Question about Garden

1 Answer

I have a yerfdog with 6 hp tecumseh. It has set up for about 4yrs. I replaced carb and it fired right up but above half throttle it starts sputtering and loosing power. The carb is one of those nonadjustable ones that I do not like. Motor idles perfect. It was given to me and governor springs had been tampered with but I have corrected that. I put on jack stand and disconnected governor and ran carb by hand and it sputters above half throttle just the same. I have not been into motor yet but considering valve lash. I need some suggestions. Thanks

Carb not getting enough gas se if float is metal and adjust to let higher level in bowl

    I have already tried that and made no difference. I need a way to check rpm. Have no way of knowing if it is running to high rpm. In my opinion it still shouldn't cut out.

SOURCE: Sputters & quits at proper RPM for engaging trans or mowing deck

If the choke has an adjustment point, then adjust the choke to a good overall working powerband. If it still doesn't act correctly, look for vacuum leaks. If it is an option, you may want to install a manually operated choke lever.

It might not be disengaging the mower deck all the way off. I had this problem on an older model.

SOURCE: throttle control won't work after i cleaned the

Hi again Ed,
Starting at the carb throttle shaft, your linkage rod (with tiny spring wrapped around it) should be connected directly to the governor's arm. If there's more than one hole in the arm, connect the rod in the upper-most hole.
Now, at the base of the governor's arm is another hole (possibly on a tab jutting from the arm). The main governor spring should be hooked in this hole and then back to the sliding throttle control that moves when the lever on the dash is moved. (This one definitely has a tab and hole.)

The choke cable end hooks directly on the choke shaft and it has intuitive movement. Verify that the choke butterfly closes and opens relative to the cable control on the tractor's dash.

To insure that we only do this procedure ONCE, and we get it right the first time, let's set the internal governor to base-line at this time.

With everything bolted back up, move the throttle control lever on the tractor's dash to full throttle. Then get a 3/8 wrench and a slotted screwdriver and locate the round governor shaft coming out of the engine block. The governor arm attaches to this with a clamping-bolt. You will notice that the round shaft is slotted for a screwdriver as well.
Loosen the clamping bolt slightly with your 3/8 wrench, insert your screwdriver and rotate the round shaft clockwise until it stops. (It has VERY little travel, so turn it both ways to verify that your are at FULL clockwise position.)
Hold screwdriver there and move the governor's arm in the same (clockwise) direction until the carb's throttle is set to WIDE OPEN throttle. Still holding the screwdriver clockwise, retighten the clamping bolt with the wrench.
Next, move the throttle lever on the dash of the tractor to idle and back to full several times and observe the carb's throttle shaft, it should come down from full throttle to idle and back again freely.

Start the engine and be prepared to shut it off if it over-revs.
If it doesn't over-rev, your base-line settings are correct.

By bending the tab on the sliding throttle control (the one that has the main spring attached) you can now increase or decrease spring tension and change top speed of the engine. Do this in small increments and if you have a tachometer for single cylinder's set top speed to 3400-3600 RPM.

Sorry this is lengthy, but as mentioned above, we only want to do this once.

Hope this helps, and feel free to ask away if you need more info!

SOURCE: motor chokes and misses under moderate load and loses power

Sounds to me as tho it might need a carburetor adjustment, providing there is an adjustment screw on the carb. Sounds like the engine is running a bit lean. Did this problem occur right after the carb cleaning, or was it there in advance? Is there a fuel filter that might be clogged?

MTD snowblower with Tecumseh engine 8 hp stalls out when chock is adjusted to run position


hello ,your engine is a tecumseh HMSK90-156525D, Sounds like carb. may need adjusting. Take the heat box off to expose carb. the heat box is the metal box surrounding the caeb., there should be 2 adjustment screws- 1 on the bottom of the bowl and 1 on the side of the carb just above the edge of the bowl ( depending how the carb sets off the engine - if the carb comes straight out it will be on the side facing towards the front of the snow blower or if it goes towards the handles then standing other side of the snow blower the screw will be facing you), turn both screws in til they just bottom out the turn them out 1 1/4 turns out then start the machine. While the machine is running at low idle turn the screw on the side of the carb. in (clockwise) a little at a time listening for the engine to start to rev up and then start to rev down, bog or studder then turn back slightly to bring idle back up. Once the idle is up then the screw on the very top of the carb. turn that out to lower idle to a normal idle. Repeat those adjustments till you cant get the idle to go up anymore. Now for the screw on the bottom of the bowl- move the throttle up to max and turn the screw in till you hear it rev up higher and starts to bog or sputter then turn it back slightly to bring the high rev to a smooth rev. That should take care of it. If it does not solve it then the carb may need cleaning then the adjustments done again. If you need more help on this please feel free to ask. Sometimes you have to do process of elimination and you start with the easiest first. Also the adjustments should help with the carbon build up on the plug.692509.pdf (application/pdf Object)
i have included the manual to give you a good understanding of the carb, page 7 to 25, hope this helps,don't forget the 4 thumbs up,any comments welcome,thank you.~~

if it sat that long it could be a lot of things, I would replace the fuel filter first of all, get a can of carb cleaner and as the motor runs at mid to high rpm's spray the cleaner right in the carb barrel, if you've ben driving it with that old gas in it,, either dump it out and clean it, or add a can of gas dry , not knowing which motor you have I don't know if its a carb or fuel injected if its the latter, add some fuel injector cleaner to the gas, you may have to clean the throttle body

Hi, I have an older toro snowblower w/ tecumseh 7 hp. When idling it is fine,but with full throttle the engine seems to over rev. I've adjusted the 2 carb settings to specs and it seemed to run well, but...


The carburetor settings should be to make the engine run correctly, not meet some specification. The upper jet is for idle adjustment and the lower adjustment is for high speed running. It the lower jet is too far CW, the engine will be running lean and tend to miss. Too far CCW and the engine will run 'muddy' and tend to blow black smoke from the exhaust. Throttle speed is determined by a balancing act between two springs, the governor, and the throttle position. Generally, there are several options for spring placement--a series of holes drilled in the throttle arm and the governor arm set this balance. Have the springs been replaced? Have you tried a fresh spark plug? You may require professional assistance on the throttle adjustment. Hope this helps!

8hp Tecumseh engine how to adjust carb. when I put throttle on high it sputters drop the throttle back down its okay?


These symptoms indicate a rich mixture. Assuming the carb is the original (and therefore correct) one, and that it has an adjustable main jet, turn in the main jet adjustment screw on the bottom of the float bowl until the engine runs smooth.

If there is no adjustment on the float bowl, the carb will have to be removed and properly cleaned (ultrasonic cleaner recommended).
