine Idle if Required. If This Carburetor has a Single Air Adjustment.
>>Use the Section Above that Pertains to Full Throttle RPM Air Mixture Screw and then Adjust the Screw if Required to Eliminate Any Hesitation when Rapidly Throttling from Idle to Full Throttle.**

Please, Do Not Hesitate, If you Hit a Snag or this Does Not Correct the Problem, I am Here if You Require More Assistance.

Good Luck

SOURCE: My lawnboy 10304 runs about one minute and shuts down. Any ideas?

It sounds like it is 2 stroke.
Carefully remove the carb bowl, by undoing the brass bolt.
Examine the brass bolt for a small pin-hole in the side.
Use a piece of corn-broom NEVER anything else !!! and poke the hole(S) to make sure they are clear.
Blow out with air if available.
You can use this method to clean out all the carb orifices carefully.

Hope it helps,

Andy.

I own this same one. Mine stalls out after a few secs if I don't have the mulch plug all the way engaged. It's worth checking to make sure before messing around with bigger stuff.

Certified BLOWER EXPERT
This item is equipped with an electric starter, regardless of the age of the gas (Unless there is rust persent in the GAS tank), the unit will many times still turn over. This unit is also known to have problems with its COLD START or start for very cold temperature. This is what I did to fix my same problem. Attempt to move the unit into a warmer climate such as a garage, cover it will several blankets, (These blankets may get gas on them CAUTION), and allow the unit to warn up. When the unit is COLD, the metal inside the unit contracts and is not in the exact same condition as it was when you purchased the unit. Further, warming up the parts naturally will allow the metal to warm up and greatly increase the possibility of an electric start. Please try this option first.

I have a Toro snowthrower Model 38472. How do I drain the fuel so that I can put it away for the summer?


Joe, page 18 in your manual tells you what to . Drain the fuel from the tank and carburetor by performing the following steps: A. Loosen the fuel-tank cap. B. Unscrew, but do not remove, the small screw on the side of the carburetor fuel bowl (Figure 33) until the fuel begins to drain from the carburetor. Drain the fuel into an approved fuel container. Important: Do not remove the carburetor bowl bolt on the bottom of the carburetor. Figure 33 1. Carburetor bowl bolt-do not remove 2. Small screw on carburetor C. Wait for a few minutes until the fuel has drained, then install the fuel cap and tighten the small screw on the carburetor. Note: Use a handheld Phillips screwdriver to tighten the carburetor screw. Over tightening the screw could strip it and cause leaking. 5. Dispose of unused fuel properly. Recycle it according to local codes, or use it in your automobile. 6. Remove the spark plug. 7. Squirt 2 teaspoons of oil into the spark plug hole. 8. Install the spark plug by hand and then torque it to 27-30 N-m (20-22 ft-lb). 9. With the ignition key in the OFF position, pull the recoil starter slowly to distribute the oil on the inside of the cylinder. 10. Disconnect the ignition key from the lanyard and store the ignition key in a safe place. 11. Clean the machine. 12. Touch up chipped surfaces with paint available from an Authorized Service Dealer. Sand affected areas before painting, and use a rust preventative to prevent the metal parts from rusting. 13. Tighten any loose fasteners. Repair or replace any damaged parts. 14. Cover the machine and store it in a clean, dry place out of the reach of children. Allow the engine to cool before storing it in any enclosure. The first link is a download for your manual. Check the attached links,instruction and guides, Good luck

Toro 824 snowblower starts fine but won't keep running and new gas new plug as well cleaned the whole carb


Is there an adjustment screw on the carburetor if there is turn it out a little at a time. This sets the amount of gas going into the carb and lets it run the way it should. I hope you have one as this is the answer to many engine problems. When you say you cleaned the whole carb did you clean the fuel jet. It won't run if the jet is dirty.

How correct toro l/mower engine racing


Check the idling setting screw is not holding open the throttle butterfly common fault to fix if the engine races esp when no load is applied the idle throttlexpostion is to high thus the engine runs faster at idle turn the screw located on either the butterflyistelf so less screw threes is against the carb body this should start lowering the idle speed of the engine it should be around the 900 RPM approx for idling and top rev of 3500 at full throttle a rev counter is displaying a extra high rev count the it's the oil governed at fault or malfunctioning or sticking this will cause and engine to race badly to the point of engine destruction eventually
You may need to adjust the movement of the governing leavers etcetera best done by qualified servicing personnel a lawnmower mechanic etc

My toro weed trimmer starts good runs great for a few minutes then starts to bogg out then dies, will start back up but won't stay running.i already replaced the fuel tank, lines and filter.


Check the air filter isn't dirty.
If the machine runs ok on high speed but cuts out while idling, the idle speed may be too low. There is usually an adustment screw for increasing the speed.
If the fuel line is a flexible type which moves around inside the tank, check it is able to move freely because if you are cutting at awkward angles, the end of the line can end end up above the surface of the fuel, **** in air and airlock the line. You can eliminate this as the problem by fully filling the tank.
Check whether there is a one way check valve on the tank. This vents air into the tank as the fuel leaves for the carburettor. Sometimes particles of dirt can get stuck in this.

I have a Toro 524 with Tecumseh engine, model 38040 8 0000640. I am rebuilding the carb and would like to know what are basic settings for idle and hi/low speed screws?


The high speed mixture screw is initially set at 1 & 1/2 turns out. Then adjust it to give good acceleration and top speed, while not closing the screw more than you need to. The low speed mixture screw is set at 3/4 of a turn out. Adjust that, to give a smooth idle. The 3rd screw, the idle speed screw, is set to give a low idle speed without stalling.

Hard starting and poor running


Hi,

Try running the engine without the filter and check if the idle would smoothen, maybe a little high. If problem persist, then it would be fuel delivery problem. If the idle is constant (but high), then some sort of blockage on the air filter or a vacuum leak.


Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.
